SY89473U  
Precision LVPECL 2:1 Multiplexer with 1:2  
Fanout and Internal Termination  
General Description  
The SY89473U is a 2.5V/3.3V precision, high-speed 2:1  
differential MUX capable of processing clocks up to  
2.5GHz and data up to 2.5Gbps.  
®
Precision Edge  
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 800mV, 100K-compatible, LVPECL with fast  
rise/fall times guaranteed to be less than 190ps.  
Features  
Selects between two input channels and provides two  
copies of the selected output  
Guaranteed AC performance over temperature and  
supply voltage:  
- DC to 2.5Gbps data throughput  
- DC to 2.5GHz fMAX (clock)  
- <500ps In-to-Out tpd  
- <190ps tr/tf  
The SY89473U 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 SY89473U is  
part of Micrel’s high-speed, Precision Edge® product  
line. For multiple-clock switchover solutions, please refer  
to the SY89840–SY89843U family.  
- <20ps Output-to-output skew  
Unique patented input isolation design minimizes  
crosstalk  
All support documentation can be found on Micrel’s web  
site at: www.micrel.com.  
Ultra-low Jitter Design:  
- <1psRMS random 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)  
800mV (100K) LVPECL output swing  
2.5V ±5% or 3.3V ±10% supply voltage  
-40°C to +85°C industrial temperature range  
Available in 24-pin (4mm x 4mm) QFN package
