ADVANCE INFORMATION

VDP 313xY

Micronas

Video Processor Family

1. Introduction

The VDP 313xY is a video IC family of high-quality sin-

gle-chip video processors. Modular design and a sub-

micron technology allow the economic integration of

features in all classes of TV sets. The VDP 313xY fam-

ily is based on the VDP 31xxB including YCRCB inputs

for DVD component signals.

The main features of the VDP 3130Y are

1.1. Features

Video Decoding and Processing

– four CVBS, one S-VHS input,

one YCRCB component input

– integrated high-quality A/D converters and associ-

ated clamp and AGC circuits

– adaptive 2H comb filter Y/C separator

– multistandard color decoder PAL/NTSC/SECAM

including all substandards

– multistandard sync decoder

– automatic standard recognition

– black-line detector

– linear horizontal scaling (0.25...4), as well as nonlin-

ear horizontal scaling “Panoramavision”

– black-level expander

– dynamic peaking

– soft limiter (gamma correction)

– color transient improvement

RGB Processing and Deflection

– programmable RGB matrix

– two analog RGB / Fastblank inputs

– half-contrast switch

– picture frame generator

– scan velocity modulation output

– high-performance H/V deflection

– separate ADC for tube measurements

– EHT compensation

– angle and bow correction

– one 20.25 MHz crystal, few external components

–I2C-Bus Interface

– 64-pin PSDIP package
