S-terminal Compatible Video I/O
CXA1812Q
Description
The CXA1812Q is an IC developed for processing
video I/O signals in VCRs. This IC has a built-in
video output circuit designed especially for use with
viewfinders (VF), making this IC optimal for use in
camcorders. In addition, both the video input
system and the viewfinder video output system
provide title insertion functions, making it possible to
insert characters and graphics into video signals.
Features
• Built-in video output circuit for use with viewfinders
(title insertion function (white or black character),
compatible with SY/C and composite video output)
• Built-in C system EE/PB switch
EE : Electric-Electric monitor mode
• Title insertion function (white or black character)
• C MUTE function for playback in PAL mode
(Outputs C signal used for generating the
composite video signal)
• Built-in switch for switching between the two input
systems, Y and C
• Built-in 75 Ω driver for the two input systems, Y
and C
(with power saving function)
