FEMTOCLOCKS™ LVCMOS/CRYSTAL-TO-  
3.3V LVPECL FREQUENCY SYNTHESIZER  
ICS843004  
General Description  
Features  
The ICS843004 is a 4 output LVPECL synthesizer  
Four 3.3Vdifferential LVPECL output pairs  
S
IC  
optimized to generate Fibre Channel reference clock  
frequencies and is a member of the HiPerClocksTM  
family of high performance clock solutions from IDT.  
Using a 26.5625MHz 18pF parallel resonant crystal,  
Selectable crystal oscillator interface  
HiPerClockS™  
or LVCMOS/LVTTL single-ended clock input  
Supports the following output frequencies: 212.5MHz,  
187.5MHz, 159.375MHz, 156.25MHz, 106.25MHz, 53.125MHz  
the following frequencies can be generated based on the 2  
frequency select pins (F_SEL[1:0]): 212.5MHz, 187.5MHz,  
159.375MHz, 156.25, 106.25MHz, and 53.125MHz. The  
ICS843004 uses IDT’s 3rd generation low phase noise VCO  
technology and can achieve 1ps or lower typical rms phase jitter,  
easily meeting Fibre Channel jitter requirements. The ICS843004  
is packaged in a small 24-pin TSSOP package.  
VCO range: 560MHz – 680MHz  
RMS phase jitter @ 212.5MHz, using a 26.5625MHz crystal  
(637kHz – 10MHz): 0.72ps (typical)  
Offset  
Noise Power  
100Hz................ -95.0 dBc/Hz

Full 3.3V supply mode  
-30°C to 85°C ambient operating temperature  
Available in both standard (RoHS 5) and lead-free (RoHS 6)
