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
