Video Signal Driver for DVD Players MM1623
Video Signal Driver for DVD Players
Monolithic IC MM1623www.DataSheet4U.com
October 8, 2001
Outline
This IC is a 6-ch video driver IC developed for DVD players and recorders. It includes a switching function for
an LPF, whith attenuates the DAC noise element, to support both progressive and interlace signals. The driver
comprises a 2-channel 6dB amp with 75Ω driver.
In additon, external ESD protection diodes can be reduced by a DC superposition function (S1, S2 pins), and
enhancement of the ESD protection elements for the output pins.
Features
1. Enables to driver a 2-channel 6dB amp with 75Ω driver
2. S/N=83dB typ.
3. Includes a 6dB amp
4. Includes a switching function for an LPF to support progressive and interlace signals
5. Includes a high-performance 4th-order LPF.
6. 6.75MHz/100kHz max. ±1.0dB 27MHz/100kHz typ. -40dB
7. ±15KV ESD for aerial discharge
8. Includes a DC superposition function in S1 and S2 pins
9. The component circuity can support RGB sgnals with the control pin.
