MICROCHIP  USB3340-EZK  芯片, 收发器, 多频率USB2.0 ULPI PHY, 32VQFN

The is an Enhanced Single Supply Hi-Speed USB ULPI Transceiver provides 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. 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. It includes integrated 3.3 and 1.8V regulators, making it possible to operate the device from a single power supply.
