Description
The CXA2050S is a bipolar IC which integrates the
luminance
signal
processing,
processing, RGB signal processing, and sync and
deflection signal processing functions for PAL/NTSC
system color TVs onto a single chip. This IC includes
deflection processing functions for wide-screen TVs,
and is also equipped with a SECAM decoder
interface, making it possible to construct a TV
system that supports multiple color systems.

C bus compatible
Compatible with both PAL and NTSC systems
(also compatible with SECAM if a SECAM decoder is connected)
Built-in deflection compensation circuit capable of supporting various wide modes
Countdown system eliminates need for H and V oscillator frequency adjustment
Automatic identification of 50/60Hz vertical frequency (forced control possible)
Non-interlace display support (even/odd selectable)
Automatic identification of PAL, NTSC, and SECAM color systems (forced control possible)
Automatic identification of 4.43MHz/3.58MHz crystal (forced control possible)
Non-adjusting Y/C block filter
One CV input, one set of Y/C inputs, two sets of analog RGB inputs (one set of which can serve as both
analog and digital inputs)
Built-in AKB circuit
Support for forcing YS1 off
