FEMTOCLOCKS™ CRYSTAL-TO-LVDS  
CLOCK GENERATOR  
ICS844001  
GENERAL DESCRIPTION  
FEATURES  
The ICS844001 is a Fibre Channel Clock Generator. The  
ICS844001 uses an 18pF parallel resonant crystal over the  
range of 20.4MHz - 28.3MHz. For Fibre Channel applications, a  
26.5625MHz crystal is used. The frequency select pin allows  
the device to generate either 106.25MHz or 212.5MHz from a  
26.5625MHz crystal. To generate 187.5MHz for 12Gb Ethernet,  
a 23.4375MHz crystal is used. The ICS844001 uses IDT’s  
3rd generation low phase noise VCO technology and can achieve  
<1ps typical rms phase jitter, easily meeting Fibre Channel and  
Ethernet jitter requirements. The ICS844001 is packaged in a  
small 8-pin TSSOP, making it ideal for use in systems with limited  
board space.  
One Differential LVDS output  
Crystal oscillator interface, 18pF parallel resonant crystal  
(20.4MHz - 28.3MHz)  
Output frequency range: 81.66MHz - 226.66MHz  
VCO range: 490MHz - 680MHz  
RMS phase jitter @ 106.25MHz, using a 26.5625MHz crystal  
(637kHz - 10MHz): 0.74ps (typical)  
3.3V or 2.5V operating supply  
0°C to 70°C ambient operating temperature  
Available in both standard (RoHS 5) and lead-free (RoHS 6)  
packages  
NOTE: It is not recommended to overdrive the crystal input with  
an external clock.
