Unlike standard multiplexers, the SY89837U unique 2:1 runt
pulse eliminator (RPE) input 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 static DC differential
voltage (differential input voltage drops below 200mV).
The SY89837U distributes clock frequencies from 1kHz to
1.5GHz, guaranteed, over temperature and voltage.
The differential input includes Micrel’s unique, 3-pin input
termination architecture that allows customers to interface
to any differential signal (AC- or DC-coupled) as small as
200mV without any level shifting or termination resistor
networks in the signal path. The outputs are 800mV, 100k
compatible LVPECL with fast rise/fall times guaranteed to
be less than 200ps.
The SY89837U operates from a +2.5V±5% or +3.3V±10%
supply and is guaranteed over the full industrial temperature
range of –40°C to +85°C. The SY89837U is part of Micrel’s
high-speed, Precision Edge product line.
