General Description
The ICS8535I-21 is a low skew, high performance
1-to-2 LVCMOS/LVTTL-to-3.3V LVPECL fanout
buffer and a member of the HiPerClockS™ family of
High Performance Clock Solutions from IDT. The
ICS8535I-21 has two single-ended clock inputs. The
single-ended clock input accepts LVCMOS or LVTTL input levels
and translate them to 3.3V LVPECL levels. The clock enable 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
ICS8535I-21 ideal for those applications demanding well defined
performance and repeatability.
