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