The STV0056A from STMicroelectronics is a BICMOS integrated circuit designed for satellite sound and video processing. It handles all necessary signal processing from the tuner to the audio/video output connectors, making it versatile for various satellite systems.
Key audio features include two independent sound demodulators with PLL demodulation supporting 5-10MHz frequency synthesis. The FM demodulator bandwidth is programmable to accommodate FM deviations from ±30kHz to ±400kHz, with selectable de-emphasis options (50/75µs, J17, or none). It also supports the Wegener Panda system and includes two auxiliary audio inputs and outputs, with gain-controlled, muteable, and high-impedance audio outputs suitable for twin tuner applications.
For video processing, the STV0056A offers a 6-bit composite video gain control ranging from 0 to 12.7dB, a selectable video inverter, and two selectable video de-emphasis networks. It incorporates a 6x3 video matrix and an adjustable black level output for on-board videocrypt decoders. High-impedance mode video outputs are also available for twin tuner applications.
Miscellaneous features include 22kHz tone generation for LNB control, I2C bus control with selectable chip addresses (06HEX or 46HEX), and a low power stand-by mode. The device integrates both audio and video matrix functionalities.
