Jitter Attenuators

Valpey Fisher Jitter Attenuators offer a completely integrated clock/PLL timing solution for synchronization, clock and data recovery, and jitter attenuation in SONET/SDH/ATM network elements. Various models are available in LVPECL, SINE, or CMOS with multiple selectable inputs and up to four outputs up to 1.0GHz. Jitter measured over the OC-48 bandwidth (RMS 12KHz to 20MHz) is less than 0.2ps. Valpey Fisher Jitter Attenuators exceed the requirements for Telcordia GR-1244-CORE, GR-253-CORE, ITU-T G.813, and G.8261.
