ICS8705I  
NRND  
Zero Delay, Differential-to-LVCMOS/  
LVTTL Clock Generator  
NOT RECOMMENDED FOR NEW DESIGNS  
GENERAL DESCRIPTION  
FEATURES  
The ICS8705I is a highly versatile 1:8 Differential-to- • Eight LVCMOS/LVTTL outputs, 7Ω typical output impedance  
LVCMOS/LVTTL Clock Generator. The ICS8705I has two  
selectable clock inputs. The CLK1, nCLK1 pair can accept  
most standard differential input levels. The single ended  
CLK0 input accepts LVCMOS or LVTTL input levels.The  
• Selectable CLK1, nCLK1 or LVCMOS/LVTTL clock inputs  
• CLK1, nCLK1 pair can accept the following differential  
input levels: LVPECL, LVDS, LVHSTL, HCSL, SSTL  
• CLK0 input accepts LVCMOS or LVTTL input levels  
• Output frequency range: 15.625MHz to 250MHz  
• Input frequency range: 15.625MHz to 250MHz  
• VCO range: 250MHz to 500MHz  
ICS8705I 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  
reference divider, feedback divider and output divider are  
each programmable, thereby allowing for the following out-  
put-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.  
• 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: CLK0, 65ps (maximum)  
CLK1, nCLK1, 55ps (maximum)  
• Static Phase Offset: 25 125ps (maximum), CLK0  
• Full 3.3V or 2.5V operating supply  
• Lead-Free package available  
• -40°C to 85°C ambient operating temperature  
• Not Recommended for New Designs
