GENERAL DESCRIPTION

FEATURES

The ICS84325 is a Crystal-to-3.3V LVPECL

• 6 differential 3.3V LVPECL outputs

• Crystal oscillator interface

ICS

Frequency Synthesizer with Fanout Buffer and a

HiPerClockS™

member of the HiPerClockS™ family of High

Performance Clock Solutions from ICS. The

output frequency can be programmed using

• Output frequency range: 106.25MHz to 250MHz

• Crystal input frequency: 25MHz and 25.5MHz

• Output skew: 60ps (maximum)

frequency select pins. The low phase noise characteristics

of the ICS84325 make it an ideal clock source for Fibre

Channel 1, Fibre Channel 2, Infiniband and Gigabit

Ethernet applications.

• RMS phase jitter at 212.5MHz, using a 25.5MHz crystal

(637KHz to 10MHz): 2.76ps

• Phase noise: Typical at 212.5MHz
