Note: Stresses above those listed could cause damage to the device. This is a stress rating only and functional operation of the device at any other condition above those indicated in the operation sections of this specification is not implied. When powering this device from laboratory or system power supplies, it is important that the Absolute Maximum Ratings not be exceeded or device failure can result. Some power supplies exhibit voltage spikes on their outputs when the AC power is switched on or off. In addition, voltage transients on the AC power line may appear on the DC output. If this possibility exists, it is suggested that a clamp circuit be used.




Description

The USB3450 is a stand-alone Hi-Speed USB Physical Layer Transceiver (PHY). The USB3450 uses a UTMI+ interface to connect to an SOC or ASIC or FPGA. SMSC's advanced proprietary technology minimizes power dissipation, resulting in maximum battery life for portable applications. The USB3450 is a flexible solution for adding USB to new designs without integrating the analog PHY block.
