[1] The ISP1506 has been tested according to the additional requirements listed in Ref. 1 "Universal Serial Bus Specification Rev. 2.0",
Section 7.1.1. The short circuit withstand test and the AC stress test were performed for 24 hours, and the ISP1506 was found to be fully operational after the test completed.
[2] Equivalent to discharging a 100 pF capacitor through a 1.5 kW resistor (Human Body Model JESD22-A114D).
DescriptionThe ISP1506 is a Universal Serial Bus (USB) On-The-Go (OTG) transceiver that is fully compliant with Ref. 1 "Universal Serial Bus Specification Rev. 2.0", Ref. 2 "On-The-Go Supplement to the USB 2.0 Specification Rev. 1.2" and Ref. 3 "UTMI+ Low Pin Interface (ULPI) Specification Rev. 1.1".
The ISP1506 can transmit and receive USB data at high-speed (480 Mbit/s), full-speed (12 Mbit/s) and low-speed (1.5 Mbit/s), and provides a pin-optimized, physical layer front-end attachment to USB host, peripheral and OTG devices.
It is ideal for use in portable electronic devices, such as mobile phones, digital still cameras, digital video cameras, Personal Digital Assistants (PDAs) and digital audio players. It allows USB Application-Specific Integrated Circuits (ASICs), Programmable Logic Devices (PLDs) and any system chip set to interface with the physical layer of the USB through an 8-pin interface.
The ISP1506 can interface to devices with digital I/O voltages in the range of 1.65 V to 1.95 V.
The ISP1506 is available in HVQFN24 package.
