PRELIMINARY DATA SHEET  
General Description  
Features  
The ICS844051 is a Gigabit Ethernet Clock Generator. The  
ICS844051 can synthesize 10 Gigabit Ethernet, SONET, or Serial  
ATA reference clock frequencies with the appropriate choice of  
crystal and output divider. The ICS844051 has excellent phase jitter  
performance and is packaged in a small 8-pin TSSOP, making it  
ideal for use in systems with limited board space.  
One differential LVDS clock output pair  
Crystal interface designed for 18pF parallel resonant crystals  
(18.125MHz – 23.4375MHz)  
Output frequency range: 145MHz – 187.5MHz and  
72.5MHz – 93.75MHz  
VCO range: 580MHz – 750MHz  
RMS phase jitter @ 156.25MHz, (1.875MHz - 20MHz):  
0.45ps (typical)  
Full 3.3V or 2.5V operating supply  
Available in lead-free (RoHS 6) package  
0°C to 70°C ambient operating temperature
