DESCRIPTION
The Universal Serial Bus Hub PDIUSBH11A is a cost and feature optimized second generation USB Hub with 4 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 I2C 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 PDIUSBH11A is ideally suited for computer monitors, docking stations, keyboards and many other applications that use the I2C or the SMBUS based architecture. The PDIUSBH11A conforms to the USB specification Rev 1.0, I2C serial interface and the SMBUS specifications. It is fully compliant with the Human Interface Device Class and Monitor Control Class specifications. Its...
