The MAX4079 filters and buffers video (NTSC/PAL/DVB) and stereo audio signals from the MPEG decoder of a cable/satellite receiver, VCR/DVD player, or a TV to an external load. The MAX4079 has luma-chroma (Y-C) and composite (CVBS) video inputs with one Y-C and two CVBS outputs. All video inputs are AC-coupled with internal DC biasing on the chroma input and active clamps for the luma and composite. The MAX4079 video reconstruction filters have a 6MHz cutoff frequency and 50dB attenuation at 27MHz. The filters are matched with flat group delay for standard-definition video. The video gain is fixed at +6dB to drive a 75Ω back-terminated load (150O) to unity gain. The video outputs can be either DC- or AC-coupled and are powered by a single +5V supply. The MAX4079 audio amplifiers have differential inputs for optimum performance, but can be used with single-ended sources with external biasing. The audio channels have a fixed gain of +6dB and deliver 2.6VRMS output with a differential input of ±1.85V. The audio amplifiers operate from a +9V to +12V single supply and feature an internal bias generator. An on-chip mixer also provides a mono output, with +3dB gain, derived from the left and right audio channels. The MAX4079 is available in 24-pin TSSOP package, and is fully specified over the 0°C to +70°C commercial temperature range. The MAX4079 Evaluation Kit is available to help speed designs.
