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 75 loads with standard video levels. All D/A converters are to 9 bit accuracy, and are provided with 2 7 M H z 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 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.
