DESCRIPTION

The Universal Serial Bus hub PDIUSBD11 is a cost and

feature-optimized USB interface device. It is used in

microcontroller-based systems and communicates with the system

microcontroller over the high speed I2C serial bus. This modular

approach to implementing USB functions allows the designer to

choose the optimum system microcontroller from the available wide

variety. This flexibility cuts down the development time, risks, and

costs by allowing the use of the existing architecture and the

firmware investments. This results in the fastest way to develop the

most cost-effective USB peripheral solutions. The PDIUSBD11 is

ideally suited for computer monitors, docking stations, keyboards,

and many other applications that use the I2C or the SMBus-based

architecture.

The PDIUSBD11 conforms to the USB specification Rev. 1.1, I2C

serial interface and the SMBus specifications. It is fully compliant

with the Human Interface Device Class and Monitor Control Class

specifications. Its low suspend power consumption along with the

programmable LazyClock output allows for easy implementation of

equipment that is compliant to the ACPI, OnNOW, and USB power

management requirements. The low operating power allows the

implementation of bus-powered function.

The PDIUSBD11 is fully backward compatible to the

PDIUSBH11/PDIUSBH11A software. In addition, it also incorporates

the feature enhancements like SoftConnect™, LazyClock,

programmable clock output, lower frequency crystal oscillator,

multiple function endpoints and integration of termination resistors.

All of these feature enhancements contribute to significant cost

savings in the system implementation and at the same time ease the

implementation of advanced USB functionality into the peripherals.
