SY89845U Precision CML Runt Pulse Eliminator 2:1 MUX With 1:2 Fanout And Internal TerminationThe SY89845U is a low jitter CML, 2:1 differential input multiplexer (MUX) optimized for redundant source switchover applications. Unlike standard multiplexers, the SY89845U 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 the pins of the
differential input drops below 100mV).
The differential input includes Micrels unique, 3-pin input termination architecture that allows customers to Interface to any differential signal (AC- or DCcoupled) as small as 100mV (200mVPP) without any level shifting or termination resistor networks in the signal path. The outputs are 400mV CML with fast
rise/fall times guaranteed to be less than 80ps.
The SY89845U operates from a 2.5V 5% or 3.3V 10% supply and is guaranteed over the full industrial temperature range of 40C to +85C. The SY89845U is part of Micrels high-speed, Precision Edge product line.
