DATA SHEET
General Description
The 853S111B is a low skew, high performance 1-to-10
Differential-to-2.5V/ 3.3V LVPECL/ECL Fanout Buffer. The
853S111B 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 853S111B ideal for those clock distribution
applications demanding well defined performance and repeatability.
