Audio/Video Switch For Dual SCART Connectors
General DescriptionThe MAX4397 dual SCART switch matrix routes audio
and video signals between an MPEG encoder and two
external SCART connectors under I2C* control, and
meets the requirements of EN50049-1, IEC 933-1,
Canal+, and BskyB standards.
The video and audio channels feature input source
selection multiplexers, input buffers, and output buffers
for routing all inputs to selected outputs. The MAX4397D
audio encoder input is differential DC-coupled, while the
MAX4397S audio encoder input is single-ended AC-
coupled. Except for the MAX4397D’s audio encoder
input, all other inputs and outputs are AC-coupled with
internal DC-biasing set to predefined levels.
The MAX4397 provides programmable gain control from
+5dB to +7dB in 1dB steps for Red, Green, and Blue
component video signals. All other video outputs have a
fixed +6dB gain. Additional features include an internal
Luma and Chroma (Y/C) mixer that generates a
Composite video signal (CVBS) to supply an RF
modulator output, and internal video reconstruction low-
pass filters with a cutoff frequency of 6MHz. The
MAX4397 TV audio channel features clickless switching
and programmable volume control from -56dB to +6dB in
2dB steps. The VCR audio output also has programmable
gain for -6dB, 0dB, or +6dB. The device also generates
monaural audio from left and right stereo inputs. All audio
drivers deliver a 3.0VRMSminimum output.
The MAX4397 operates with standard 5V and 12V
power supplies and supports slow-switching and fast-
switching signals. The I2C interface programs the
gain and volume control, and selects the input source
for routing.
The MAX4397 is available in a compact 48-pin thin
QFN package and is specified over the 0°C to +70°C
commercial temperature range.
