FemtoClock™ Crystal-to-3.3V  
LVPECL Frequency Synthesizer  
ICS843004-125  
ADVANCE INFORMATION  
DATA SHEET  
GENERAL DESCRIPTION  
FEATURES  
The ICS843004-125 is a 4 output LVPECL Syn-  
thesizer optimized to generate Ethernet reference  
clock frequencies and is a member of the  
HiPerClocksTM family of high performance clock  
solutions from IDT. The ICS843004-125 uses  
• Four 3.3V LVPECL output pairs  
ICS  
HiPerClockS™  
• Selectable crystal oscillator interface  
or LVCMOS/LVTTL single-ended input  
• Crystal oscillator designed for 25MHz, 18pF parallel resonant  
crystal  
IDT’s 3rd generation low phase noise VCO technology and can  
achieve 1ps or lower typical rms phase jitter, easily meeting  
Ethernet jitter requirements. The ICS843004-125 is packaged  
in a small 24-pin TSSOP package.  
• Supports the following output frequency: 125MHz  
• VCO range: 560MHz - 680MHz  
• RMS phase jitter @ 125MHz, using a 25MHz crystal  
(1.875MHz - 20MHz): 0.58ps (typical)  
• Full 3.3V supply mode  
• 0°C to 70°C ambient operating temperature  
• Available in lead-free (RoHS 6) package
