Description
The CXA2050S is a bipolar IC which integrates the luminance signal processing, chroma signal 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.

Features
• I2C 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

Applications
Color TVs (4:3, 16:9)
