NB7NPQ7041M  
3.3 V USB 3.1 Quad  
Channel / Dual Port Linear  
Redriver  
Description  
The NB7NPQ7041M is a 3.3 V quad channel / dual port linear  
redriver suitable for USB 3.1 Gen 1 and USB 3.1 Gen 2 applications  
that supports both 5 Gbps and 10 Gbps data rates. Signal integrity  
degrades from PCB traces, transmission cables, and inter−symbol  
interference (ISI). The NB7NPQ7041M compensates for these losses  
by engaging varying levels of equalization at the input receiver, and flat  
gain amplification on the output transmitter. The Flat Gain and  
Equalization are controlled by four level control pins. Each channel has  
a set of independent control pins to make signal optimization possible.  
After power up, the NB7NPQ7041M periodically checks both of the  
TX output pairs of each port for a receiver connection. When the receiver  
is detected on both channels, the RX termination becomes enabled of  
that respective port and is set to perform the redriver function.  
The port becomes active once both TX outputs have detected  
50−ohm termination, and the NB7NPQ7041M is set to perform the  
redriver function. Port AB (channels A & B) and port CD (channels C  
& D) are independent of each other.

APPLICATION GUIDELINES  
LFPS Compliance Testing  
bias the control pins to the correct voltage to achieve this if  
the pin is not connected to a voltage source. The low Setting  
“L” is set by pulling the control pin to ground. Likewise the  
high setting “H” is set by pulling the pin high to VCC. The  
Rexternal setting can be set by adding a 68−K resistor from the  
control pin to ground. This will bias the Redriver internal  
voltage to 33% of VCC.  
As part of USB 3.1 compliance test, the host or peripheral  
must transmit a LFPS signal that adheres to the spec  
parameters. The NB7NPQ7041M is tested as a part of a USB  
compliant system to ensure that it maintains compliance  
while increasing system performance.  
LFPS Functionality  
USB 3.1, Gen1 and Gen2 use Low Frequency Periodic  
Signaling.  
Linear Equalization  
The linear equalization that the NB7NPQ7041M provides  
compensates for losses that occur naturally along board  
traces and cable lines. Linear Equalization boosts high  
frequencies and lower frequencies linearly so when  
transmitting at varying frequencies, the voltage amplitude  
will remain consistent. This compensation electrically  
counters losses and allows for longer traces to be possible  
when routing.  
(LFPS) to implement functions like exiting low−power  
modes, performing warm resets and providing link training  
between host and peripheral devices. LFPS signaling  
consists of bursts of frequencies ranging between 10 to  
50 MHz and can have specific burst lengths or repeat rates.  
Ping.LFPS for TX Compliance  
During the transmitter compliance, the system under test  
must transmit certain compliance patterns as defined by the  
USB−IF. In order to toggle through these patterns for various  
tests, the receiver must receive a ping.LFPS signal from  
either the test suite or a separate pattern generator. The  
standard signal comprises of a single burst period of 100 ns  
at 20 MHz.  
DC Flat Gain  
DC flat gain equally boosts high and low frequency  
signals, and is essential for countering low frequency losses.  
DC flat gain can also be used to simulate a higher input  
signal from a USB Controller. If a USB controller can only  
provide 800 mV differential to a receiver, it can be boosted  
to 1128 mV using 3 dB of flat gain.  
Control Pin Settings  
Control pins A1, A0, B1, and B0 control the Flat Gain and  
the Equalization of channels A and B and control pins C1,  
C0, D1, and D0 control the Flat Gain and the Equalization  
of channels C and D of the NB7NPQ7041M Device.  
The Float (Default) Setting “F” can be set by leaving the  
control pins in a floating state. The Redriver will internally  
Total Gain  
When using Flat Gain with Equalization in a USB  
application it is important to make sure that the total voltage  
does not exceed 1200 mV. Total gain can be calculated by  
adding the EQ gain to the FG.

9. Trace loss of FR4 was estimated to have 1 dB of loss per 1 inch of FR4 length with matched impedance and no VIAS.  
Typical Layout Practices  
RX and TX differential pairs should always be placed  
RX and TX pairs should maintain as close to a 90 W  
differential impedance as possible.  
Limit the number of vias used on each data line. It is  
suggested that 2 or fewer are used.  
and routed on the same layer directly above a ground  
plane. This will help reduce EMI and noise on the data  
lines.  
Routing angles should be obtuse angles and kept to 135  
degrees or larger.  
Traces should be routed as straight and symmetric as  
possible.  
To minimize crosstalk, TX and RX data lines should be  
kept away from other high speed signals.
