Video Signal Driver for DVD Player
Monolithic IC MM1540
Outline
This IC is a video signal driver IC for DVD players.
It outputs the composite signal, S signal and component signal required for DVD player video signals.
This IC has built-in low pass filter, clamp (ON/OFF), amp, 75W driver and Y/C-MIX circuits. + power supply or
power supply voltages can be selected, so the number of external parts can be greatly reduced.
Features
1. + power supply or power supply voltage can be selected.
+ power supply: small input coupling capacitance
power supply: I/O coupling capacitor not required
2. 2-line drive possible for 75
driver (with mute function).
3. Fourth order low pass filter built-in
frequency response: 6.75MHz 1dB/27MHz - 27dB max.
4. Select between two amp gains: 6dB and 9dB. (A: 6dB, B: 9dB)
5. Clamp ON/OFF
6. Power save function provided.
Package
SOP-28B
Applications
1. DVD player
2. Digital set-top box
3. Other digital video equipment
