NB7VPQ701MMEVK NB7VPQ701MMEVK Evaluation Board User s Manual www.onsemi.com Introduction The NB7VPQ701MMEVK evaluation board was EVAL BOARD USERS MANUAL developed to provide a convenient platform to quickly verify the operation of the NB7VPQ701M redriver in a USB typeC system environment. This evaluation board manual contains: Information on the NB7VPQ701MMEVK Evaluation Kit Board Schematics Bill of Materials Part Description The NB7VPQ701M is a 1.8 V single channel redriver for USB 3.1 applications that supports both 5 and 10 Gbps data rates. Signal integrity degrades from PCB traces, transmission cables, and intersymbol interference (ISI). The NB7VPQ701M compensates for these losses by engaging varying levels of equalization at the input receiver. The output transmitter circuitry provides user selectable deemphasis and output amplitude 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. Control Board The NB7VPQ701M features an intelligent LFPS circuit. Demo Board This circuit senses the low frequency signals and automatically disables driver deemphasis for full USB 3.1 compliances. USB TypeC Cable After power up, the NB7VPQ701M 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 NB7VPQ701M is set to perform the redrive function. The NB7VPQ701M comes in a small 1.6 x 1.6 mm Figure 1.
