MICROCHIP USB3321C-GL-TR

USB332x is a family of Hi-Speed USB 2.0 Transceivers that provides a physical layer (PHY) solution well - suited for portable electronic devices. Both commercial and industrial temperature applications are supported. Several advanced features make the USB332x the transceiver of choice by reducing both electrical bill of material (eBOM) part count and printed circuit board (PCB) area. Outstanding ESD robustness eliminates the need for external ESD protection devices in typical applications. The internal Over - Voltage Protection circuit (OVP) protects the USB332x from voltages up to 30V. By using a reference clock from the Link, the USB332x removes the cost of a dedicated crystal reference from the design. And the integrated USB switch enables unique product features with a single USB port of connection. The USB332x meets all of the electrical requirements to be used as a Hi - Speed USB Host, Device, or an On - the - Go (OTG) transceiver. In addition to the supporting USB signaling, the USB332x also provides USB UART mode and USB Audio mode. USB332x uses the industry standard UTM + Low Pin Interface (ULPI) to connect the USB PHY.
