ISP1105/1106/1107

Advanced Universal Serial Bus transceivers

Rev. 06 — 30 November 2001 Product data

1. General description

The ISP1105/1106/1107 range of Universal Serial Bus (USB) transceivers are fully
compliant with the
portable electronics devices such as mobile phones, digital still cameras, Personal
Digital Assistants (PDA) and Information Appliances (IA).

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 V

The ISP1105/1106/1107 range can be used as a USB device transceiver or a USB
host transceiver. They can transmit and receive serial data at both full-speed
(12 Mbit/s) and low-speed (1.5 Mbit/s) data rates.

ISP1105 allows single/differential input modes selectable by a MODE input and it is
available in HBCC16 package. ISP1106 allows only differential input mode and is
available in both TSSOP16 and HBCC16 packages. ISP1107 allows only
single-ended input mode and is available in both TSSOP16 and HBCC16 packages.

[1] Signal levels on (D+, D−) are determined by other USB devices and external pull-up/down resistors.
[2] In ‘suspend’ mode (SUSPND = HIGH) the differential receiver is inactive and output RCV is always

LOW. Out-of-suspend (‘K’) signalling is detected via the single-ended receivers VP and VM.

[3] During suspend, the slew-rate control circuit of low-speed operation is disabled. The (D+, D−) lines

are still driven to their intended states, without slew-rate control. This is permitted because driving
during suspend is used to signal remote wake-up by driving a ‘K’ signal (one transition from idle to
‘K’ state) for a period of 1 to 15 ms.
