Introduction

The DDP 3310B is a single-chip digital Display and Deflection Processor designed for high-quality backend applications in 100/120-Hz TV sets with 4:3- or 16:9 picture tubes. The IC can be combined with members of the DIGIT 3000 IC family (VPC 32xx, TPU 3040), or it can be used with third-party products. The IC contains the entire digital video component and deflection processing and all analog interface components.

Main Features

Video processing

– linear horizontal scaling (0.25 … 4)

– non-linear horizontal scaling “panoramavision”

– dynamic peaking

– soft limiter (gamma correction)

– color transient improvement

– programmable RGB matrix

– picture frame generator

– two analog RGB/Fast-Blank inputs

Deflection processing

– scan velocity modulation output

– high-performance H/V deflection

– EHT compensation for vertical / East/West

– soft start/stop of H-Drive

– vertical angle and bow

– differential vertical output

– vertical zoom via deflection

– horizontal and vertical protection circuit

– adjustable horizontal frequency for VGA/SVGA display

Miscellaneous

– selectable 4:1:1/4:2:2 YC rCb input

– selectable 27/32-MHz line-locked clock input

– crystal oscillator for horizontal protection

– automatic picture tube adjustment (cutoff, whitedrive)

– single 5-V power supply

– hardware for simple 50/60-Hz to 100/120-Hz conversion (display frequency doubling)

– two I2C-controlled PWM outputs

– beam current limiter
