The MAX4399 audio/video switch is ideal for digital set-
top box applications. The MAX4399 provides video and
audio routing from the MPEG decoder source to the TV,
VCR, and AUX SCART (peritelevision) connectors. In
addition, the TV audio channel features clickless
switching and programmable volume control from
-56dB to +6dB in 2dB steps. The device can mix an
auxiliary audio tone into the TV audio channel and can
mix the stereo audio signal into a mono audio signal.
The MAX4399 directly drives an external RF modulator
with a composite video with blanking and sound
(CVBS) signal created by an on-chip luma/chroma
(Y/C) mixer and external RLC trap filter. The MAX4399
features a fast-mode I
allowing communication at data rates up to 400kbps.
The MAX4399 operates with standard +5V and +12V
single supplies and supports slow and fast switching.
All video and audio inputs are AC-coupled. The DC
biases of all input and output signals are set to pre-
defined levels. All video outputs, including the RF mod-
ulator, drive standard 150Ω loads. Red, green, and
blue (RGB) outputs feature a programmable gain of
+6dB ±1dB. All other video outputs have a fixed +6dB
gain. The VCR and AUX audio output gains are pro-
grammable for -6dB, 0dB, and +6dB.
The MAX4399 is available in a compact 68-pin thin
QFN package and is specified for the 0°C to +70°C
commercial temperature range. The MAX4399 evalua-
tion kit is available to help speed designs.
