Stratum 3 and GR-253, ITU-T G.813, and G.781
SETS
• Supports ITU-T G.823, G.824 and G.8261 for 2048
kbit/s and 1544 kbit/s interfaces
• Programmable synthesizers generate any clock-
rate from 1 Hz to 750 MHz
• Two precision synthesizers generate clocks with
jitter below 0.8 ps RMS for 10 G PHYs
• Programmable digital PLL synchronize to any clock
rate from 1 Hz to 750 MHz
• Flexible two-stage architecture translates between
arbitrary data rates, line coding rates and FEC
rates
• Digital PLL filter jitter from 0.1 mHz, 1 mHz,
10 mHz, 0.1 Hz, 1.7 Hz, 3.6 Hz, 7 Hz, 14 Hz,
28 Hz, 56 Hz, 112 Hz, 224 Hz, 448 Hz or 896 Hz
• Automatic hitless reference switching and digital
holdover on reference fail
• Four reference inputs configurable as single
ended or differential
• Eight LVPECL outputs and four LVCMOS outputs
• Operates from a single crystal resonator or clock
oscillator
