HMP8154, HMP8156A Data Sheet October 1998 File Number 4343.3 NTSC/PAL Encoders The HMP8154 and HMP8156A NTSC and PAL encoders are designed for use in systems requiring the generation of high-quality NTSC and PAL video from digital image data. YCbCr or RGB digital video data drive the P0-P23 inputs. Overlay inputs are processed and the data is 2x upsampled. The Y data is optionally lowpass filtered to 6MHz and drives the Y analog output. Cb and Cr are each lowpass filtered to 1.3MHz, quadrature modulated, and summed. The result drives the C analog output. The digital Y and C data are also added together and drive the two composite analog outputs. The YCbCr data may also be converted to RGB data to drive the DACs, allowing support for analog component RGB and the European SCART connector.
