Synchronous Clock Generators
The SCG2000 and SSCG2500 offer significant improvements in performance, especially in applications where network line cards using these SCGs are cascaded together in series. Enhanced performance includes lower phase gain for lower percent overshoot and greater bandwidth.
Additional benefits include smoother switching into Free Run mode, closer tracking of signal "wander," better isolation inputs and outputs, and better temperature transient performance.
Features of the new SCG2000 and SCG2500 include phase locked output frequency control, intrinsically low jitter crystal oscillator, one or two selectable references @ 8 kHz, tri-stateable oscillator and alarm outputs, fast .35 second acquisition time, 3.3 V power supply, surface mount, DIL package, low voltage CMOS and TTL compatible outputs and a frequency range of 1.544-125 MHz.
