SY89854U  
Precision Low Power 1:4 LVPECL Fanout  
Buffer/Translator with Internal Termination  
General Description  
The SY89854U is a 2.5V/3.3V precision, high-  
speed, fully differential 1:4 LVPECL fanout buffer.  
Optimized to provide four identical output copies  
with less than 20ps of skew and less than 10ps(pp)  
total jitter, the SY89854U can process clock signals  
as fast as 2GHz.

Precision Edge  
Features  
Precision 1:4, LVPECL fanout buffer  
Low power: 137mW (2.5V typ)  
Guaranteed AC performance over temperature  
The differential input includes Micrel’s unique, patent  
pending 3-pin input termination architecture that  
interfaces to any differential signal (AC or DC-  
coupled) as small as 100mV (200mVpp) without any  
level shifting or termination resistor networks in the  
signal path. For AC-coupled input interface  
applications, an on-board output reference voltage  
(VREF-AC) is provided to bias the center-tap (VT)  
pin. The outputs are 800mV LVPECL, with fast  
rise/fall times guaranteed to be less than 180ps.  
and supply voltage:  
– DC- to > 2GHz Clock fMAX  
– <340ps tpd  
– <180ps tr/tf time  
– <20ps max. skew  
Ultra-low jitter design:  
– <1ps(rms) random jitter  
– <10ps(pp) deterministic jitter  
– <10ps(pp) total jitter (clock)  
The SY89854U operates from a 2.5V ±5% supply or  
a 3.3V ±10% supply and is guaranteed over the full  
industrial temperature range of –40°C to +85°C.  
The SY89854U is part of Micrel’s high-speed,  
Unique patent pending input termination and VT  
pin accepts DC-coupled and AC-coupled inputs  
(CML, PECL, LVDS)

Typical 800mV (100k) LVPECL output swing  
Power supply 2.5V ±5% or 3.3V ±10%  
Industrial temperature range –40°C to +85°C  
Available in ultra-small (3mm x 3mm) 16-pin  
MLF™ package  
Typical Applications
