SY89854U - 1:4 LVPECL Fanout Buffer/Translator

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.

Features

  • Precision Edge®.
  • Precision 1:4, LVPECL fanout buffer.
  • Low power: 137mW (2.5V typ).
  • Guaranteed AC performance over temperature and supply voltage:.
  • DC- to > 2GHz Clock fMAX.

SY89854U 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 on-board output reference voltage (VREF-AC) is provided to bias the center-tap (VT) pin.
