VP5311B/VP5511B

NTSC/PAL Digital Video Encoder

Advance Information

Supersedes DS4575 1.5 May 1997 version

DS4575 - 2.2 October 1998

The VP5311/VP5511 converts digital Y, Cr, Cb, data

intoanalogNTSC/PALcompositevideoandS-videosignals.

The outputs are capable of driving doubly terminated 75

ohm loads with standard video levels.

The device accepts data inputs complying with CCIR

Recommendation 601 and 656. The data is time multiplexed

on an 8 bit bus at 27MHz and is formatted as Y, Cr, Y, Cb

(i.e. 4:2:2). The video blanking and sync information from

REC 656 is included in the data stream when the VP5311/

VP5511 is working in slave mode.

The output pixel rate is 27MHz and the input pixel rate

is half this frequency, i.e. 13.5MHz.

All necessary synchronisation signals are generated

internally when the device is operating in master mode. In

slave mode the device will lock to the TRS codes or the HS

and VS inputs.

PIN 64

The rise and fall times of sync, burst envelope and

video blanking are internally controlled to be within

composite video specifications.

Three digital to analog converters (DACs) are used to

convert the digital luminance, chrominance and composite

data into true analog signals. An internally generated

reference voltage provides the biasing for the DACs.
