Description

M66239FP is high speed synchronizing clock generator with frequency synthesizer which is fabricated by high

performance silicon gate CMOS process technology.

It is able to output clock in sync with external trigger. And it features excellent synchronizing precision (sync accuracy:

jitter) over a wide range frequency band.

Also, it has frequency synthesizer function which is able to modulate input frequency by resister setting before normal

operation. Frequency modulation resolution is high accuracy 0.01%.

And in order to process the Y/M/C/K printing signal processing by 1 chip, M66239FP integrate fore synchronizing

clock generator macro with frequency synthesizer function.

Also, this part can use various applications as frequency synthesizer LSI.
