FEMTOCLOCKS™ CRYSTAL-TO-3.3V LVPECL FREQUENCY

SYNTHESIZER W/INTEGRATED FANOUT BUFFER

ICS843246I

GENERAL DESCRIPTION

FEATURES

The ICS843246I is a Crystal-to-3.3V LVPECL Clock

• Six LVPECL outputs

ICS

HiPerClockS™

Synthesizer/Fanout Buffer designed for Fibre

Channel and Gigabit Ethernet applications and is

a member of the HiperClockS™ family of High

Performance Clock Solutions from IDT. The output

• Crystal oscillator interface

• VCO range: 490MHz to 680MHz

• Crystal input frequency range: 25MHz to 33.333MHz

frequency can be set using the frequency select pins and a

25MHz crystal for Ethernet frequencies, or a 26.5625MHz

crystal for a Fibre Channel.The low phase noise characteristics

of the ICS843246I make it an ideal clock for these demanding

applications.

• RMS phase jitter at 125MHz, using a 25MHz crystal

(1.875MHz to 20MHz): 0.41ps (typical)

• Full 3.3V or 3.3V core, 2.5V output supply mode

Core/Output

3.3V/3.3V

3.3V/2.5V

• -40°C to 85°C ambient operating temperature
