SP5301 Universal Serial Bus Transceiver Utilizes digital inputs and outputs to transmit and receive USB cable data Supports 2MbpsFull Spee and .5MbpsLow Spee serial data transmission Compatible with the VHDLSerial Interface Engin from USB developer s conference Hysteresis on VP and VM Function) Ease of use for PC peripheral expansion Protocol flexibility for mixed-mode isochronous data transfers and asynchronous messaging Available in 4 pin TSSOP package Rail to Rail receiver common mode input range, 20mV typical receiver sensitivity Low Power 20 nA in SUSPEND mode Enhanced version of the PDIUSBP DESCRIPTION The SP530 is a half-duplex Universal Serial Bus (USB) differential transceiver that interfaces with the USB Serial Interface Engine (SIE). The SP530 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 27 physical devices composed of many diverse functions. It is capable of transmitting and receiving serial data at both full speed ( 2Mbps) and low speed (.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.
