GENERAL DESCRIPTION  
FEATURES  
The ICS87004 is a highly versatile 1:4 Differential- • 4 LVCMOS/LVTTL outputs, 7typical output impedance  
ICS  
to-LVCMOS/LVTTL Clock Generator and a mem-  
• Selectable CLK0, nCLK0 or CLK1, nCLK1 clock inputs  
ber of the HiPerClockSfamily of High Perfor-  
HiPerClockS™  
• CLKx, nCLKx pairs can accept the following differential  
input levels: LVPECL, LVDS, LVHSTL, HCSL, SSTL  
mance Clock Solutions from ICS. The ICS87004  
has two selectable clock inputs.The CLK0, nCLK0  
and CLK1, nCLK1 pairs can accept most standard differential  
input levels. Internal bias on the nCLK0 and nCLK1 inputs  
allows the CLK0 and CLK1 inputs to accept LVCMOS/LVTTL.  
The ICS87004 has a fully integrated PLL and can be configured  
as zero delay buffer, multiplier or divider and has an input and  
output frequency range of 15.625MHz to 250MHz. The refer-  
ence 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 exter-  
nal 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.  
• Internal bias on nCLK0 and nCLK1 to support  
LVCMOS/LVTTL levels on CLK0 and CLK1 inputs  
• Output frequency range: 15.625MHz to 250MHz  
• Input frequency range: 15.625MHz to 250MHz  
• VCO range: 250MHz to 500MHz  
• External feedback for “zero delay” clock regeneration  
with configurable frequencies  
• 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  
• Fully integrated PLL  
• Cycle-to-cycle jitter: 45ps (maximum)  
• Output skew: 45ps (maximum)  
• Static phase offset: 50 125ps (ꢀ.ꢀV 5ꢁ)  
• Full ꢀ.ꢀV or 2.5V operating supply  
• 5V tolerant inputs  
• Lead-Free package available  
• Industrial temperature information available upon request
