Description

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.

About the HMP8156A, 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 with the HMP8156A, allowing support for analog component RGB and the European SCART connector.

The DACs can drive doubly-terminated (37.5W) lines, and run at a 2x oversampling rate to simplify the analog output filter requirements. Any unused DACs of HMP8156A may be powered down to reduce power consumption.
