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
