CXA2025AS
E96413-ST
Y/C/RGB/Sync/Deflection for Color TV
Description
The CXA2025AS 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
Features
• I2C 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
