VP531E/VP551E

NTSC/PAL Digital Video Encoder

Advance Information

Supersedes DS4573 1.4 May 1997 edition

DS4573 - 2.3 October1998

The VP531/VP551 converts digital Y, Cr, Cb, data into

analog NTSC/PAL composite video and S-video signals

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 Cb, Y, Cr, Y

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

REC 656 is included in the data stream when the VP531 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.

PIN 1

GP64

Two 9 bit digital to analog converters (DACs) are used

to convert the digital luminance and chrominance data into

analog signals. An inverted composite video signal is

generated by summing the complementary current outputs

of each DAC. An internally generated reference voltage

provides the biasing for the DACs.
