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)
