DDP1010

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
