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

• 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

Applications

Color TVs (4:3, 16:9)
