Description: Precision LVPECL Runt Pulse Eliminator 2:1 MUX

Features

* Precision Edge ®
* Selects between two sources, and provides a glitch-free, stable LVPECL output
* Guaranteed AC performance over temperature and supply voltage:
* Wide operating frequency: 1kHz to >1.5GHz
* < 880ps In-to-Out tpd
* < 190ps tr/tf

Applications

* Unlike standard multiplexers, the SY89843U unique 2:1 Runt Pulse Eliminator (RPE) MUX prevents any short cycles or “runt” pulses during switchover. In addition, a unique Fail-Safe Input protection prevents metastable conditions when the selected input clock fails to a DC voltage (voltage between th
