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.
