CXA1592Q/R
Encoder for CCD Color Camera
Description
The CXA1592Q/R is a bipolar IC developed as an
encoder for CCD color cameras.
Color difference and luminance signals are input
to be output as composite video and Y/C separate
signals.
The CXA1592 is a variant of the CXA1392 in
which the down/up ratio and level of shapness
signal have been changed from 1 : 3 to 1.5 : 1.5.
