The VP5311C/VP5511C 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 VP5311C/

VP5511C 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.

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.
