PI90LV14/PI90LVT14  
1:5 Clock Distribution  
Features  
Description  
• Meets and Exceeds the Requirements of ANSI  
TIA/EIA-644-1995  
ThePI90LV14implementslowvoltagedifferentialsignaling(LVDS)  
to achieve clocking rates as high as 320MHz with low skew.  
• Designed for clocking rates up to 320MHz  
• Operates from a single 3.3V Supply  
The PI90LV14 is a low-skew 1:5 clock distribution chip which  
incorporates multiplexed clock inputs to allow for distribution of a  
lower-speed, single-ended clock or a high-speed system clock.  
When LOWthe SEL pin will select the differential clock input.  
• LowVoltageDifferentialSignaling(LVDS)withOutput  
Voltagesof±350mVintoa100-ohmload  
• Choice between LVDS or TTL clock input  
• Synchronous Enable/Disable  
The common enable (EN) is synchronous so that the outputs will  
only be enabled/disabled when they are already in the LOW state.  
This avoids any chance of generating a runt clock pulse when the  
device is enabled/disabled as can happen with an asynchronous  
control.Becausetheinternalflip-flopisclockedonthefallingedge  
oftheinputclock, allassociatedspecificationlimitsarereferenced  
to the negative edge of the clock input.  
• Clock outputs default LOW when inputs open  
• Multiplexedclockinput  
– Internal 300kohms pullup resistor on input pins  
CLK&CLKhave110-ohminternaltermination(PI90LVT14)  
• 50ps Output-to-Output Skew  
• 475ps typical propagation delay  
• ±22psPeriodJitter  
The intended application of these devices and signaling technique  
is for high-speed clock distribution between boards.  
• Bus Pins are high impedance when disabled or with V less

than1.5V  
• TTL inputs are 5V Tolerant  
• Power Dissipation at 400Mbits/s of 150mW
