PLL +1.8V Power Supply: This pin must be
connected to VDD18CORE for proper operation.
Refer to the LAN9313/LAN9313i application note
for additional connection information.
Crystal Input: External 25MHz crystal input. This
signal can also be driven by a single-ended clock
oscillator. When this method is used, XO should be
left unconnected.
Crystal Output: External 25MHz crystal output.
+3.3V Power Supply for I/O Pins and Internal
Regulator
Refer to the LAN9313/LAN9313i application note
for additional connection information.
Digital Core +1.8V Power Supply Output: +1.8V
power from the internal core voltage regulator. All
VDD18CORE pins must be tied together for proper
operation.
Refer to the LAN9313/LAN9313i application note
for additional connection information.
Common Ground
No Connect: These pins must be left floating for
normal device operation.
