FEMTO

CLOCKS™ CRYSTAL- -

LVCMOS/LVTTL F^REQUENCY

SYNTHESIZER

GENERAL DESCRIPTION

FEATURES

The ICS840014I is a 4 output LVCMOS/LVTTL • Four LVCMOS/LVTTL outputs, 15Ω typical output impedance

ICS

Synthesizer optimized to generate Fibre Channel

• Selectable crystal oscillator interface

HiPerClockS™

reference clock frequencies and is a member of

or LVCMOS single-ended input

the HiPerClocks^TMfamily of high performance

• Output frequency: 106.25MHz or 53.125MHz

clock solutions from ICS. This device uses a

26.5625MHz, 18pF parallel resonant crystal to synthesize

106.25MHz. Using FemtoClock’s^TMultra-low phase noise VCO

technology, the ICS840014I can achieve 1ps or lower typical

random rms phase jitter, easily meeting Fibre Channel jitter

requirements. The ICS840014I is packaged in a small 20-pin

TSSOP package.

• RMS phase jitter @ 106.25MHz (637KHz - 5MHz):

0.72ps (typical)

• Output supply modes:

Core/Output

3.3V/3.3V

3.3V/2.5V

2.5V/2.5V

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