FS7140 fiche technique
FS7140, FS7145
Programmable Phase-
Locked Loop Clock
Generator
Description
The FS7140 or FS7145 is a monolithic CMOS clock generator/
regenerator IC designed to minimize cost and component count in a
variety of electronic systems. Via the I2Cbus interface, the
FS7140/45 can be adapted to many clock generation requirements.
The length of the reference and feedback dividers, their fine
granularity and the flexibility of the post divider make the FS7140/45
the most flexible standalone PLL clock generator available.
