The NB7NPQ7021M is a 3.3 V dual channel, linear redriver for USB 3.1 applications that supports both 5 and 10 Gbps data rates. Signal integrity degrades from PCB
traces and transmission cables which may cause inter-symbol interference (ISI). The NB7NPQ7021M compensates for these losses by engaging varying levels of equalization at the input receiver. The output transmitter circuitry provides user selectable flat gain settings to create the best eye openings for the outgoing data signals. The flexibility of this part allows it to fit into many system applications.
After power up, the NB7NPQ7021M periodically checks both of the TX output pairs for a SuperSpeed USB receiver. When the receiver is detected, the RX termination becomes enabled and the NB7NPQ7021M is set to perform the redriver function.
The NB7NPQ7021M comes in a small 3 mm x 3 mm UQFN-16 package and is specified to operate across the entire industrial temperature range, -40-C to 85-C.
