SY89474U  
Precision LVDS 2:1 Multiplexer with 1:2  
Fanout and Internal Termination  
General Description  
The SY89474U is a 2.5V precision, high-speed 2:1  
differential MUX capable of processing clocks up to  
2.5GHz and data up to 2.5Gbps.  
®
Precision Edge  
Features  
The differential input includes Micrel’s unique, 3-pin input  
termination architecture that directly 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. The  
output is 325mV LVDS with fast rise/fall times guaranteed  
to be less than 150ps.  
Selects between two input channels and provides two  
copies of the selected input  
Guaranteed AC performance over temperature and  
supply voltage:  
DC to 2.5Gbps data throughput  
DC to 2.5GHz fMAX (clock)  
<470ps In-to-Out tpd  
<150ps tr/tf  
The SY89474U operates from a 2.5V ±5% supply and is  
guaranteed over the full industrial temperature range of  
-40°C to +85°C. The SY89474U is part of Micrel’s high-  
speed, Precision Edge® product line. For multiple clock  
switchover solutions, please refer to the SY89840U–  
SY89845U family.  
<20ps output-to-output skew  
Unique, patent-pending input isolation design  
minimizes crosstalk  
Ultra-low jitter design:  
All support documentation can be found on Micrel’s web  
site at: www.micrel.com.  
<1psRMS random jitter  
<10psPP deterministic jitter  
<1psRMS cycle-to-cycle jitter  
<10psPP total jitter (clock)  
<0.7psRMS crosstalk induced jitter  
Functional Block Diagram  
Unique patent-pending input termination and VT pin  
accepts DC- and AC-coupled inputs (CML, PECL,  
LVDS)  
325mV LVDS output swing  
2.5V ±5% supply voltage  
40°C to +85°C industrial temperature range  
Available in 24-pin (4mm x 4mm) QFN package
