ICS843252-45  
3.3V LVPECL FREQUENCY SYNTHESIZER  
General Description  
Features  
The ICS843252-45 is a 2 LVPECL 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 25MHz, 18pF parallel  
Two differential LVPECL output pairs  
S
IC  
Crystal oscillator interface designed for a 25MHz, 18pF parallel  
HiPerClockS™  
resonant crystal  
A 25MHz crystal generates output frequencies of: 156.25MHz  
and 125MHz  
resonant crystal, the following frequencies can be generated:  
156.25MHz and 125MHz. The ICS843252-45 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 ICS843252-45 is packaged in a small 16-pin  
TSSOP package.  
VCO frequency: 625MHz  
RMS Phase Jitter @ 156.25MHz, (1.875MHz – 20MHz) using a  
25MHz crystal: 0.54ps (typical)  
Full 3.3V supply mode  
0°C to 70°C ambient operating temperature  
Available in both standard (RoHS 5) and lead-free (RoHS 6)  
packages
