Description

The CXA2000Q is a bipolar IC which integrates the

luminance

signal

processing,

chroma

signal

processing, RGB signal processing, and sync and

deflection signal processing functions for NTSC/PAL

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

• 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
