Application
The Connor-Winfield SCG2000 Series
provides high precision phase lock loop
frequency translation for the
telecommunication applications.
SCG2000 Series is well suited for use in
line cards, service termination cards and
similar functions to provide reliable
reference, phase locked, synchronization
and low phase gain for TDM, PDH, SONET
and SDH network equipment. The
SCG2000 Series provides a jitter filtered,
wander following output signal
synchronized to a superior Stratum or peer
input reference signal.
Features
• 3.3V High
Precision PLL
• Tri-State Capability
• Active Alarms
• Guaranteed Free
Run ±20ppm
• 1 Sec. Acquisition
