Features

 Generates any frequency from 2 kHz

to 945 MHz and select frequencies to

1.4 GHz from an input frequency of

2 kHz to 710 MHz

 Ultra-low jitter clock outputs with jitter

generation as low as 300 fs rms

(12 kHz–20 MHz)

 Integrated loop filter with selectable

loop bandwidth (4 Hz to 525 Hz)

 Meets OC-192 GR-253-CORE jitter

specifications

 Four clock inputs with manual or

automatically controlled hitless

switching and phase build-out

 Supports holdover and freerun

modes of operation

 SONET frame sync switching and

regeneration

 Five clock outputs with selectable

signal format (LVPECL, LVDS, CML,

CMOS)
