FemtoClock™ Crystal-to-3.3V LVPECL  
Frequency Synthesizer  
ICS843253I-45  
General Description  
Features  
The ICS843253I-45 is a two LVPECL output and  
one LVCMOS output Synthesizer optimized to  
generate Ethernet reference clock frequencies and  
is a member of the HiPerClocks™ family of high  
performance clock solutions from IDT. Using a  
Two differential LVPECL output pairs and  
S
one LVCMOS reference clock output  
IC  
HiPerClockS™  
Crystal oscillator interface designed for a 25MHz, 18pF parallel  
resonant crystal  
A 25MHz crystal generates output frequencies of: 25MHz,  
25MHz, 18pF parallel resonant crystal, the following frequencies  
can be generated: 25MHz, 125MHz, and 156.25MHz. The  
ICS843253I-45 uses 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 ICS843253I-45 is  
packaged in a small 16-pin TSSOP package.  
125MHz and 156.25MHz  
VCO frequency: 625MHz  
RMS Phase Jitter @ 156.25MHz, (1.875MHz – 20MHz) using a  
25MHz crystal: 0.46ps (typical)  
Full 3.3V supply mode  
-40°C to 85°C ambient operating temperature  
Available in both standard (RoHS 5) and lead-free (RoHS 6)  
packages
