MICROCHIP USB3343-CP

USB334x is a family of Hi-Speed USB 2.0 Transceivers that provide a physical layer (PHY) solution well - suited for portable electronic devices. Both commercial and industrial temperature applications are supported. Each model in the USB334x family may use a 60MHz reference clock or the model - number specific reference clock shown on the Product Identification System page. Several advanced features make the USB334x the transceiver of choice by reducing both 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 USB334x from voltages up to 30V on the VBUS pin. By using a reference clock from the Link, the USB334x removes the cost of a dedicated crystal reference from the design. The USB334x includes integrated 3.3V and 1.8V regulators, making it possible to operate the device from a single power supply.
