VP5313/VP5513
NTSC/PAL Digital Video Encoder

The VP5313/VP5513 converts digital Y Cr Cb data into analog PAL or NTSC composite video, and also provides
33 23
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
34
22
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
order to make the most efficient use of the 9 bit dynamic range. The device accepts data inputs complying with CCIR
