PRELIMINARY  
ICS844004I  
FEMTOCLOCKS™ CRYSTAL-TO-  
LVDS FREQUENCY SYNTHESIZER  
Integrated  
Circuit  
Systems, Inc.  
GENERAL DESCRIPTION  
FEATURES  
The ICS844004I is a 4 output LVDS Synthesizer • Four LVDS outputs  
optimized to generate Fibre Channel reference  
ICS  
• Selectable crystal oscillator interface  
or LVCMOS/LVTTL single-ended input  
HiPerClockS™  
clock frequencies and is a member of the  
HiPerClocksTM family of high performance clock  
solutions from ICS. Using a 26.5625MHz 18pF  
• Supports the following output frequencies: 212.5MHz,  
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, 156.25MHz, 106.25MHz  
and 53.125MHz. The ICS844004I uses ICS’ 3rd generation  
low phase noise VCO technology and can achieve <1ps  
typical rms phase jitter, easily meeting Fibre Channel jitter  
requirements. The ICS844004I is packaged in a small 24-pin  
TSSOP package.  
187.5MHz, 159.375MHz, 156.25MHz, 106.25MHz, 53.125MHz  
• 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  
• -40°C to 85°C ambient operating temperature
