Description

The device is composed of phase-lock loop with integrated VCXO for use in clock recovery, data retiming, frequency translation and clock smoothing applications in telecom and datacom systems.

Features

? PLL with quartz stabilized VCXO

? Crystal output jitter less than 20ps

? Dual redundant reference input clocks with loss of signal detection

? Manual or automatic switch over between reference input clocks

? VCXO provides smooth output transition during switch over of input clocks

? Lock detection

? Selectable metal mask options for phase detectors, op. Amps, and charge pump

? Loss of signals alarm

? Return to nominal clock upon LOS

? Input data rates from 8 kb/s to 40 Mb/s

? Tri-state output

? User defined PLL loop response

? NRZ data compatible

? +3.3 and +5.0V supply voltage

Applications

? Frequency translation

? Clock Smoothing, Clock Switching
