VP5313/VP5513

NTSC/PAL Digital Video Encoder

Supersedes DS4509 1.9 September 1997 edition

DS4509 - 2.2 October 1998

The VP5313/VP5513 converts digital Y Cr Cb data into

analog PAL or NTSC composite video, and also provides

simultaneous RGB outputs. These additional converters can

optionally provide separate luma and chroma outputs plus a

further composite video channel. All outputs are capable of

driving doubly terminated 75Ω loads with standard video

levels.

All D/A converters are to 9 bit accuracy, and are provided with

27MHz oversampled data. The latter simplifies the

requirement for external analog anti-aliasing filters, and

reduces the sinx/x distortion inherent in D/A converters.

Separate digital scaling is applied to the chroma data path in

ordertomakethemostefficientuseofthe9bitdynamicrange.

The device accepts data inputs complying with CCIR

recommendation 656. In this format 4:2:2 video is multiplexed

onto an 8 bit bus using a 27MHz clock. Active video markers

are embedded into the data stream and extracted by the

VP5313/VP5513. Optionally the user can supply separate

horizontal and vertical syncs, and colour can be genlocked to

an external subcarrier if necessary.

In an alternative operating mode the VP5313/VP5513 can

be configured as the source of sync for the rest of the system.

In this master mode the horizontal and vertical sync pins

become outputs, and any control codes in the CCIR656 bit

stream are ignored.

The VP5313/VP5513 supports the insertion of teletext

data through a serial interface. An internal filter shapes the

data edges.
