ADVANCE INFORMATION
VDP 313xY
Video Processor Family
1. Introduction
– black-level expander
– dynamic peaking
– soft limiter (gamma correction)
– color transient improvement
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.
RGB Processing and Deflection
– programmable RGB matrix
– two analog RGB / Fastblank inputs
– half-contrast switch
The main features of the VDP 3130Y are
– picture frame generator
1.1. Features
– scan velocity modulation output
– high-performance H/V deflection
– separate ADC for tube measurements
– EHT compensation
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
– angle and bow correction
– one 20.25 MHz crystal, few external components
– I2C-Bus Interface
– adaptive 2H comb filter Y/C separator
– multistandard color decoder PAL/NTSC/SECAM
including all substandards
– 64-pin PSDIP package
– multistandard sync decoder
– automatic standard recognition
– black-line detector
