Description

The HMP8170, HMP8171, HMP8172, and HMP8173 NTSC and PAL encoders are designed for use in systems requiring the generation of high-quality NTSC and PAL video.

About The HMP8170, HMP8171, HMP8172, and HMP8173, 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 two composite analog outputs.

The DACs of the HMP8170, HMP8171, HMP8172, and HMP8173 can drive doubly-terminated (37.5W) lines, and run at a 2x oversampling rate to simplify the analog output filter requirements.
