CXA
1145P/M
RGB Encoder
Description Packa e Outline Unit: mm
The
CXA 1145P/M encoder converts
an
ana-
log.RGB signal
to
a composite video signal.
CXA 1145P 24
pin
DIP
With its built-in circuit various pulses required
for
an
encoder, composite video outputs
are
ob-
tained just by inputting the composite sync and
analog
RGB
signal.
