General Description
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 75
Ω back-terminated load (150Ω) 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 chan-
nels 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.
