De-Emphasis
Check for Samples: DS64MB201 FEATURES DESCRIPTION The DS64MB201 is a dual lane 2:1 multiplexer and
1:2 switch or fan-out buffer with signal conditioning
suitable for SATA/SAS and other high-speed bus
applications up to 6.4 Gbps. The device performs
both receive equalization and transmit de-emphasis,
allowing maximum flexibility of physical placement
within a system. The receiver's continuous time linear
equalizer (CTLE) provides a boost of up to +33 dB at
3 GHz and 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 output deemphasis driver and allows amplitude voltage levels
to be selected from 600 mVp-p to 1200 mVp-p to suit
multiple application scenarios. The signal conditioning
settings are programmable via control pin settings or
SMBus interface. 1 2 Up to 6.4 Gbps dual lane 2:1 mux, 1:2 switch
