4fsc Clock Generator MM1093
4fsc Clock Generator
Monolithic IC 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
