* 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.

picture Y/C/J BGP output as the timing pulse.
* IIC BUS compatible; two bus lines (SCL, SDA) allow various adjust-
ments 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 50/60Hz vertical frequency (forced control
possible).
