FEMTOCLOCK® CRYSTAL-TO-LVDS  
CLOCK GENERATOR  
ICS844251-14  
General Description  
Features  
The ICS844251-14 is an Ethernet Clock Generator. The  
ICS844251-14 uses an 18pF parallel resonant crystal over the  
range of 23.2MHz – 30MHz. For Ethernet applications, a 25MHz  
crystal is used. The device has excellent <1ps phase jitter  
performance, over the 1.875MHz – 20MHz integration range. The  
ICS844251-14 is packaged in a small 8-pin TSSOP, making it  
ideal for use in systems with limited board space.  
One differential LVDS output pair  
Crystal oscillator interface designed for 18pF, parallel resonant  
crystal (23.2MHz – 30MHz)  
Output frequency ranges: 145MHz – 187.5MHz and  
580MHz – 750MHz  
VCO range: 580MHz – 750MHz  
RMS phase jitter at 156.25MHz, using a 25MHz crystal  
(1.875MHz – 20MHz): 0.53ps (typical)  
Full 3.3V or 2.5V output supply modes  
0°C to 70°C ambient operating temperature  
Available in lead-free (RoHS 6) package
