Overview

Description

The 813321-04 is a two stage device – a VCXO followed by a FemtoClock® PLL. The FemtoClock PLL can multiply the crystal frequency of the VCXO up to a range of 122MHz to 160MHz, with a random rms phase jitter of less than 1ps (1.875MHz – 20MHz). This phase jitter performance meets the requirements of 1Gb/10Gb Ethernet, 1Gb, 2Gb, 4Gb and 10Gb Fibre Channel, and SONET up to OC48.
