The MAX3840 is a dual 2
switch for SDH/SONET DWDM and other high-speed
data switching applications where serial data stream
loop-through and protection channel switching are
required. It is ideal for OC-48 systems with forward
error correction. A high-bandwidth, fully differential sig-
nal path minimizes jitter accumulation, crosstalk, and
signal skew. Each 2
and/or multiplex up to 2.7Gbps data and 2.7GHz clock
signals. All inputs and outputs are current mode logic
(CML) compatible and easily adaptable to interface
with an AC-coupled LVPECL signal. When not used,
each CML output stage can be powered down with an
enable control to conserve power. The typical power
consumption is 460mW with all outputs enabled.
The MAX3840 is compatible with the MAX3876
2.5Gbps clock and data recovery (CDR) circuit.
The MAX3840 is available in a 32-pin exposed-pad
QFN package (5mm
from a +3.3V supply over a temperature range of -40°C
to +85°C.
