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 mo
