SP5301

Universal Serial Bus Transceiver

The SP5301 is a half-duplex Universal Serial Bus (USB) differential transceiver that interfaces

with the USB Serial Interface Engine (SIE). The SP5301 is designed to allow 3.3V or 5.0V

standard and programmable logic to interface with the physical layer of the Universal Bus. The

USB protocol can support multiple connections for up to 127 physical devices composed of

many diverse functions. It is capable of transmitting and receiving serial data at both full speed

(12Mbps) and low speed (1.5Mbps) data rates. Implementation of the Serial Interface Engine

along with the USB transceiver allow the designer to make flexible USB compatible devices

with widely available logic components. The SP5301 is specifically geared towards low-cost

USB solutions for the PC peripheral market.
