DESCRIPTION
The Universal Serial Bus Hub PDIUSBH12 is a cost and feature
optimized second generation USB Hub with 2 downstream ports and
3 embedded functions (compound hub). It is normally used in any
microcontroller-based system and communicates with the system
microcontroller over the high speed I
2
C serial bus. This modular
approach to implementing a hub and embedded 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 that need
hub functionality. The PDIUSBH12 is ideally suited for computer
monitors, docking stations, keyboards and many other applications
that use the I
2
C or the SMBus based architecture.
The PDIUSBH12 conforms to the USB specification Rev 1.0, I
2
C
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 the bus powered or the compound powered hub
function.
The PDIUSBH12 is fully backward compatible to the first generation
PDIUSBH11 hardware and software. This allows an easy running
change in the manufacturing line to realize the cost savings. In
addition, it also incorporates the feature enhancements like
SoftConnect
, GoodLink
, LazyClock, programmable clock output,
lower frequency crystal oscillator, additional embedded functions
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.
