CXA2095S
Y/C/RGB/Sync/Deflection for Color TV
Description
The CXA2095S is a bipolar IC which integrates
the luminance signal processing, chroma signal
processing, RGB signal processing, and sync and
deflection signal processing functions for NTSC
system color TVs onto a single chip.
The following functions have been added to the
same function IC, CXA2025S.
1) Vertical sync pull-in speed switching function
2) YUV SW Y signal switching function
3) fsc output pin
Features
•
I
2
C bus compatible
•
Sync signal processing uses a countdown system
with non-adjusting H/V oscillator frequencies
•
Built-in deflection compensation circuit capable of
supporting various wide modes
•
Non-adjusting Y/C block filter
•
Built-in AKB
•
Video signal I/Os: Y/C separation input, Y/color
difference input, analog RGB input and RGB
output
•
YUV SW Y signal switching function allows picture
quality adjustment for the Y signal in the same
manner as for the normal Y signal even when
Y/color difference input is selected
Applications
Color TVs (4:3, 16:9)
