ICS840002I

FEMTOCLOCKS™ CRYSTAL-TO-

LVCMOS/LVTTL FREQUENCY SYNTHESIZER

Integrated

Circuit

Systems, Inc.

GENERAL DESCRIPTION

FEATURES

• Two LVCMOS outputs @ 3.3V, 17Ω typical output impedance

The ICS840002I is a 2 output LVCMOS/LVTTL

ICS

Synthesizer optimized to generate Fibre Channel

reference clock frequencies and is a member of

the HiPerClocks^TMfamily of high performance

clock solutions from ICS. Using a 26.5625MHz

• Selectable crystal oscillator interface

or LVCMOS single-ended input

HiPerClockS™

• Output frequency range: 46.66MHz - 233.33MHz

• VCO range: 560MHz - 700MHz

18pF parallel resonant crystal, the following frequencies can be

generated based on the 2 frequency select pins (F_SEL1:0):

212.5MHz, 159.375MHz, 156.25MHz, 106.25MHz, and

53.125MHz.The ICS840002I uses ICS’3^rdgeneration low phase

noise VCO technology and can achieve 1ps or lower typical

rms phase jitter, easily meeting Fibre Channel jitter requirements.

The ICS840002I is packaged in a 16-pin TSSOP package.

• Supports the following output frequencies: 212.5MHz,

159.375MHz, 156.25MHz, 106.25MHz and 53.125MHz

• RMS phase jitter @ 212.5MHz (637KHz - 10MHz):

0.83ps (typical)

Typical phase noise at 212.5MHz:

Offset

Noise Power

100Hz ............... -91.3 dBc/Hz

1KHz ..............-114.3 dBc/Hz

10KHz ..............-120.7 dBc/Hz

100KHz ..............-120.2 dBc/Hz

• Power supply modes:

Core/Output

3.3V/3.3V

3.3V/2.5V

2.5V/2.5V

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

• Lead-Free package RoHS compliant
