ISP1105/1106
Advanced USB transceivers
Rev. 10 — 28 September 2009
Product data sheet
1. General description
The ISP1105/1106 range of Universal Serial Bus (USB) transceivers are compliant with
the Universal Serial Bus Specification Rev. 2.0. They can transmit and receive serial data
at both full-speed (12 Mbit/s) and low-speed (1.5 Mbit/s) data rates. The ISP1105/1106
range can be used as a USB device transceiver or a USB host transceiver.
They allow USB Application Specific ICs (ASICs) and Programmable Logic Devices
(PLDs) with power supply voltages from 1.65 V to 3.6 V to interface with the physical layer
of the Universal Serial Bus. They have an integrated 5 V-to-3.3 V voltage regulator for
direct powering via the USB supply VBUS.
ISP1105 allows single-ended and differential input modes selectable by a MODE input
and it is available in HVQFN16 and HBCC16 packages. ISP1106 allows only differential
input mode and is available in both TSSOP16 and HBCC16 packages.
The ISP1105/1106 are ideal for portable electronics devices such as mobile phones,
digital still cameras, Personal Digital Assistants (PDA) and Information Appliances (IA).
