De-Emphasis
Check for Samples: DS64BR401 FEATURES DESCRIPTION The DS64BR401 is a quad lane bi-directional signal
conditioning repeater for 6.0/3.0/1.5 Gbps SATA/SAS
and other high-speed bus applications with data rates
up to 6.4 Gbps. The device performs both receive
equalization and transmit de-emphasis on each of its
8 channels to compensate for channel loss, 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. This Low Power
Differential Signaling (LPDS) output driver is a power
efficient implementation that maintains compatibility
with AC coupled CML receiver. The programmable
settings can be applied via pin settings or SMBus
interface. 1 2 Quad lane bi-directional repeater up to 6.4 …
