Description:

Precision LVPECL 1:10 Fanout

Features

* Precision Edge®
* Selects between two sources, and provides 10 precision LVPECL copies
* Guaranteed AC performance over temperature and supply voltage:
* Wide operating frequency: 1kHz to >1.5GHz
* < 1100ps In-to-Out tpd
* < 220ps tr/tf
* Unique, pa

Applications

* Unlike standard multiplexers, the SY89464U’s unique 2:1 Runt Pulse Eliminator (RPE) MUX prevents any short cycles or “runt” pulses during switchover. In addition, a unique FailSafe Input (FSI) protection prevents metastable output conditions when the selected input clock fails to a DC voltage (volt
