The NB7NPQ701M is a 3.3 V single Channel redriver 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 NB7NPQ701M compensates for these losses by engaging varying levels of equalization at the input receiver and de-emphasis on output driver. The output transmitter circuitry provides user selectable de-emphasis and output amplitude settings to create the best eye openings for the outgoing data signals.
The NB7NPQ701M features an intelligent LFPS Controller. This controller senses the low frequency signals and automatically disables driver de-emphasis for full USB 3.1 Gen 1 and USB 3.1 Gen 2 compliances.
After power up, the NB7NPQ701M periodically checks both of the TX output pairs for a receiver connection. When the receiver is detected the RX termination becomes enabled and the NB7NPQ701M is set to perform the re-drive function.
