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 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 operati...
