USB Transceiver 1TR WLCSP T/R

SMSC’s USB3330 is a family of High 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. Each model in the USB3330 family may use a 60MHz reference clock USB3330 can support several different frequencies driven on the REFCLK pin. The configuration of the frequency selection pins set the desired reference frequency. Several advanced features make the USB3330 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 USB3330 from voltages up to 30V on the VBUS pin. By using a reference clock from the Link, the USB3330 removes the cost of a dedicated crystal reference from the design. The USB3330 includes integrated 3.3V and 1.8V regulators, making it possible to operate the device from a single power supply. The USB3330 is optimized for use in portable applications where a low operating current and standby current is essential. The USB3330 also supports the Link Power Management protocol (LPM) to further reduce USB operating currents. The USB3330 also includes integrated battery charger detection circuitry. These circuits are used to detect the attachment of a USB Charger By sensing the attachment to a USB Charger, a product using the USB3330 can draw more than 500mA from the USB connector. The USB3330 meets all of the electrical requirements for a High Speed USB Host, Device, or an Onthe-Go (OTG) transceiver. In addition to the supporting USB signaling, the USB3330 also provides USB UART mode and, in versions with the integrated USB switch, USB Audio mode. USB3330 uses the industry standard UTMI+ Low Pin Interface (ULPI) to connect the USB PHY to the Link. ULPI uses a method of in-band signaling and status byte transfers between the Link and PHY to facilitate a USB session with only twelve pins. The USB3330 uses SMSC’s “wrapper-less” technology to implement the ULPI interface. This “wrapperless” technology allows the PHY to achieve a low latency transmit and receive time. SMSC’s low latency transceiver allows an existing UTMI Link to be reused by adding a UTMI to ULPI bridge. By adding a bridge to the ASIC the existing and proven UTMI Link IP can be reused. Versions of the USB3330 with the integrated USB switch enable a single USB port of connection.
