Video Signal Driver for DVD Player
Monolithic IC MM1623XFBE
Outline
This 6ch video driver IC was developed for use in DVD players/recorders. The LPF that attenuates the DAC noise element has a built-in switching function to handle both progressive and interlace signals. In addition, the driver structure is 6db, 75 x 2 lines. Also, the number of external ESD protection diodes has been reduced thanks to the S1/S2 DC superimpose function and reinforced output pin ESD protection element.
Features
1. 75W driver can drive 2 lines. 2. S/N=83dB typ. 3. Built-in 6dB amp. 4. Built-in filter switching function for progressive/interlace signal 5. Built-in high performance 4th LPF. 6. 6.75MHz/100kHz max. 1.0dB 27MHz/100kHz typ. -40dB 7. +/- 15KV ESD for aerial discharge. 8. S1/S2 Built-in DC superimpose function. 9. Control pin allows component circuit to handle RGB signals.
