4fsc Clock Generator
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

Notes:
*1 Sync separation level
Measure the level where SG1 input signal and TP3 output signal synchronize when 1VP-P staircase wave
sync signal level is raised from 0V.
SG2 : 1VP-P staircase wave
1VP-P

*2 ACC input amplitude range
Defined as separate chroma signal burst signal amplitude that can be input to chroma input.
*3 APC1 frequency pull-in range
Defined as the smaller of the differences when input signal frequency is changed from high to fO and from
low to fo when TP2 output is not synchronized to SG1 input signal and when it is synchronized.
*4 VCO1 free run frequency deviation
Defined as the difference between TP2 output signal frequency and fO.
*5 The standard for the separate chroma signal is burst signal 143mVP-P.
