Description
Max9380 Single-ended-to-differential Lvecl/lvpecl 2 1 Multiplexer
Manufacturer
Maxim Integrated Products, Inc.
Datasheet
The MAX9380 is a high-speed, low-jitter 2:1 multiplexer
for clock and data distribution applications. The device
selects one of the two single-ended inputs and con-
verts it to a differential output.
The MAX9380 features low part-to-part skew of 33ps
and propagation delay of 263ps.
The MAX9380 operates from a +3.0V to +3.8V supply for
LVPECL applications or from a -3.0V to -3.8V supply for
LVECL applications. The input is selected by a single select
input. The select and data inputs feature internal pulldown
resistors that ensure a low default state if left open.
These devices are specified for operation from -40°C to
+85°C, and are available in space-saving 8-pin µMAX
and SO packages.
