CXA7002R I2C Bus Compatible Audio Video (AV) Switch & Electronic Volume Control Description The Sony CXA7002R is an Audio/Video switch designed primarily for application in Digital Set Top Boxes. It provides video and audio routing from the digital encoder source to the TV and VCR scart (peri-television) connectors. In addition, the TV audio output has a programmable volume control. The chip is programmed by means of an I2C interface and can www.DataSheeotp4Ue.rcaotme from a single or dual power supply.
