Overview

The USB3300-EZK is a high-speed USB 2.0 physical layer (PHY) transceiver featuring a ULPI interface. It is designed to handle the complex signaling of Hi-Speed USB while offloading the physical layer implementation from the host controller or FPGA.

Why Choose This Part

The device features a highly integrated design with an internal 1.8V regulator and a 24MHz crystal oscillator, reducing the external bill of materials. It also provides robust ESD protection up to plus or minus 8kV HBM and is compliant with ULPI revision 1.1 for broad compatibility with standard link layers.

Applications

Embedded Host Controllers
Interfacing FPGAs or microcontrollers without integrated PHYs to high-speed USB peripherals.
USB OTG Devices
Portable electronics requiring the ability to switch between host and peripheral roles using HNP and SRP protocols.
Industrial Computing
Adding robust USB 2.0 connectivity to industrial PC motherboards or embedded industrial modules.

Getting Started

To integrate the USB3300, connect the 12-pin ULPI interface to a compatible link layer controller such as an FPGA or high-end MCU. Ensure the 24MHz crystal or clock source is stable to allow the internal PLL to generate the 480MHz required for Hi-Speed operation.
