SY100EP14U
Micrel
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
in 2.5V, 3.3V, and 5V systems. A V
BB
reference is 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
BB
pin to the unused /CLK pin, and
bypass the pin to V
CC
through a 0.01
μ
F capacitor.
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.
