FEMTOCLOCKS™ CRYSTAL-TO-LVDS  
CLOCK GENERATOR  
ICS844031-01  
GENERAL DESCRIPTION  
FEATURES  
One differential LVDS output  
The ICS844031-01 is an Ethernet Clock Generator  
ICS  
HiPerClockS™  
and a member of the HiPerClocksTM family of high  
performance devices from IDT. The ICS844031-01  
uses an 18pF parallel resonant crystal over the  
range of 19.6MHz - 27.2MHz. For Ethernet  
Crystal oscillator interface, 18pF parallel resonant crystal  
(19.6MHz - 27.2MHz)  
Output frequency range: 245MHz - 340MHz  
VCO range: 490MHz - 680MHz  
applications, a 25MHz crystal is used to generate 312.5MHz.  
The ICS844031-01 has excellent <1ps phase jitter performance,  
over the 1.875MHz - 20MHz integration range. The ICS844031-  
01 is packaged in a small 8-pin TSSOP, making it ideal for use  
in systems with limited board space.  
RMS phase jitter @ 312.5MHz, using a 25MHz crystal  
(1.875MHz - 20MHz): 0.53ps (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)
