1 Video Signal Driver for DVD Players MM/MM Video Signal Driver for DVD Players Monolithic IC MM/MM October, 00 Outline This IC is a -ch video driver IC developed for DVD players and recorders. It includes a switching function for an, whith attenuates the DAC noise element, to support both progressive and interlace signals. The driver comprises a -channel db amp with Ω driver. In additon, external ESD protection diodes can be reduced by a DC superposition function (S, S pins), and enhancement of the ESD protection elements for the output pins. Features. Enables to driver a -channel db amp with Ω driver. S/N=dB typ.. Includes a db amp. Includes a switching function for an to support progressive and interlace signals. Includes a high-performance th-order...mhz/0khz max. ±.0dB 7MHz/0kHz typ. -0dB 7. ±KV ESD for aerial discharge. Includes a DC superposition function in S and S pins. The component circuity can support RGB sgnals with the control pin. Package SOP-B Pin Assignment SOP-B (TOP VIEW) CIN CrOUT MUTE 7 CVBSIN CbOUT YC MIX.
