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

Applications
1. TV
2. VCR
