PRELIMINARY  
FEMTOCLOCKS™ CRYSTAL-TO-  
3.3V LVPECL CLOCK GENERATOR  
ICS843251I-04  
GENERAL DESCRIPTION  
FEATURES  
The ICS843251I-04 is a 10Gb/12Gb Ethernet Clock  
• One differential 3.3V LVPECL output  
ICS  
HiPerClockS™  
Generator and a member of the HiPerClocksTM family  
of high performance devices from IDT. The  
ICS843251I-04 can synthesize 10 Gigabit Ethernet  
and 12 Gigabit Ethernet with a 25MHz crystal. It  
• Crystal oscillator interface designed for  
18pF parallel resonant crystals  
• Crystal input frequency range: 19.33MHz - 30MHz  
• Output frequency range: 145MHz - 187.5MHz  
• VCO frequency range: 580MHz - 750MHz  
can also generate SATA and 10Gb Fibre Channel reference  
clock frequencies with the appropriate choice of crystals. The  
ICS843251I-04 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.  
• RMS phase jitter at 156.25MHz (1.875MHz - 20MHz):  
0.39ps (typical)  
• 3.3V operating supply  
• -40°C to 85°C ambient operating temperature  
• Available in both standard (RoHS 5) and lead-free (RoHS 6)
