PRELIMINARY  
FEMTOCLOCKS™ CRYSTAL-TO-0.7V DIFF/LVDS  
FREQUENCY SYNTHESIZER FOR PCI EXPRESS  
ICS841003I-02  
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-02 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 31.25MHz, 26.041666 or 25MHz crystal, supports  
the following frequencies: 625MHz, 500MHz, 312.5MHz,  
250MHz, 156.25MHz, 125MHz or 100MHz  
31.25MHz, 26.041666MHz 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]): 500MHz, 312.5MHz, 250MHz, 156.25MHz,  
125MHz, and 100MHz. The 841003I-02 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):  
0.54ps (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-02 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-02 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
