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
