MITSUMI Video Signal Driver for DVD Player MM1568 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 75ΩX3-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
