PRELIMINARY  
FEMTOCLOCKS™ CRYSTAL-TO-0.7V DIFF/LVDS  
FREQUENCY SYNTHESIZER FOR PCI EXPRESS  
ICS841003I-04  
GENERAL DESCRIPTION  
FEATURES  
• Three differential outputs on two banks, Bank A with one  
0.7V DIFF pair and Bank B with two LVDS output pairs  
The ICS841003I-04 is a 3 differential output  
ICS  
Synthesizer designed to generate PCI Express  
or 10 Gigabit reference clock frequencies and is  
a member of the HiPerClocks™ family of high  
performance clock solutions from IDT. Using a  
HiPerClockS™  
• Using a 19.53125MHz, 20MHz, or 25MHz crystal, the two  
output banks can be independently set for 625MHz, 500MHz  
312.5MHz, 250MHz, 156.25MHz, 125MHz or 100MHz  
19.53125MHz, 20MHz or 25MHz, 18pF parallel resonant  
crystal, the following frequencies can be generated based on  
the settings of 4 frequency select pins (DIV_SELA[1:0],  
DIV_SELB[1:0]): 625MHz, 500MHz, 312.5MHz, 250MHz,  
156.25MHz, 125MHz and 100MHz. The 841003I-04 has 2  
output banks, Bank A with one 0.7V DIFF output pair and Bank  
B with two differential LVDS output pairs.  
• Selectable crystal oscillator interface or LVCMOS/LVTTL  
single-ended input  
• VCO range: 490MHz to 680MHz  
• RMS phase jitter @ 125MHz (1.875MHz - 20MHz):  
0.38ps (typical)  
• Full 3.3V supply mode  
The two banks have their own dedicated frequency select pins  
and can be independently set for the frequencies mentioned  
above. The ICS841003I-04 uses IDT’s 3rd generation low phase  
noise VCO technology and can achieve 1ps or lower typical  
rms phase jitter, easily meeting PCI Express jitter requirements.  
The ICS841003I-04 is packaged in a 32-pin VFQFN package.  
• -40°C to 85°C ambient operating temperature  
• Available in both standard (RoHS 5) and lead-free (RoHS 6)  
packages
