SY89464U Precision LVPECL 1:10 Fanout with 2:1 Runt Pulse Eliminator MUX and Internal Termination General Description The SY89464U is a low jitter 1:10 LVPECL fanout buffer with a 2:1 differential input multiplexer (MUX) optimized for redundant source switchover 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 (voltage between the pins of the differential input drops below 100mV).
The differential input includes Micrel’s unique, 3-pin i...
