MAX4399
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 a d d i t i o n , the TV audio channel features clickless s w i t c h i n g 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 w i t h a composite video with blanking and sound ( C V B S ) signal created by an on-chip luma/chroma (Y/C) mixer and external RLC trap filter. The MAX4399 features a fast-mode I2CTM-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. All video and audio inputs are AC-coupled. The DC biases of all input and output signals are set to predefined levels. All video outputs, including the RF modulator, drive standard 150 loads. Red, green, and blue (RGB) outputs feature a programmable gain of +6dB ±1dB. All other video outputs have a fixed +6dB gain. The VCR and AUX audio output gains are programmable for -6dB, 0dB, and +6dB. The MAX4399 is available in a compact 68-pin thin QFN package and is specified for the 0°C to +70°C commercial temperature range. The MAX4399 evaluation kit is available to help speed designs.

Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
