Placement:

•

At USB side, place ADM8513/X and USB connector as close as possible.

•

At Ethernet side, place ADM8513/X, transformer and RJ45 as close as possible.

•

The crystal or OSC device should be closed to ADM8513/X and away from the following items

– Any analog signal

– PCB edge

– Any other high frequency components and their associated traces.

If you can't avoid those designs, please add a Resistor between Crystal (or OSC) and ADM8513/X chip clk48_I

pin as figure show:

Placement 1

•

Place the filtering capacitor as closed as possible at the Vcc pin of ADM8513/X and its trace must be short and

wide.
