Low Skew, 1-to-2, Differential-to-2.5V, 3.3V
LVPECL/ ECL Fanout Buffer
853S011B
Datasheet
General Description
The 853S011B is a low skew, high performance 1-to-2
Differential-to-2.5V/3.3V LVPECL/ECL Fanout Buffer. The
853S011B is characterized to operate from either a 2.5V or a 3.3V
power supply. Guaranteed output and part-to-part skew
characteristics make the 853S011B ideal for those clock distribution
applications demanding well defined performance and repeatability.

Two differential 2.5V, 3.3V LVPECL/ECL outputs
One differential PCLK, nPCLK input pair
PCLK, nPCLK pairs can accept the following
differential input levels: LVPECL, LVDS, CML, SSTL
Maximum output frequency: >2.5GHz
Translates any single-ended input signal to 3.3V LVPECL levels
with resistor bias on nPCLK input
Output skew: 5ps (typical)
Part-to-part skew: 130ps (maximum)
Propagation delay: 355ps (maximum)
