ISP1107

ISP1107 Advanced Universal Serial Bus transceiver Rev. 01 — 23 February 2000 Objective specification 1. General description The ISP1107 is a Universal Serial Bus (USB) transceiver that is fully compliant with the Universal Serial Bus Specification Rev. 1.1. It is ideal for portable electronics devices such as mobile phones, digital still cameras and personal digital assistants. It allows 1.8 V, 2.5 V and 3.3 V USB Application Specific ICs (ASICs) and Programmable Logic Devices (PLDs) to interface with the physical layer of the Universal Serial Bus. It has an integrated 5 V to 3.3 V voltage regulator allowing direct powering from the USB supply VBUS. The ISP1107 can be used as a USB device transceiver or a USB host transceiver. It can transmit and receive serial data at both full-speed (12 Mbit/s) and low-speed (1.5 Mbit/s) data rates. The ISP1107 is compatible with the industry-standard Philips Semiconductors USB transceiver PDIUSBP11A. 2.
