描述 Description

The TUSB1105 and TUSB1106 universal serial bus (USB) transceivers are compliant with the Universal Serial Bus Specification Rev. 2.0. These devices can transmit and receive serial data at both full-speed (12-Mbit/s) and low-speed (1.5-Mbit/s) data rates. The TUSB1105 and TUSB1106 can be used as USB device transceivers or USB host transceivers.

The devices 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 (PHY) 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.

The TUSB1105 allows single-ended and differential input modes selectable by a mode (MODE) input and is available in RGT and RTZ packages. The TUSB1106 allows only differential input mode and is available in PW, RGT, RSV, and RTZ packages.

The TUSB1105 and TUSB1106 are ideal for portable electronic devices, such as mobile phones, personal digital assistants, information appliances, and digital still cameras.
