DESCRIPTION
The DS100MB201 is a dual lane 2:1 multiplexer and
1:2 switch or fan-out buffer with signal conditioning
suitable for 10GE, Fibre Channel, Infiniband,
SATA/SAS and other high-speed bus applications up
to 10.31215 Gbps. The device performs receive
equalization allowing maximum flexibility of physical
placement within a system. The receiver's continuous
time linear equalizer (CTLE) provides a boost to
compensate for 10” of 4 mil FR4 stripline at 10.3125
Gbps. The DS100MB201 is capable of opening an
input eye that is completely closed due to inter•
symbol interference (ISI) induced by the interconnect
medium. The transmitter features a programmable
amplitude voltage levels to be selected from 600
mVp-p to 800 mVp-p. The signal conditioning settings
are programmable with register control.
With a typical power consumption of 100 mW/channel
at 10.3125 Gbps, and SMBus register control to turn
off unused lanes, the DS100MB201 is part of TI's
PowerWise family of energy efficient devices.
