27.3 LED Output Pins (LED[4:0])
The following specifications are valid over a voltage range of 2.3v to 1.3v applied to the LED[4:0] pins.
28 Clocking Specifications
28.1 Reference Clock Option
The following component specifications should be used to select a clock reference for use with the VSC8211. For more
information about clocking and frequency offset tolerance specifications when jumbo packet support is required, see the
application note Using Jumbo Packets with SimpliPHYs.

VMDS-10105 Revision 4.1
October 2006
It is assumed that a typical LED will have a forward voltage drop between 1v and 2v, thereby asserting a 1.3v (3.3v-2v) to 2.3v (3.3v-1v) signal
across the LED.
This recommendation is purely from a power savings view point.
