PCD3311C; PCD3312C
* DTMF, modem and musical tone generation * Stabilized output voltage level * Low output distortion with on-chip filtering conforming to CEPT recommendations * Latched inputs for data bus applications * I2C-bus compatible * Selection of parallel or serial (I2C-bus) data input (PCD3311C). 2 GENERAL DESCRIPTION
used, and a separate microcontroller is required to control the devices. Both the devices can interface to I2C-bus compatible microcontrollers for serial input. The PCD3311C can also interface directly to all standard microcontrollers, accepting a binary coded parallel input. With their on-chip voltage reference the PCD3311C and PCD3312C provide constant output amplitudes which are independent of the operating supply voltage and ambient temperature. An on-chip filtering system assures a very low total harmonic distortion in accordance with CEPT recommendations. In addition to the standard DTMF frequencies the devices can also provide: * Twelve standard frequencies used in simplex modem applications for data rates from 300 to 1200 bits per second * Two octaves of musical scales in steps of semitones.
The PCD3311C and PCD3312C are single-chip silicon gate CMOS integrated circuits. They are intended principally for use in telephone sets to provide the dual-tone multi-frequency (DTMF) combinations required for tone dialling systems. The various audio output frequencies are generated from an on-chip 3.58 MHz quartz crystal-controlled oscillator. A separate crystal is

PCD3311C; PCD3312C
Data inputs (PCD3311C)
The Input Control Logic decodes the input data to determine whether DTMF, modem or musical tones are selected; and which particular tone or combination of tones is required. A code representing the required tones is sent to the Divider Selection ROM which selects the correct division ratio in both of the Frequency Dividers (or in one divider, if only a single tone is required). The Oscillator circuit provides a square wave of frequency 3.58 MHz. Each Frequency Divider divides the frequency of the Oscillator to give a serial digital square wave with a frequency simply related to that of the required tone. The output from each Frequency Divider goes to a DAC, which is also fed by a clock derived from the oscillator. Using these two signals, the DAC produces an approximate sine wave of the required frequency, with an amplitude derived from the Voltage Reference. The output from the DAC goes to an Adder where, for DTMF, it is combined with the output from the other DAC. The output from the Adder goes through two stages of Low Pass Filters to give a smoothed tone (single or dual), and finally to the TONE output. 7.2 Clock/oscillator connection
Inputs D0, D1, D2, D3, D4 and D5 are used in the parallel data input mode of the PCD3311C. Inputs D0 and D1 are also used in serial input mode when they act as the SCL and SDA inputs respectively. Inputs D0 and D1 have no internal pull-down or pull-up resistors and must not be left open in any application. Inputs D2, D3, D4 and D5 have internal pull-down. D4 and D5 are used to select between DTMF dual, DTMF single, modem and musical tones (see Table 1). D0, D1, D2 and D3 select the tone combination or single tone within the selected application. They also, in combination with D4, select the standby mode. See Tables 2, 3, 4 and 5. PCD 3312C has no parallel data pins as data input is via the I2C-bus. Table 1 D5 Use of D5 and D4 to select application D4 APPLICATION
LOW LOW DTMF single tones; musical tones; standby LOW HIGH DTMF dual tones (all 16 combinations) HIGH LOW modem tones HIGH HIGH musical tones 7.5 Strobe input (PCD3311C )
The timebase for the PCD3311C and PCD3312C is a crystal-controlled oscillator, requiring a 3.58 MHz quartz crystal to be connected between OSCI and OSCO. Alternatively, the OSCI input can be driven from an external clock of 3.58 MHz. 7.3 Mode selection (PCD3311C)
The STROBE input (with internal pull-down) allows the loading of parallel data into D0 to D5 when MODE is HIGH. The data inputs must be stable preceding the positive-going edge of the strobe pulse (active HIGH). Input data are loaded at the negative-going edge of the strobe pulse and then the corresponding tone (or standby mode) is provided at the TONE output. The output remains unchanged until the negative-going edge of the next STROBE pulse (for new data) is received. Figure 5 is an example of the timing relationship between STROBE and the data inputs. When MODE is LOW, data is received serially via the I2C-bus.
The MODE input selects the data input mode for the PCD3311C. When MODE is connected to VDD (HIGH), data can be received in the parallel mode. When connected to VSS (LOW) or left open, data can be received via the serial I2C-bus. PCD 3312C has no MODE input as data input is via the I2C-bus only.

I2C-bus clock and data inputs
7.8
I2C-bus data configuration (see Fig.6)
SCL and SDA are the serial clock and serial data inputs according to the I2C-bus specification, see Chapter 8. SCL and SDA must be pulled up externally to VDD. For the PCD3311C, SCL and SDA are combined with parallel inputs D0 and D1 respectively - D0/SCL and D1/SDA operate serially only when MODE is LOW. 7.7 Address input
The PCD3311C and PCD3312C are always slave receivers in the I2C-bus configuration. The R/W bit in is thus always LOW, indicating that the master (microcontroller) is writing. The slave address in the serial mode consists of 7 bits: 6 bits internally fixed, 1 externally set via A0. in the serial mode, the same input data codes are used as in the parallel mode. See Tables 2, 3, 4 and 5. 7.9 Tone output
Address input A0 defines the least significant bit of the I2C-bus address of the device (see Fig.6). The first 6 bits of the address are fixed internally. By tying the A0 of each device to VDD (HIGH) and VSS (LOW) respectively, two different PCD3311C or PCD3312C devices can be individually addressed on the bus. Whether one or two devices are used, A0 must be connected to VDD or VSS.
The single and dual tones provided at the TONE output are first filtered by an on-chip switched-capacitor filter, followed by an active RC low-pass filter. The filtered tones fulfil the CEPT recommendations for total harmonic distortion of DTMF tones. An on-chip reference voltage provides output tone levels independent of the supply voltage. Tables 3, 4 and 5 give the frequency deviation of the output tones with respect to the standard DTMF, modem and music frequencies.

Power-on reset
In order to avoid an undefined state when the power is switched ON, the devices have an internal reset circuit which sets the standby mode (oscillator OFF). 7.11 TABLES OF INPUT AND OUTPUT

8 I2C-BUS INTERFACE
PCD3311C; PCD3312C
The I2C-bus is for two-way communication between different ICs or modules. It uses only two lines, a serial data line (SDA) and a serial clock line (SCL), both of which are bi-directional. Both lines must be connected to a positive supply via a pull-up resistor when connected to the output stages of a device. Data transfer may be initiated only when the bus is not busy. 8.1 Bit transfer (see Fig.7)
One data bit is transferred during each clock pulse. The data on the SDA line must remain stable during the HIGH period of the clock pulse as changes in the data line at this time will be interpreted as control signals.
SDA
SCL data line stable; data valid change of data allowed

8.2
Start and stop conditions (see Fig.8)
Both data and clock lines remain HIGH when the bus is not busy. A HIGH-to-LOW transition of the data line, while the clock is HIGH is defined as the start condition (S). A LOW-to-HIGH transition of the data line while the clock is HIGH is defined as the stop condition (P).

Acknowledge
The number of data bytes transferred between the start and stop conditions from transmitter to receiver is not limited. Each byte of eight bits is followed by one acknowledge bit. The acknowledge bit is a HIGH level put on the bus by the transmitter whereas the master generates an extra acknowledge after the reception of each byte. Also a master must generate an acknowledge after reception of each byte that has been clocked out of the slave transmitter. The device that acknowledges has to pull down the SDA line during the acknowledge-related clock pulse. Set-up and hold times must be taken into account to ensure that the SDA line is stable LOW during the whole HIGH period of the acknowledge-related clock pulse. A master receiver must signal an end of data to the transmitter by not generating an acknowledge on the last byte that has been clocked out of the slave. In this event the transmitter must leave the data line HIGH to enable the master to generate the stop condition.

8.5 Timing specifications
PCD3311C; PCD3312C
The PCD3311C and PCD3312C accept data input from a microcontroller and are `slave receivers' when operating via the I2C-bus. They support the `standard' and `low-speed' modes of the I2C-bus, but not the `fast' mode detailed in "The I2C-bus and how to use it" document order no. 9398 393 40011. The timing requirements for the devices are described in Sections 8.5.1 and 8.5.2. 8.5.1 STANDARD MODE
Masters generate a bus clock with a maximum frequency of 100 kHz. Detailed timing is shown in Fig.11, where the two signal levels are LOW = VIL and HIGH = VIH, see Chapter 11. Figure 12 shows a complete data transfer in standard mode. The time symbols are explained in Table 6.

14 SOLDERING 14.1 Introduction
PCD3311C; PCD3312C
There is no soldering method that is ideal for all IC packages. Wave soldering is often preferred when through-hole and surface mounted components are mixed on one printed-circuit board. However, wave soldering is not always suitable for surface mounted ICs, or for printed-circuits with high population densities. In these situations reflow soldering is often used. This text gives a very brief insight to a complex technology. A more in-depth account of soldering ICs can be found in our "IC Package Databook" (order code 9398 652 90011). 14.2 14.2.1 DIP SOLDERING BY DIPPING OR BY WAVE
Several techniques exist for reflowing; for example, thermal conduction by heated belt. Dwell times vary between 50 and 300 seconds depending on heating method. Typical reflow temperatures range from 215 to 250 C. Preheating is necessary to dry the paste and evaporate the binding agent. Preheating duration: 45 minutes at 45 C. 14.3.2 WAVE SOLDERING
Wave soldering techniques can be used for all SO packages if the following conditions are observed: * A double-wave (a turbulent wave with high upward pressure followed by a smooth laminar wave) soldering technique should be used. * The longitudinal axis of the package footprint must be parallel to the solder flow. * The package footprint must incorporate solder thieves at the downstream end. During placement and before soldering, the package must be fixed with a droplet of adhesive. The adhesive can be applied by screen printing, pin transfer or syringe dispensing. The package can be soldered after the adhesive is cured. Maximum permissible solder temperature is 260 C, and maximum duration of package immersion in solder is 10 seconds, if cooled to less than 150 C within 6 seconds. Typical dwell time is 4 seconds at 250 C. A mildly-activated flux will eliminate the need for removal of corrosive residues in most applications. 14.3.3 REPAIRING SOLDERED JOINTS
The maximum permissible temperature of the solder is 260 C; solder at this temperature must not be in contact with the joint for more than 5 seconds. The total contact time of successive solder waves must not exceed 5 seconds. The device may be mounted up to the seating plane, but the temperature of the plastic body must not exceed the specified maximum storage temperature (Tstg max). If the printed-circuit board has been pre-heated, forced cooling may be necessary immediately after soldering to keep the temperature within the permissible limit. 14.2.2 REPAIRING SOLDERED JOINTS
Apply a low voltage soldering iron (less than 24 V) to the lead(s) of the package, below the seating plane or not more than 2 mm above it. If the temperature of the soldering iron bit is less than 300 C it may remain in contact for up to 10 seconds. If the bit temperature is between 300 and 400 C, contact may be up to 5 seconds. 14.3 14.3.1 SO REFLOW SOLDERING
Reflow soldering techniques are suitable for all SO packages. Reflow soldering requires solder paste (a suspension of fine solder particles, flux and binding agent) to be applied to the printed-circuit board by screen printing, stencilling or pressure-syringe dispensing before package placement.
Fix the component by first soldering two diagonallyopposite end leads. Use only a low voltage soldering iron (less than 24 V) applied to the flat part of the lead. Contact time must be limited to 10 seconds at up to 300 C. When using a dedicated tool, all other leads can be soldered in one operation within 2 to 5 seconds between 270 and 320 C.
