General Description
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.
