NB7NPQ7042M 3.3 V USB 3.1 Quad Channel/ Dual Port Linear Redriver Description The NB7NPQ7042M 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 www.onsemi.com that supports both 5 Gbps and 10 Gbps data rates. Signal integrity degrades from PCB traces, transmission cables, and intersymbol interference (ISI). The NB7NPQ7042M compensates for these losses MARKING by engaging varying levels of equalization at the input receiver, and flat DIAGRAM gain amplification on the output transmitter. The Flat Gain and Equalization are controlled by four level control pins. Each channel has NB7N a set of independent control pins to make signal optimization possible. 1 7042 After power up, the NB7NPQ7042M periodically checks both of the ALYW X2QFN34 TX output pairs of each port for a receiver connection. When the receiver CASE 722AL is detected on both channels, the RX termination becomes enabled of that respective port and is set to perform the redriver function. NB7N7042 = Specific Device Code The port becomes active once both TX outputs have detected A = Assembly Location L = Wafer Lot 50ohm termination, and the NB7NPQ7042M is set to perform the Y = Year redriver function. Port AB (channels A & B) and port CD (channels C W = Work Week & D) are independent of each other. = PbFree Package The NB7NPQ7042M comes in a small 3.1 x 4.3 mm X2QFN34 (Note: Microdot may be in either location) package and is specified to operate across the entire industrial temperature range, 40C to 85C.
