MAX4399 19-2925 Rev 1 7/06 Audio/Video Switch for Three SCART Connectors General Description Features The MAX4399 audio/video switch is ideal for digital set- Low -86dB Video Signal-to-Noise Ratio top box applications. The MAX4399 provides video and 150 Driver on All Video Outputs, Including the audio routing from the MPEG decoder source to the TV, RF Modulator VCR, and AUX SCART (peritelevision) connectors. In addition, the TV audio channel features clickless Full CVBS Loop-Through on AUX SCART switching and programmable volume control from Programmable Audio Gain Control of -56dB to -56dB to +6dB in 2dB steps. The device can mix an auxiliary audio tone into the TV audio channel and can +6dB (TV Audio Outputs) mix the stereo audio signal into a mono audio signal. Clickless Audio Switching (TV Audio Outputs) The MAX4399 directly drives an external RF modulator Programmable Clamp or Bias on Red/Chroma with a composite video with blanking and sound (CVBS) signal created by an on-chip luma/chroma Video Inputs (Y/C) mixer and external RLC trap filter. The MAX4399 Programmable Video Gain of +6dB, 1dB on RGB 2 features a fast-mode I C-compatible 2-wire interface Outputs allowing communication at data rates up to 400kbps. The MAX4399 operates with standard +5V and +12V +5V and +12V Standard Supply Voltages single supplies and supports slow and fast switching. 27MHz -3dB Large-Signal Bandwidth on All Video All video and audio inputs are AC-coupled.
