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

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

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.
