FS6131-01/FS6131-01g Programmable Line Lock Clock Generator IC
Data Sheet
1.0 Features
• Complete programmable control via I
2
C™-bus
• Selectable CMOS or PECL compatible outputs
• External feedback loop capability allows genlocking
• Tunable VCXO loop for jitter attenuation
2.0 Description
The FS6131-01 is a monolithic CMOS clock generator/regenerator IC designed to minimize cost and component count in a variety of electronic
systems. Via the I
2
C-bus interface, the FS6131-01 can be adapted to many clock generation requirements.
The ability to tune the on-board voltage-controlled crystal oscillator (VCXO), the length of the reference and feed-back dividers, their granularity,
and the flexibility of the post divider make the FS6131-01 the most flexible stand-alone phase-locked loop (PLL) clock generator available.
3.0 Applications
• Frequency synthesis
• Line-locked and genlock applications
• Clock multiplication
• Telecom jitter attenuation
