Device Overview

Summary

The USB3450 is a stand-alone Hi-Speed USB Physical Layer Transceiver (PHY). The USB3450 uses a UTMI+ interface to connect to an SOC or ASIC or FPGA. Microchip's advanced proprietary technology minimizes power dissipation, resulting in maximum battery life for portable applications. The USB3450 is a flexible solution for adding USB to new designs without integrating the analog PHY block.

The USB3450 provides a fully compliant Hi-Speed interface, and supports Hi-Speed (HS), Full-Speed (FS), and Low-Speed (LS) USB. The USB3450 supports all levels of the UTMI+ specification.
