CXA2019AQ Overview
The CXA2019AQ is a bipolar IC which integrates the luminance signal processing, chroma signal processing, and sync signal processing functions for NTSC/PAL system color TVs onto a single chip.
CXA2019AQ Key Features
- Sub picture bright and white balance can be adjusted by using the main picture Y/C/J BGP output as the timing pulse
- I2C BUS patible; two bus lines (SCL, SDA) allow various adjustments and user controls
- Countdown system eliminates need for H and V oscillator frequency adjustment
- Non-adjusting Y system filters (chroma trap, delay line)
- Automatic identification of color system (forced control possible)
- Automatic identification of 50/60Hz vertical frequency (forced control possible)
- Built-in delay line aperture correction
- Built-in dynamic picture (black expansion) function
- bination with a non-adjusting SECAM chroma decoder allows configuration of multiple systems
