SY89847U  
1.5GHz Precision, LVDS 1:5 Fanout with 2:1  
MUX and Fail Safe Input with Internal  
Termination  
General Description  
The SY89847U is a 2.5V, 1:5 LVDS 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 sources, and provides 5  
precision LVDS copies  
Fail-Safe Input  
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 LVDS compatible with very fast rise/fall  
times guaranteed to be less than 210ps.  
Prevents outputs from oscillating when input is  
invalid  
Guaranteed AC performance over temperature and  
supply voltage:  
DC-to >1.5GHz throughput  
<1000ps Propagation Delay (IN-to-Q)  
<210ps Rise/Fall times  
The SY89847U operates from a 2.5V ±5% supply  
and is guaranteed over the full industrial  
temperature range of 40°C to +85°C. The  
SY89847U is part of Micrel’s high-speed, Precision  
Edge® product line.  
Ultra-low jitter design:  
150fs RMS phase jitter (Typ)  
0.7psRMS MUX crosstalk induced jitter  
Unique, patented MUX input isolation design  
minimizes adjacent channel crosstalk  
All support documentation can be found on Micrel’s  
web site at: www.micrel.com.  
Unique, patented internal termination and VT pin  
accepts DC- and AC-coupled inputs (CML, PECL,  
LVDS)  
Wide input voltage range VCC to GND  
2.5V ±5% supply voltage  
Functional Block Diagram  
-40°C to +85°C industrial temperature range  
Available in 32-pin (5mm x 5mm) QFN package  
Applications  
Fail-safe clock protection  
Ultra-low jitter LVDS clock distribution
