General Description
The MAX3640 is a dual-path crosspoint switch for use
at OC-12 data rates. The MAX3640 can be used to
receive and transmit 622Mbps low-voltage differential
signals (LVDS) across a backplane with minimum jitter
accumulation. Each path incorporates input buffers,
multiplexers, a crosspoint switch, and output drivers.
The four output channels have a redundant set of out-
puts for test or fanning purposes. The device offers sig-
nal-path redundancy for critical data streams.
The MAX3640 has a unique power-saving feature.
When a set of four output channels has been de-select-
ed, the output drivers are powered down to reduce
power consumption by 165mW. The fully differential
architecture ensures low crosstalk, jitter accumulation,
and signal skew.
The MAX3640 is available in a 48-pin TQFP package
and operates from a +3.3V supply over the 0°C to
+85°C temperature range.
