Datasheet Summary
Precision Low Power 1:4 LVPECL Fanout Buffer/Translator with Internal Termination
General Description
The SY89854U is a 2.5V/3.3V precision, highspeed, fully differential 1:4 LVPECL fanout buffer. Optimized to provide four identical output copies with less than 20ps of skew and less than 10ps(pp) total jitter, the SY89854U can process clock signals as fast as 2GHz. The differential input includes Micrel’s unique, patent pending 3-pin input termination architecture that interfaces to any differential signal (AC or DCcoupled) as small as 100mV (200mVpp) without any level shifting or termination resistor networks in the signal path. For AC-coupled input interface applications, an...
