Product Description:

The USB Hub PDIUSBH12 is a 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 I2C serial bus.
The PDIUSBH12 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 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.

28-Pin Plastic SO
* High speed slave I2C Interface (up to 1 Mbit/s)
* Good USB downstream connection indicators that blink with traffic (GoodLink)
* Low frequency 12 MHz crystal oscillator eases EMI design issues
* Programmable output clock frequency
* Bus powered capability with very low suspend current
* Controllable LazyClock output at 30 kHz (nominal) during suspend
* Single 3.3V supply with 5V tolerant I/O
* Full-scan design with high fault coverage (>99%) insures high quality
* Higher than 8 KV in-circuit ESD protection lowers cost of extra components
