DS64BR401 Quad Bi-Directional Repeater with Equalization and  
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 de-  
emphasis 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.

To enable seamless upgrade from SAS/SATA 3.0  
Gbps to 6.0 Gbps data rates without compromising  
physical reach, DS64BR401 automatically detects the  
incoming data rate and selects the optimal de-  
emphasis pulse width. The device detects the out-of-  
band (OOB) idle and active signals of the SAS/SATA  
specification and passes through with minimum signal  
distortion.

With a typical power consumption of 200 mW/lane

unused channels, the DS64BR401 is part of Texas  
Instruments' PowerWise family of energy efficient  
devices.
