FS6131

FS6131 Programmable Line Lock Clock Generator IC 1.0 Key Features Complete programmable control via I2C™-bus Selectable CMOS or PECL compatible outputs External feedback loop capability allows genlocking Tunable VCXO loop for jitter attenuation 2.0 General Description The FS6131-01 is a monolithic CMOS clock generator/regenerator IC designed to minimize cost and component count in a variety of 2 electronic systems. Via the I 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 SCL SDA ADDR VSS XIN XOUT XTUNE VDD 1 2 3 16 15 14 CLKN CLKP VDD FBK REF VSS EXTLF LOCK/IPRG FS6131 4 5 6 7 8 13 12 11 10 9 16-pin 0.150" SOIC Figure 1: Pin Configuration ©2008 SCILLC.
