Product data
1. General description
The ISP1501 is a full-function transceiver designed to provide a Hi-Speed Universal
Serial Bus (USB) analog front-end to Application-Speci鏗乧 Integrated Circuits (ASICs)
and Field Programmable Gate Arrays (FPGAs) with a built-in USB Serial Interface
Engine (SIE). A Hi-Speed USB transceiver is integrated to implement USB
connectivity for high-speed peripherals. In addition, an Original USB transceiver
provides backward compatibility with full-speed USB systems. A minimum number of
external components is needed.
