Part Details:

19-0645; Rev 1; 5/07 EVALUATION KIT AVAILABLE Audio/Video Switch for Dual SCART Connectors MAX4397DA/SA General Description Features The MAX4397DA/SA dual SCART switch matrices route Video Outputs Drive 2VP-P into 150 audio and video signals between an MPEG encoderand two external SCART connectors under I2C control, Audio Outputs Drive 3VRMS into 10k and meets the requirements of EN50049-1, IEC 933-1, Clickless, Popless Audio Gain Control Canal+, and BSkyB standards. and Switching The video and audio channels feature input source selec- AC-Coupled Video Inputs with Internal Clamp tion multiplexers, input buffers, and output buffers for rout-ing all inputs to selected outputs. The MAX4397DA audio and Bias encoder input is differential DC-coupled, while the DC-Coupled Video Outputs MAX4397SA audio encoder input is single-ended AC-cou- pled. Except for the MAX4397DA s audio encoder input, Composite Video Signal Created Internally from all other inputs and outputs are AC-coupled with internal Y/C Inputs DC-biasing set to predefined levels. Internal Video Reconstruction Filters Provide The MAX4397DA/SA provide programmable gain control -40dB at 27MHz from +5dB to +7dB in 1dB steps for Red, Green, and Differential (MAX4397DA) or Single-Ended Blue component video signals. All other video outputshave a fixed +6dB gain. Additional features include an (MAX4397SA) Audio Encoder Input internal Luma and Chroma (Y/C) mixer that generates a Red/Chroma Switch for Bidirectional I/O Composite video signal (CVBS) to supply an RF modulator output and internal video reconstruction low- I2C-Programmable RGB Gain from +5dB to +7dB pass filters with passband ripple between -1dB and I2C-Programmable Audio Gain Control from +6dB +1dB from 100kHz to 5.5MHz. The MAX4397DA/SA TV to -56dB audio channel feature clickless switching and program-mable volume control from -56dB to +6dB in 2dB steps. Meets EN50049-1, IEC 933-1, Canal+, and BSkyB The VCR audio output also has programmable gain for Requirements -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. Ordering Information The MAX4397DA/SA operate with standard 5V and 12Vpower supplies and support slow-switching and fast- TEMP PKG switching signals. The I2C interface programs the gain PART PIN-PACKAGE
