LA72714VA
Overview
For JPN TV
Multi Channel Television Sound Decoder IC
The LA72714VA is a JPN MTS (Multi Channel Television Sound) Decoder IC.
Features
* With SIF circuit, alignment-free* STEREO channel separation. * In Base Band signal input mode, separation is adjusted by input level. * Three I2C slave-addresses are prepared. * The maximum output level is as large as 4.2dBV. (Frequency = 1kHz, distortion = less than 3%, VCC = 5V, TYP) * The external clock is unnecessary. * A couple of external input terminal is prepared.
Functions
* Stereo & Bilingual demodulation. * Stereo & Bilingual detection. * JUST CLOCK OUT.

SIF INPUT
Input terminal for SIF. The input impedance is about 5k. Be care for about pattern layout of the input circuit, because of causing buzz-beat and buzz by leaking noise signal into the input terminal. (The noise signal depending on sound is particularly video signal and chroma signal and so on. VIF carrier becomes noise signal.)

I2C BUS serial interface specification
(1) Data Transfer Manual This IC adopts control method(I2C-BUS) with serial data, and controlled by two terminals which called SCL(serial clock) and SDA (serial data).At first, set up*1 the condition of starting data transfer, and after that, input 8 bit data to SDA terminal with synchronized SCL terminal clock. The order of transferring is first, MSB (the Most Scale of Bit), and save the order. The 9th bit takes ACK (Acknowledge) period, during SCL terminal takes `H', this IC pull down the SDA terminal. After transferred the necessary data, two terminals lead to set up and of *2 data transfer stop condition, thus the transfer comes to close. *1 Defined by SCL rise down SDA during `H' period. *2 Defined by SCL rise up SDA during `H' period. (2) Transfer Data Format After transfer start condition, transfers slave address (1000 000*) to SDA terminal, control data, then, stop condition (See figure 1). Slave address is made up of 7bits, 8th bit*3 shows the direction of transferring data, if it is `L' takes write mode (As this IC side, this is input operation mode), and in case of `H' reading mode (As this IC side, this is output operation mode). Data works with all of bit, transfer the stop condition before stop 8bit transfer, and to stop transfer, it will be canceled the transfer dates. *3 It is called R/W bit. Fig.1 DATA STRUCTURE "WRITE" mode
START Condition Slave Address R/WL ACK Control data ACK STOP condition
Fig.2 DATA STRUCTURE "READ" mode
START condition Slave Address R/WH ACK Internal Data * ACK STOP condition
Output data as follows ; bit8 is result of STERO DET bit7 is result of BILINGUAL DET bit6 is Initial Condition `H' bit5 to bit1 are fixed to `L' (3) Initialize
(H : STEREO) (H : BILINGUAL)
This LSI is initialized for circuit protection. Initial condition is "01h (Main-Mode) ".
