FemtoClock

Crystal-to-LVDS

Clock Generator

ENERAL

ESCRIPTION

The 844021-01 is an Ethernet Clock Generator. The 844021-01

uses an 18pF parallel resonant crystal over the range of 24.5MHz

– 34MHz. For Ethernet applications, a 25MHz crystal is used. The

844021-01 has excellent <1ps phase jitter performance, over the

1.875MHz – 20MHz integration range. The 844021-01 is packaged

in a small 8-pin TSSOP, making it ideal for use in systems with

limited board space.
