FEMTOCLOCKS™ CRYSTAL-TO-LVDS  
FREQUENCY SYNTHESIZER  
ICS844002  
GENERAL DESCRIPTION  
FEATURES  
The ICS844002 is a 2 output LVDS Synthesizer  
Two LVDS outputs  
ICS  
HiPerClockS™  
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  
• Selectable crystal oscillator interface  
or LVCMOS/LVTTL single-ended input  
• Supports the following output frequencies: 212.5MHz,  
187.5MHz, 159.375MHz, 106.25MHz and 53.125MHz  
parallel resonant crystal, the following frequencies can be  
generated based on the 2 frequency select pins (F_SEL[1:0]):  
212.5MHz, 187.5MHz, 159.375MHz, 106.25MHz and  
53.125MHz. The ICS844002 uses IDT’s 3rd generation low  
phase noise VCO technology and can achieve <1ps typical rms  
phase jitter, easily meeting Fibre Channel jitter requirements.  
The ICS844002 is packaged in a small 20-pin TSSOP package.  
• VCO range: 560MHz - 680MHz  
• RMS phase jitter @ 212.5MHz, using a 26.5625MHz crystal  
(637kHz - 10MHz): 0.65ps (typical)  
• Full 3.3V or 2.5V supply modes  
• 0°C to 70°C ambient operating temperature  
• Available in both standard (RoHS 5) and lead-free (RoHS 6)  
packages
