Ordering Information
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.
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, allowing support for the European SCART con-
nector.
The DACs can drive doubly-terminated (37.5) lines, and
run at a 2x oversampling rate to simplify the analog output
filter requirements.
