General Description

The SY100EP14AU 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 in 2.5V and 3.3V systems. A V

included 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

and bypass the pin to V

The SY100EP14AU features a 2:1 input MUX, making it

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 SY100EP14AU I/O are fully differential and 100K ECL

compatible. Differential 10K ECL logic can interface

directly into the SY100EP14AU inputs.

The SY100EP14AU 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.
