Description

The HMP8156 NTSC and PAL encoder is designed for use in systems requiring the generation of high-quality NTSC and PAL video from digital image data.

About the HMP8156, 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 5MHz 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 HMP8156, allowing support for the European SCART connector.

The DACs of the HMP8156 can drive doubly-terminated (37.5W) lines, and run at a 2x oversampling rate to simplify the analog output filter requirements.
