AN86947 - Optimizing USB 3.0 Throughput with EZ-USB® FX3™

Last Updated:

Cypress’s EZ-USB FX3, the next-generation USB 3.0 peripheral controller, provides highly integrated and flexible features that enable developers to add USB 3.0 functionality to any system.

USB 3.0 has a signaling rate of 5 Gbits per second, or 10 times the rate supported by USB 2.0. An FX3 device can deliver throughput close to the theoretical maximum supported by the USB 3.0 specification.

USB 3.0 promises a significant performance improvement over previous generations because it uses a 5-Gigabit-per-second (“SuperSpeed”) signaling rate. However, the maximum achievable throughput also depends on such critical factors as host PC controller type, operating system, and USB design (transfer type and buffer sizes). This application note shows you different strategies for using an EZ-USB®FX3™ controller to maximize USB 3.0 data transfers.
