Overview
The NB7NPQ1102M is a high-performance single-port linear redriver designed by onsemi for USB 3.1 Gen 1 and USB 3.1 Gen 2 applications. It supports both 5 Gbps and 10 Gbps data rates, addressing signal integrity degradation caused by PCB traces, transmission cables, and inter-symbol interference (ISI). The device compensates for these losses through programmable equalization at the input receiver and flat gain amplification on the output transmitter. It features automatic receiver detection, integrated input and output termination, and adaptive power management to minimize power consumption.
