GENERAL DESCRIPTION

FEATURES

The ICS84327 is a Crystal-to-3.3V LVPECL • 6 LVPECLoutputs

,&6

Clock Synthesizer/Fanout Buffer designed for

• Crystal oscillator interface

• Output frequency range: 77.76MHz to 625MHz

HiPerClockS™

SONET, 10 Gigabit Fibre Channel and 10 Giga-

bit Ethernet applications and is a member of the

HiperClockS family of High Performance Clock

• Crystal input frequency: 19.44MHz, 25MHz or 25.5MHz

Solutions from ICS. The output frequency can be set using

the frequency select pins and a 19.44MHz crystal for SONET

frequencies, or a 25MHz crystal for 10 Gigabit Ethernet fre-

quencies, or a 25.5MHz crystal for a 10 Gigabit Fibre Chan-

nel. The low phase noise characteristics of the ICS84327 make

it an ideal clock for these demanding applications.

• RMS phase jitter at 155.52MHz, using a 19.44MHz crystal

(12KHz to 20MHz): 3.4ps (typical)

Phase noise:
