DESCRIPTION  
2:1 Differential MUX input  
The SY100EP14U is a high-speed, 2GHz differential  
PECL/ECL 1:5 fanout buffer optimized for ultra-low skew  
applications. Within device skew is guaranteed to be less  
than 25ps over temperature and supply voltage. The wide  
supply voltage operation allows this fanout buffer to operate  
Flexible supply voltage: 2.5V/3.3V/5V  
Wide operating temperature range: –40°C to +85°C

BB  
reference for single-ended or AC-coupled  
PECL inputs  
in 2.5V, 3.3V, and 5V systems. A V reference is included  
BB  
100K ECL compatible outputs  
Inputs accept PECL/LVPECL/ECL/HSTL logic  
75kinternal input pull-down resistors  
Available in a 20-Pin TSSOP package  
for single-supply or AC-coupled PECL/ECL input  
applications, thus eliminating resistor networks. When  
interfacing to a single-ended or AC-coupled PECL/ECL input  
signal, connect the V  
pin to the unused /CLK pin, and  
BB  
bypass the pin to V through a 0.01µF capacitor.  
CC  
The SY100EP14U features a 2:1 input MUX, making it  
an ideal solution for redundant clock switchover applications.  
If only one input pair is used, the other pair may be left  
floating. In addition, this device includes a synchronous  
enable pin that forces the outputs into a fixed logic state.  
Enable or disable state is initiated only after the outputs are  
in a LOW state, thus eliminating the possibility of a “runt”  
clock pulse.  
The SY100EP14U I/O are fully differential and 100K ECL  
compatible. Differential 10K ECL logic can interface directly  
into the SY100EP14U inputs.  
The SY100EP14U is part of Micrel’s high-speed clock  
synchronization family. For applications that require a  
different I/O combination, consult the Micrel website at  
www.micrel.com, and choose from a comprehensive product  
line of high-speed, low-skew fanout buffers, translators, and  
clock generators.
