General Description
The ICS8546-01 is a low skew, high performance 1-to-6 Crystal
Oscillator-to-LVDS Fanout Buffer. The ICS8546-01 has selectable
crystal, single ended or differential clock inputs. The single-ended
clock input accepts LVCMOS or LVTTL input levels and translate
them to LVDS levels. The CLK1, nCLK1 pair can accept most
standard differential input levels. The output enable is internally
synchronized to eliminate runt pulses on the outputs during
asynchronous assertion/ deassertion of the clock enable pin.
Guaranteed output and part-to-part skew characteristics make the
ICS8546-01 ideal for those applications demanding well defined
performance and repeatability.
