SY89856U  
2GHz, Low-Power, 1:6 LVPECL Fanout Buffer  
with 2:1 Input MUX and Internal Termination  
General Description  
The SY89856U is a 2.5V/3.3V precision, high-  
speed, 1:6 fanout capable of handling clocks up to  
2.0GHz. A differential 2:1 MUX input is included for  
redundant clock switchover applications.  
®
Precision Edge  
Features  
6 ultra-low skew copies of the selected input  
The differential input includes Micrel’s unique, 3-pin  
input termination architecture that allows the device  
to interface 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. The outputs are LVPECL (100k,  
temperature compensated), with extremely fast  
rise/fall times guaranteed to be less than 200ps.  
2:1 MUX input included for clock switchover  
applications  
Low power: 225mW typical (2.5V)  
2.5V to 3.3V supply voltage  
Unique input isolation design minimizes crosstalk  
Guaranteed AC performance over temperature  
and voltage:  
The SY89856U 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  
SY89856U is part of Micrel’s high-speed, Precision  
– Clock frequency range: DC to >2.0GHz  
– <400ps IN-to-OUT tpd  
– <200ps tr/tf times  
®
Edge product line.  
– <30ps skew (output-to-output)  
All support documentation can be found on Micrel’s  
web site at: www.micrel.com.  
Ultra-low jitter design:  
– <1psRMS random jitter  
– <10psPP total jitter (clock)  
– <1psRMS cycle-to-cycle jitter  
– <0.7psRMS crosstalk-induced jitter  
Functional Block Diagram  
Unique input termination and VT pin accepts DC-  
and AC-coupled inputs (CML, PECL, LVDS)  
100k LVPECL compatible output swing  
–40°C to +85°C industrial temperature range  
Available in 32-pin (5mm x 5mm) MLF® package
