5002C
Dual SCART A/V Switch

FUNCTIONAL DESCRIPTION
The 5002C is an audio/video switching device. The
device integrates both audio and video drivers so
that it can directly drive the SCART interface. The
use of a -5 volt supply eliminates the need for AC
coupling capacitors on the audio outputs and the
SCART audio inputs. All programmable functions of
the device are controlled through a standard I
2
C
serial interface and a set of internal registers.
The device will interface to an external video
encoder that provides six video outputs. In addition,
the 5002C includes two programmable digital
outputs and provides inputs for the TV SCART
audio/video.
SCART VIDEO SWITCHING
The device is designed to accept video signals from
an
auxiliary
SCART
connector, and an external video encoder/DAC
device. The devices include a set of analog
multiplexers that receive video signals from these
sources and allow routing of the signals to the
various video outputs. The video output drivers have
a nominal gain of 2.0 V/V to allow for a series
resistance of 62 ohms prior to the 75 ohm
termination. A block diagram of the video switching
function is provided in Figure 1. Details of the
register settings are provided in the section titled
“Serial Port Register Tables”.
