Overview
Description
The 854S204I is a low skew, high performance dual, programmable 1-to-2 Differential-to-LVDS, LVPECL Fanout Buffer. The PCLKx, nPCLKx pairs can accept most standard differential input levels. With the selection of SEL_OUT signal, outputs can be selected be to either LVDS or LVPECL levels. The 854S204I is characterized to operate from either a 2.5V or a 3.3V power supply. Guaranteed output and bank skew characteristics make the 854S204I ideal for those clock distribution applications demanding well defined performance and repeatability.
