PI90LV211/PI90LVT211  
1:6 Differential Clock Distribution Chip  
Description  
Features  
ThePI90LV211implementslowvoltagedifferentialsignaling(LVDS)  
to achieve clocking rates as high as 320 MHz with low skew. The  
PI90LV211isalowskew1:6fanoutdevicedesignedexplicitlyforlow  
skew clock distribution applications. The device features a multi-  
plexedclockinputtoallowforthedistributionofalowerspeedscan  
ortestclockwiththehigh-speedsystemclock.WhenLOW theSEL  
pin will select the differential clock input.  
Both a common enable and individual output enables are provided.  
WhenassertedthepositiveoutputwillgoLOWonthenextnegative  
transition of the CLK (or SCLK) input. The enable function is  
synchronoussothattheoutputswillonlybeenabled/disabledwhen  
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. The internal flip flop  
is clocked on the falling edge of the input clock, therefore all  
associated specification limits are referenced to the negative edge  
of the clock input.  
• MeetsorExceedsRequirementsofANSITIA/EIA-644-1995  
• Designed for Clocking Rates up to 320MHz  
Operates from a single 3.3-V Supply
