SAA5261; SAA5262; SAA5263
SAA5262 and SAA5263 * Automatic Channel Installation (ACI) * Enhanced SAFARI interface providing additional commands. SAA5263 * Electronic Programme Guide (EPG) feature. GENERAL DESCRIPTION The SAA526xPS ICs are single-chip 10-page 625-line World System Teletext (WST) decoders with a high level command interface, SAFARI compatible. It has been designed so that the overall system cost is kept to a minimum. This has been achieved through the capability of the device to be driven from a single +5 V power supply, low cost 12 MHz crystal oscillator and the high level command interface, which offers the benefit of low software overhead in the TV microcontroller. The SAA526xPS offers automatic detection of Fastext or TOP transmissions. The device also incorporates a facility to detect the pages in the transmission, which allows only transmitted pages to be selected by page-up and page-down. SAA5262 and SAA5263 provide Automatic Channel Installation (ACI) information. SAA5263 provides access to Electronic Programme Guide (EPG) information.

HIGH LEVEL COMMAND INTERFACE
SAA5261; SAA5262; SAA5263
The I2C-bus interface is used to pass control commands and data between the SAA526xPS and the television microcontroller. The interface uses high level commands, which are backward compatible with the SAFARI interface. The formats for the I2C-bus transmission are as follows: Table 1 START User command I2C-bus ADDRESS System command I2C-bus ADDRESS System read I2C-bus ADDRESS I2C-bus address PIN 16 = LOW ADDRESS 01 01 100 Table 5 Control commands DATA BYTE - - - - - - - - - - - - - - - - - - COMMAND DESCRIPTION picture TV status time program 0 program 1 program 2 program 3 program 4 program 5 program 6 program 7 program 8 program 9 program 10 program 11 program 12 program 13 program 14 8 COMMAND BYTE (HEX) 1F 20 21 22 23 24 25 26 27 28 29 2B 2C 2D 2F 30 31 32 DATA BYTE - - - - - - - - - - - - - - - - - - COMMAND DESCRIPTION program 15 red green yellow subtitle text status hold reveal cancel index list toggle reveal toggle store previous subcode digit 1 digit 2 digit 3 DESCRIPTION read = 1; write = 0 ADDRESS 0110 000 PIN 16 = HIGH DESCRIPTION read = 1; write = 0 READ ACK DATA NACK STOP WRITE ACK COMMAND ACK PARAMETER ACK STOP WRITE ACK COMMAND ACK STOP

CLOCK GENERATOR
SAA5261; SAA5262; SAA5263
The oscillator circuit is a single-stage inverting amplifier in a Pierce oscillator configuration. The circuitry between pins XTALI and XTALO is basically an inverter biased to the transfer point. A crystal must be used as the feedback element to complete the oscillator circuitry. It is operated in parallel resonance. XTALI is the high gain amplifier input and XTALO is the output. To drive the device externally XTALI is driven from an external source and XTALO is left open-circuit.

EMC GUIDELINES Optimization of circuit return paths and minimisation of common mode noise will be assisted by using a double-sided PCB with a low inductance ground plane. On a single-sided PCB a local ground plane under the whole IC should be present, as shown in Fig.16. This should be connected by the widest possible connection back to the PCB ground connection and bulk electrolytic decoupling capacitor. It should preferably not connect to other grounds on the way and no wire links should be present in this connection. The use of wire links increases ground bounce by introducing inductance into the ground. The supply pins can be decoupled at the pin to the ground plane under the IC. This is easily accomplished using surface mount capacitors, which are more effective than leaded components at high frequency. Using a device socket will unfortunately add to the area and inductance of the external bypass loop.
SAA5261; SAA5262; SAA5263
A ferrite bead or inductor with resistive characteristics at high frequency may be utilized in the supply line close to the decoupling capacitor to provide a high impedance. To prevent pollution by conduction onto signal lines (which may then radiate) signals connected to the +5 V supply via a pull up resistor should not be connected to the IC side of the ferrite component. OSCGND should be connected only to the crystal load capacitors and not the local or circuit ground. Keep physical connection distances to associated active devices short. Route output traces with close proximity mutually coupled ground return paths.

SOLDERING Introduction 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 "Data Handbook IC26; Integrated Circuit Packages" (order code 9398 652 90011). Soldering by dipping or by wave The maximum permissible temperature of the solder is 260 C; solder at this temperature must not be in contact DEFINITIONS Data sheet status Objective specification Preliminary specification Product specification Limiting values
SAA5261; SAA5262; SAA5263
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. 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.
This data sheet contains target or goal specifications for product development. This data sheet contains preliminary data; supplementary data may be published later. This data sheet contains final product specifications.
Limiting values given are in accordance with the Absolute Maximum Rating System (IEC 134). Stress above one or more of the limiting values may cause permanent damage to the device. These are stress ratings only and operation of the device at these or at any other conditions above those given in the Characteristics sections of the specification is not implied. Exposure to limiting values for extended periods may affect device reliability. Application information Where application information is given, it is advisory and does not form part of the specification. LIFE SUPPORT APPLICATIONS These products are not designed for use in life support appliances, devices, or systems where malfunction of these products can reasonably be expected to result in personal injury. Philips customers using or selling these products for use in such applications do so at their own risk and agree to fully indemnify Philips for any damages resulting from such improper use or sale. PURCHASE OF PHILIPS I2C COMPONENTS
Purchase of Philips I2C components conveys a license under the Philips' I2C patent to use the components in the I2C system provided the system conforms to the I2C specification defined by Philips. This specification can be ordered using the code 9398 393 40011.
