Introduction

The MAX4399 audio/video switch is ideal for digital settop box applications. The MAX4399 provides video and audio routing from the MPEG decoder source to the TV, VCR, and AUX SCART (peritelevision) connectors. In addition, the TV audio channel features clickless switching and programmable volume control from -56dB to +6dB in 2dB steps. The device can mix an auxiliary audio tone into the TV audio channel and can mix the stereo audio signal into a mono audio signal. The MAX4399 directly drives an external RF modulator with a composite video with blanking and sound (CVBS) signal created by an on-chip luma/chroma (Y/C) mixer and external RLC trap filter. The MAX4399 features a fast-mode I2C-compatible 2-wire interface allowing communication at data rates up to 400kbps. The MAX4399 operates with standard +5V and +12V single supplies and supports slow and fast switching.
