LOW SKEW, 1-to-4 LVCMOS/LVTTL-TO-
3.3V LVPECL FANOUT BUFFER

IDT
G
single ended clock input accepts LVCMOS or LVTTL input lev-
els and translate them to 3.3V LVPECL levels. The clock en-
able is internally synchronized to eliminate runt clock pulses
on the output during asynchronous assertion/deassertion of
the clock enable pin.
Guaranteed output and part-to-part skew characteristics make
the ICS8535-01 ideal for those applications demanding well
defined performance and repeatability.
