LC7456A
No.6733-1/6
Overview
The LC7456A receives the composite video signal from the V / C (Video Chroma) signal processor and extracts the
closed caption data. This data and a clock signal, generated by an on-chip PLL, are then sent to the decoder IC. The
LC7456A is a CMOS version of the LA7945 IC also currently in production. The differences between the LA7945 and
the LC7456A are a change from Bipolar to CMOS technology, a smaller package size (22 pins to 16 pins), and a
reduction in the external circuitry requierd.
An LC8640XX series microcontroller is needed to perform the decoding after the LC7456A has extracted the caption
data from the composite video signal.
Features
Low power consumption due to CMOS process
Accurate caption signal extraction using a built-in pead hold circuit and digital technology.
Power Requirement : 5V
