MM1568

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 allows reduction of external ESD protection diodes. Features (1)Has SAG correction pin. (2)3-line drive possible with 75Ω 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.
