Overview

HMP8190, HMP8191 Data Sheet May 1999 File Number 4499.
1 NTSC/PAL Video Encoder The HMP8190 and HMP8191 are NTSC and PAL encoders designed for use in systems requiring the generation of highquality NTSC and PAL video.
YCbCr digital video data drive the P0-P15 inputs.
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 added together.
The result drives the C analog output.
The digital Y and C data are also added together and drive the composite analog output.
The DACs can drive doubly-terminated (37.
5Ω) lines, and run at a 2x oversampling rate to simplify the analog output ﬁlter requirements.
