Overview
The LC7455A/M extracts the closed caption signal
superimposed on a video signal during the vertical return
period and, under the control of a clock signal provided by
the decoder IC, transfers that signal to the IC (usually a
microcontroller) that decodes the closed caption data. The
LC7455A/M supports four operating modes. Modes 1 and
2 can be used for XDS. In these modes, the LC7455A/M,
in combination with the decoder IC (microcontroller),
extracts the caption signal superimposed on field 2 and
uses it for NTSC VCR functions such as the automatic
time and date setting function. In modes 3 and 4, the
LC7455A/M, in combination with the decoder IC
(microcontroller), extracts the caption signal
superimposed on fields 1 and 2 and uses it for NTSC TV
applications (mode 3) or PAL TV applications (mode 4).
Functions
Low power dissipation achieved by fabrication in a
CMOS process.
Stable caption signal extraction achieved by a built-in
peak hold circuit and the use of digital technology.
Operating supply voltage: 5 V ±10%
