ICS8735I-31  
1:5 DIFFERENTIAL-TO-3.3V LVPECL  
ZERO DELAY CLOCK GENERATOR  
Integrated  
Circuit  
Systems, Inc.  
GENERAL DESCRIPTION  
FEATURES  
The ICS8735I-31 is a highly versatile 1:5 Differ- 5 differential 3.3V LVPECL outputs  
ICS  
ential-to-3.3V LVPECL Clock Generator and a  
Selectable differential clock inputs  
HiPerClockS™  
member of the HiPerClockS™ family of High Per-  
formance Clock Solutions from ICS. The  
ICS8735I-31 has a fully integrated PLL and can  
CLKx, nCLKx pair can accept the following differential  
input levels: LVPECL, LVDS, LVHSTL, SSTL, HCSL  
be configured as zero delay buffer, multiplier or divider, and  
has an output frequency range of 15.625MHz to 350MHz.The  
reference divider, feedback divider and output divider are each  
programmable, thereby allowing for the following output-to-  
input frequency ratios: 8:1, 4:1, 2:1, 1:1, 1:2, 1:4, 1:8. The  
external feedback allows the device to achieve “zero delay”  
between the input clock and the output clocks.The PLL_SEL  
pin can be used to bypass the PLL for system test and debug  
purposes. In bypass mode, the reference clock is routed  
around the PLL and into the internal output dividers.  
Output frequency range: 15.625MHz to 350MHz  
Input frequency range: 15.625MHz to 350MHz  
VCO range: 250MHz to 700MHz  
Programmable dividers allow for the following output-to-input  
frequency ratios: 8:1, 4:1, 2:1, 1:1, 1:2, 1:4, 1:8  
External feedback for “zero delay” clock regeneration  
with configurable frequencies  
Cycle-to-cycle jitter: 60ps (maximum)  
Output skew: 35ps (maximum)  
Static phase offset: 55ps 125ps  
3.3V supply voltage  
-40°C to 85°C ambient operating temperature  
Lead-Free package fully RoHS compliant
