ISP1102W

ISP1102 Advanced Universal Serial Bus transceiver Rev. 03 — 02 September 2003 Product data 1. General description The ISP1102 Universal Serial Bus (USB) transceiver is fully compliant with the Universal Serial Bus Specification Rev. 2.0. The ISP1102 can transmit and receive USB data at full-speed (12 Mbit/s). The transceiver allows USB Application Specific ICs (ASICs) and Programmable Logic Devices (PLDs) with power supply voltages from 1.65 to 3.6 V to interface with the physical layer of the USB. The transceiver has an integrated 5 V-to-3.3 V voltage regulator for direct powering via the USB supply line VBUS. The transceiver has an integrated voltage detector to detect the presence of the VBUS voltage (VCC(5.0)). When VCC(5.0) or Vreg(3.3) is lost, the D+ and D− pins can be shared with other serial protocols. The transceiver is a bi-directional differential interface and is available in HBCC16 and HVQFN14 packages. The transceiver is ideal for use in portable electronic devices, such as mobile phones, digital still cameras, personal digital assistants and information appliances. 2.
