Features & Benefits

Supports the requirements of Telcordia GR-253 and GR-1244 for Stratum 3, 4E, 4 and SMC clocks, and the requirements of ITU-T G.781 SETS, G.813 SEC, G.823, G.824, and G.825 clocks
Internal APLL provides standard output clock frequencies up to 622.08 MHz with jitter < 3 ps RMS suitable for GR-253-CORE OC-12 and G.813 STM-16 interfaces
Programmable output synthesizers generate clock frequencies from any multiple of 8 kHz up to 77.76 MHz in addition to 2 kHz
Provides 8 reference inputs which support clock frequencies with any multiples of 8 kHz up to 77.76 MHz in addition to 2 kHz
Supports master/slave configuration for AdvancedTCATM
Configurable input to output delay and output to output phase alignment
Optional external feedback path provides dynamic input to output delay compensation
