CXA2025AS Overview
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.
CXA2025AS Key Features
- I2C bus patible
- Sync signal processing uses a countdown system with non-adjusting H/V oscillator frequencies
- Built-in deflection pensation 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 norm
