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
