ON Semiconductor – Re-drivers ensure signal integrity in USB Type-C systems

ON Semiconductor has introduced re-drivers which enable designers to maintain signal integrity at the high data rates supported by the latest USB standards.

Its single- and dual-channel USB re-drivers, the NB7VPQ701M and NB7VPQ702M, which have a small board footprint, both support USB3.0 and USB3.1 Gen 1 systems operating at up to 5Gbits/s, and USB3.1 Gen 2 operating at up to 10Gbits/s.

USB Type-C is emerging as the default industry standard for rapid charging and high- speed data transmission, capable of supplying 100W of power and transferring a 50Gbyte data file in just 38s. The default USB3.1 protocol for USB Type-C systems is capable of achieving ‘SuperSpeed+’ data rates of up to 10Gbits/s, theoretically twice as fast as the ‘SuperSpeed’ USB3.0.

While such high data rates are good for users who handle large data files or streaming data at high rates, they also create signal-integrity problems for the system designer.

Signal integrity can be impaired by PCB traces, connectors, flexible PCBs, cables and other system components, causing Inter-Symbol Interference (ISI) which degrades the deterministic component of the total jitter budget.

The NB7VPQ701M and NB7VPQ702M devices can compensate for these losses by providing varying levels of user-selectable equalisation at the input receiver and de- emphasis on the output transmitter. These techniques may be combined to optimise the eye opening for the outgoing data signals, enabling the system to comply with the tight defined specifications of the USB standard.

The NB7VPQ701M and NB7VPQ702M are proven to restore signal integrity and to extend signal range up to 36 inches of FR4 PCB trace, or 5m of cable at a data rate of 5Gbits/s.
