SY89846U  
1.5GHz Precision, LVPECL 1:5 Fanout with 2:1  
MUX and Fail Safe Input with Internal  
Termination  
General Description  
The SY89846U is a 2.5/3.3V, 1:5 LVPECL fanout  
buffer with a 2:1 differential input multiplexer (MUX).  
A unique Fail-Safe Input (FSI) protection prevents  
metastable output conditions when the selected  
input clock fails to a DC voltage (voltage between  
the pins of the differential input drops significantly  
below 100mV).  
Precision Edge®  
Features  
Selects between two inputs, and provides 5 precision  
LVPECL copies  
Fail-Safe Input  
– Prevents outputs from oscillating when input is  
invalid  
Guaranteed AC performance over temperature and  
supply voltage:  
The differential input includes Micrel’s unique, 3-pin  
internal termination architecture that can 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 800mV, LVPECL with fast rise/fall times  
guaranteed to be less than 250ps.  
– DC-to >1.5GHz throughput  
– < 900ps Propagation Delay (IN-to-Q)  
– < 250ps Rise/Fall times  
Ultra-low jitter design:  
The SY89846U 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  
SY89846U is part of Micrel’s high-speed, Precision  
Edge® product line.  
– <1psRMS random jitter  
– <1psRMS cycle-to-cycle jitter  
– <10psPP total jitter (clock)  
– <0.7psRMS MUX crosstalk induced jitter  
Unique, patented MUX input isolation design  
All support documentation can be found on Micrel’s  
web site at: www.micrel.com.  
minimizes adjacent channel crosstalk  
Unique patented internal termination and VT pin  
accepts DC- and AC-coupled inputs (CML, PECL,  
LVDS)  
Functional Block Diagram  
Wide input voltage range. VCC to GND  
2.5V ±5% or 3.3 ±10% supply voltage  
-40°C to +85°C industrial temperature range  
Available in 32-pin (5mm x 5mm) MLF® package  
Applications  
Fail-safe clock protection  
SONET clock distribution  
Backplane distribution
