PDIUSBH11A

PIN DESCRIPTION

The PDIUSBH11A has two modes of operation. The first mode (Mode 0) configures the pins DNx_GL_N for GoodLink™ LED indication. The

second mode (Mode 1) configures the LED pins as per port overcurrent condition pins. An overcurrent condition on any port can be uniquely

identified in Mode 1. However, all downstream ports are disabled as a result of a single overcurrent condition. In addition to the two modes of

operation, the PDIUSBH11A can also be configured to take either a 48 MHz crystal oscillator (for backward compatibility to PDIUSBH11) or a 12

MHz crystal.

The internal 4X clock multiplier PLL will be activated when 12 MHz input XTAL mode is selected. Also, the output clock frequency is now

programmable rather than fixed to 12 MHz. The output clock frequency can be programmed through the Set Mode command. All these new

features are added while maintaining backward compatibility to the PDIUSBH11 through TEST2 and TEST1 pins.
