Video Signal Driver for DVD Player
Monolithic IC MM1568
Outline
This IC is a video signal driver that supports 6-ch progressive, and was developed for use in DVD players.
It contains a low pass filter that attenuates the noise element during DA conversion, and a 6dB amp and
75
X3-line driver (component circuit is 2-line).
It also has a SAG correction pin for reducing output coupling capacitance, and reinforced output pin ESD
protection element allows reduction of external ESD protection diodes.
Features
(1)Has SAG correction pin.
(2)3-line drive possible with 75
driver.
(3)Built-in fourth low pass filter.
Frequency response: 6.75MHz ±1dB / 27MHz 27dB min.
13.5MHz ±1dB / 54MHz 24dB min.
(4)Built-in 6dB amp.
(5)Built-in power save function.
(6)S/N=80dB typ.(Y/C mix:74dB typ.)
(7)For aerial discharge, ±15kV ESD protection withstand pressure (IEC standard)
(8)Component circuit control pin allows support for RGB signals.
Package
SSOP-34A
Applications
(1)DVD players that support progressive video
(2)Digital STB
(3)Other digital video equipment
