DESCRIPTION  
supply voltage:  
„ Wide operating frequency: 1kHz to >1.5GHz  
The SY89837U is a low jitter, low skew, high-speed 1:8  
fanout buffer with a unique, 2:1 differential input multiplexer  
(MUX) optimized for clock redundant switchover applications.  
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.  
„ Unique input termination and VT pin accepts DC- or  
AC-coupled inputs (CML, PECL, LVDS)  
„ 800mV LVPECL output swing  
„ Power supply +2.5V ±5% or +3.3V ±10%  
„ –40°C to +85°C industrial temperature range

„ Available in 32-pin (5mm x 5mm) MLF package  
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.
