General Description
The STV2310 is a high-quality video front-end circuit for processing all analog standards into a
digitalized 4:2:2 YCrCb video format. It processes NTSC/PAL/SECAM CVBS signals, as well as
conventional analog RGB or YCrCb signals.
This circuit outputs demodulated chrominance, in-phased luminance and sliced Vertical Blanking
Interval (VBI) data for the most common services such as Teletext, Closed Caption, WSS, VPS,
Gemstar.
The STV2310 does not need an external synchronization system. It extracts all necessary
synchronization signals from CVBS or Y signals, and delivers the horizontal, vertical and frame
signals either on dedicated pins or embedded into the digital bit stream.
It features automatic standard recognition and automatic selection of the optimal Y/C separation
algorithm according to the standard and has extensive output scaling capabilities. The STV2310
chip includes an analog RGB capture feature and programmable automatic mixing with the main
picture digital output.
8-bit ITU-R BT.601/656 and Square Pixel output standards are supported.
The STV2310 provides a cost-effective solution for digitized TV, LCD TV/monitors, digital TV, STB,
video surveillance/security, video conferencing, video capturing devices and PC video card.
It can be used as a stand-alone chip working with third-party products, as a companion chip to the
TV processor STV3500, STV3600 for digitized 100-Hz/ProScan CRT TVs, or as a companion chip
to the TV processor STV3550 for LCD-TVs.
All sub-level blocks operate at the frequency used as a sampling frequency (f
