Description

The MAX4397 dual SCART switch matrix routes audio and video signals between an MPEG encoder and two external SCART connectors under I²C control, and meets the requirements of EN50049-1, IEC 933-1, Canal+, and BSkyB standards. The video and audio channels feature input source selection multiplexers, input buffers, and output buffers for routing all inputs to selected outputs. The MAX4397D audio encoder input is differential DC-coupled, while the MAX4397S audio encoder input is single-ended AC-coupled. Except for the MAX4397D's audio encoder input, all other inputs and outputs are AC-coupled with internal DC-biasing set to predefined levels. The MAX4397 provides programmable gain control from +5dB to +7dB in 1dB steps for Red, Green, and Blue component video signals. All other video outputs have a fixed +6dB gain. Additional features include an internal Luma and Chroma (Y/C) mixer that generates a Composite video signal (CVBS) to supply an RF modulator output, and internal video reconstruction lowpass filters with passband ripple between -1dB and +1dB from 100kHz to 5.5MHz. The MAX4397 TV audio channel features clickless switching and programmable volume control from -56dB to +6dB in 2dB steps. The VCR audio output also has programmable gain for -6dB, 0dB, or +6dB. The device also generates monaural audio from left and right stereo inputs. All audio drivers deliver a 3.0VRMS minimum output. The MAX4397 operates with standard 5V and 12V power supplies and supports slow-switching and fast-switching signals. The I²C interface programs the gain and volume control, and selects the input source for routing. The MAX4397 is available in a compact 48-pin thin QFN package and is specified over the 0°C to +70°C commercial temperature range.
