Monolithic IC MM1093

4fsc Clock Generator MM1093

Outline

This IC generates a clock used for driving the CCD that configures a comb filter for Y/C separation, or for

sampling A/D and D/A converters that configure a digital comb filter.

It has a built-in subcarrier oscillator (3.58MHz or 4.43MHz) synchronized to the input chroma signal, and a

clock oscillator that is 4 times the latter. MM1093ND and NF are available for NTSC format, and MM1093PD

and PF for PAL format.

Features

1. Built-in fsc synchronized to input chroma signal and 4fsc oscillators

2. Reduced number of external parts due to 1 pin VCXO

3. +5V single power supply

Package

SOP-16A (MM1093NF, MM1093PF)

DIP-16B (MM1093ND, MM1093PD)

Applications

1. TV

2. VCR
