For auxiliary devices, a Universal Serial Bus (USB) transceiver is offered. The PHY is compliant with USB 3.0, USB 2.0 PIPE, and UTMI specifications (USB SuperSpeed). The USB3.0 PHY IP transceiver is designed to consume little power and take up little space on the chip without compromising speed or data throughput. By providing a full on-chip physical transceiver solution with Electrostatic Discharge (ESD) protection, an integrated self-test module with built-in jitter injection, and a dynamic equalization circuit, the USB3.0 PHY IP delivers total support for high-performance designs. The USB3 MAC layer enables numerous IP sources using the same PHY interface (PIPE). Internal test monitoring and jitter are eliminated using constant power, built-in Jitter Injection Output, built-in Self-Test, and authorized customization of analog circuit characteristics.
