DP168x : Advanced Universal Serial Bus Full Speed Transceiver

General Description

The DP1680/1681/1682 Universal Serial Bus(USB) transceivers are fully compliant with the Universal Serial Bus Specification Rev. 2.0(full-speed section). It is ideal for use in portable electronic devices, such as mobile phones, digital still cameras, Personal Digital Assistants(PDAs) and Information Appliances(IAs). It allows USB Application Specific Integrated Circuits(ASICs) and Programmable Logic Devices(PLDs) with power supply voltages from 1.60 to 3.6V to interface with the physical layer of the USB.

It has an integrated 5V to 3.3V voltage regulator for direct powering via the USB supply line VBUS.
DP1682 has an integrated voltage detector to detect the presence of the VBUS line voltage(VCC, 5.0V).
When VBUS(VCC, 5.0V) is lost, the Pins(D+,D-) can be shared with other serial protocols.
The DP1680/1681/1682 can transmit and receive USB data at full-speed(12 Mbit/s). It allows single and differential input modes selectable by a MODE input.
The DP1680/1681/1682 are available in 3mm x 3mm 16- pin thin QFN package.
