Bi-CMOS IC
LV1110NM
Digital Surround Processor IC
Overview
The LV1110NM is a digital surround processor IC developed for miniature stereo components and radiocassette combinations. The major features built into this Bi-CMOS single-chip solution are function switching, recording volume control, surround processing, karaoke processing, 3-band graphic equalizer, and master volume control.
Features
* The built-in delay functions include input and output filters, analog-to-digital and digital-to-analog converters, delay lines with built-in memory, and delay reverberation. Other functions available are fixed matrix (L+R and L-R) and front mixing (choice of level or phase). These functions may be freely combined to easily produce a variety of surround modes and thus simulate a wide range of acoustic environments. * The built-in karaoke functions include a vocal canceler, microphone echo, key control I/O, and other support for audio multiplexing software.
* Front addition (+3 dB, -3 dB, -5 dB, mute) * I/O filters in delay block (choice of 2-, 5-, and 28-kHz low pass filters or through operation) * Reverberation functions (with built-in volume control) * Built-in SRAM (8 kilobytes) * Variable delay (choice of 15, 20, 25, 30, 40, 50, 100, and 120 ms) * Built-in VDD * I/O through or mute * Three-band graphic equalizer (boost or cut with three steps each) * Master volume control from 0 to -79 dB in 1-dB steps * QIP-64E package with 0.8-mm pin pitch

Notes on control data
* * * * *
The device latches the individual data bits of the command at the rising edge of the clock signal. One frame consists of 16 bits (A to D13). The device latches the data for the command at the rising edge of the enable signal. Maintain the clock and enable signals at High level when not controlling the LV1110NM. Maintain the enable signal at High level for at least 10 s between commands.
min. 10 s
Important note on mode control and using system muting * When the power is first applied, allow the IC sufficient time to initialize (approximately 2 seconds) and then send it commands to turn system muting off and then on. * When changing the delay, always turn system muting on and then off--that is, send the new data with the command to turn system muting on and again with the command to turn it back off. Both operations enhance reliability by forcing the device to initialize its memory. Data timing Timing Characteristic

LV1110NM Control Commands A = L, B1 = L, B2 = L * D1, D2, and D3: Function input switching. In CD and MD modes an output buffer is used, but the 6-dB amplifier output is used for tape, tuner, and EXT modes. The input impedance is 50 k. * D4, D5, and D6: Matrix mode switching and total through switching. The signal selected by the matrix is mixed to the left and right channels according to D10 and used to form the surround signal according to the D11 and D12 delay signal selection bits. In total through mode, the left and right signals are directly output with the matrix and graphic equalizer blocks bypassed to provide a high signal-to-noise ratio output. * D7: Audio rejection on/off. When this bit is set to 1, L+R mode must be selected with D4, D5, and D6. * D8: Microphone mixing on/off. * D9: Key control interface on/off. The signal (BGM) set up by the matrix block is output from pin 6 and the signal processed by key control is mixed into the left and right channels by inputting it to pin 7. * D10: Left and right channel bypass/matrix switching. When matrix is selected, monaural and karaoke multi-sound software L/R only modes can be set up. * D11: Surround signal I/O (input: pin 32, output: pin 33) on/off. * D12 and D13: Delay line signal input switching. When SW = B, the signal processed by key control can be input to the delay line. A = L, B1 = H, B2 = L * D1 and D2: Delay line output filter switching: A 5-kHz or higher low-pass filter cutoff frequency is recommended for delay times of 15 to 50 ms, and a 2-kHz low-pass filter for 100 and 120 ms delay times. * D3, D4, and D5: Reverb volume switching. Since oscillation may occur at the 0 dB setting, always use a setting of -1 dB or lower. * D6, D7, and D8: Delay time setting. * D9: System muting on/off. Always use the system muting function (D9) when changing the delay time. Turning the muting function on and the off again initializes memory and prevents incorrect operation. * D10: Left and right channel output (pins 20 and 21) muting on/off. * D11: Front mix right channel phase switching. Selects whether the delayed signal is added into the right channel in phase or out of phase relative to the left channel. * D12 and D13: Front mix level switching. A = L, B1 = L, B2 = H * D1, D2, and D3: Graphic equalizer bass boost/cut level setting. * D4, D5, and D6: Graphic equalizer mid boost/cut level setting. * D7, D8, and D9: Graphic equalizer treble boost/cut level setting. * D10 and D11: Port output high/low level settings. When set to high, the corresponding port pin is pulled up to VDD through a 51-k resistor, and when set to low, the pin is pulled down with an npn transistor (about 1 k). A = L, B1 = H, B2 = H, D1 = L * D2, D3, D4, D5, D6, D7, and D8: Left channel master volume setting. * D9, D10, and D11: Record volume setting. A = L, B1 = H, B2 = H, D1 = H * D2, D3, D4, D5, D6, D7, and D8: Right channel master volume setting. * D9: Record output signal switching. Selects function output or mixer output. * D10 and D11: Record output on/off (muting). D10 controls the pin 2 and pin 52 outputs and D11 controls the pin 3 and 53 outputs.

LV1110NM Graphic equalizer level attenuation technique
Pins 8 and 9
* Since the graphic equalizer provides a maximum boost of 10 dB, the head room is insufficient when this boost is used. Therefore, the signal level must be attenuated in the graphic equalizer block. One technique for providing this attenuation is to connect resistors in series with the external capacitors connected at pins 8 and 9 in the DC cut circuit. The formula below can be used to determine the amount of attenuation due to the value of the resistor. Attenuation: VG = 20 x log (1 - R/10 K + R) dB Example: If R = 10 k, the attenuation will be -6 dB. Pin Functions
