The AN5829S is a multiplex sound demodulation IC dedicated to the U.S. television and incorporates a bidirectional I2C interface (adjustment, mode SW), an AGC circuit and external stereo input switches (2 systems).
* Stereo demodulation, SAP demodulation, dbx noise reduction, AGC, external stereo input SW and I2C bus interface are integrated in a single chip * Bi-directional I2C bus makes it possible to monitor MPX input level, separation adjustment (3 places), mode changeover and receiving status. * Eliminated external parts (multi-sound block: 21 pieces 14 pieces * Lower power dissipation (VCC = 5 V, ITOT = 18 mA)

s Usage Notes
ICs for TV
1. AGC set-up method By turning on AGC, the AGC performs 0 dB at a small signal input, Boost at a medium signal and gain reduction at a big signal. It can also control the I/O characteristics of AGC by I2C as shown below: AGC characteristics

Input level (rms)
2. Guarantee of I2C operating temperature I2C bus control operation at an operating ambient temperature is theoretially guranteed based on IC design by means of the inspection using about 50% faster clock speed at the normal temperature (Ta = 25C). Namely it is a theoretical value based on IC design, therefore it is not guranteed at the shipping inspection because the inspection under a high and low temperature is not conducted. 3. Electrostatic breakdown Pay attention to the following levels: Pin 6: 200 pF, 130 V Pin 10: 200 pF, 150 V Pin 22: 200 pF, 190 V

Transmission message As transfer messages, SCL and SDA are transfered synchronouslly and serially. SCL is a constant clock frequency and SDA is address data for controlling a receiving side and is sent in parallel by synchronizing with SCL. Data are in principle sent by 8-bit 3-octet (byte) and there exists an acknowledge bit per octet. The frame structure is mentioned below: 1) Start condition When SDA becomes from high to low at SCL = high, the receiver gets ready to receive. 2) Stop condition When SDA becomes from low to high at SCL = high, the receiver stops receiving. 3) Slave address Specified for each device. If any addresses of other devices are sent, receiving will be stopped. 4) Sub-address Specified for each function. 5) Data Data for controlling 6) Acknowledge bit This is the bit that informs the master of data reception every octet. The master sends the high signal and the receiver sends back the low signal as shown with the dotted line in the above figure, thus the master acknowledges reception on the receiver side. If the low signal is not sent back, the reception will be stopped. Except for the start and stop conditions, SDA does not change at SCL = high.
