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)
