SY89840U Datasheet (Micrel Semiconductor) - Precision LVPECL Runt Pulse Eliminator 2:1 Multiplexer

SY89840U, Precision LVPECL Runt Pulse Eliminator 2:1 Multiplexer

The SY89840U is a low jitter PECL, 2:1 differential input multiplexer (MUX) optimized for redundant source switchover applications.

Unlike standard multiplexers, the SY89840U unique 2:1 Runt Pulse Eliminator (RPE) MUX prevents any short cycles or “runt” pulses during switchover.

In addition, a uniqu
