Audio/Video Switch for Dual SCART Connectors
______________________________________________________________________________________

The slow-switching feature allows for bidirectional, tri-
level, slow-switching input and output signals at pin
VCR_SS and TV_SS, respectively. The slow-switching
signals from the VCR set the aspect ratio or video source
of the TV screen. See the
Slow Switching
section.
Fast switching consists of two inputs from the encoder
and VCR, and one output to the TV to insert an on-
screen display (OSD). Fast switching is used to route
video signals from the VCR or from the encoder to the
TV. In addition, the fast-switching output can be config-
ured to a high or low voltage. Fast switching is con-
trolled through the I
2
C interface.
The digital block contains the 2-wire interface circuitry,
control, and status registers. The MAX4397 can be
configured through an I
2
C-compatible interface.
DEV_ADDR sets the I
2
C-compatible address.
SCART Video Switching
The MAX4397 switches video signals between an MPEG
decoder, TV SCART, and VCR SCART. The video switch
includes reconstruction filters, multiplexed video ampli-
fiers, and a Y-C mixer driver for an RF modulator. See
Figure 1 for the functional diagram of the video section.
While the SCART connector supports RGB, S-video, and
Composite video formats, RGB, and S-video typically
share a bidirectional set of SCART connector pins.
