FEMTOCLOCKS™ 1:5, CRYSTAL-TO-

LVCMOS/LVTTL FREQUENCY SYNTHESIZER

ICS840245I

GENERAL DESCRIPTION

FEATURES

• Five LVCMOS outputs, 15Ω typical output impedance

The ICS840245I is a low skew, 1-to-5 LVCMOS/

ICS

LVTTL SATA/SAS Clock Generator and is a mem-

ber of the HiPerClocks^TMfamily of high performance

clock solutions from IDT. The ICS840245I can syn-

thesize 75MHz reference clock frequencies with a

• Crystal oscillator interface

HiPerClockS™

• Supports the following output frequency: 75MHz

• Output skew: 25ps (typical)

25MHz crystal. Each of the 5 outputs on the ICS840245I can

drive two series terminated 50Ω transmission lines, effectively

making the ICS840245I a 1-to-10 clock generator. An output

enable (OE) pin, which controls only the Q4 output, allows the

application to use Q4 as an optional output (for example, test

output pin). The ICS840245I uses IDT’s 3^rdgeneration low phase

noise VCO technology and can achieve 1ps or lower typical

random rms phase jitter. The ICS840245I is packaged in a

16-pin TSSOP package.

• RMS phase jitter @ 75MHz (900kHz - 7.5MHz):

0.454ps (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

• Available in both standard (RoHS 5) and lead-free (RoHS 6)

packages
