Very low jitter <1ps

Miniature 6 pad package, RoHS Compliant

DESCRIPTION

OUTLINE & DIMENSIONS

GP series VCXOs use fundamental mode (inverted mesa) crystal to

achieve wide frequency deviation with stable and clean signals. No

multiplier, overtone crystal or phase lock loop technique is used. As a

result Jitter is as low as for instance 1ps for the 155.520 MHz for

SONET/SDH application. Additionally, the inherent advantages of

differential PECL ECL signal transmission provide improved noise

immunity making the system less susceptible to ground noise.
