Features

• Fourth generation FemtoClock® NG technology

• Universal Frequency Translator

• Zero ppm frequency translation

• Two outputs, individually programmable as LVPECL or LVDS

• Outputs may be individually set to use 2.5V or 3.3V output

levels

• Individually programmable output frequencies: 7.29MHz up to

1200MHz

• Two differential inputs support the following input types:

LVPECL, LVDS, LVHSTL, HCSL

• Input frequency range: 8kHz to 710MHz

• Hitless switching between inputs

• Crystal input frequency range: 16MHz to 40MHz

• Holdover support in the event both inputs fail

• One factory-set register configuration for power-up default state

• Configurations customized via One-Time Programmable ROM

• Settings may be overwritten after power-up via I2C

• I2C Serial interface for register programming

• RMS phase jitter at 156.25MHz, using a 40MHz crystal

(12kHz - 20MHz): 507fs (typical), Low Bandwidth Mode (FracN)

• Supports ITU-T G.8262 Synchronous Ethernet equipment slave

clocks (EEC option 1 and 2)
