Ethernet
The STR910-EVAL supports IEEE-802.3-2002 compliant Ethernet communication via the
MII interface PHY transceiver– STE100P with PHY address 10101b and integrated RJ45
connector with embedded transformer. JP24 enables/disables Ethernet support.

Sets the clock source for Ethernet PHY to X3 or STR91xF.
To use the 25MHz clock from the STR91xF P52, set JP25 as
shown on the right:
(Default setting)
To use the 25MHz clock from X3, set JP25 as shown on the
right:
Enables the external USB 48MHz clock source.
To use an external oscillator via P27 of the STR91xF for the USB clock input, JP17 is
fitted.
To use the internal clock of the STR91xF, JP17 is not fitted. In this case P27 can be
used for an alternate function.
Default setting: Not fitted
PHY transceiver STE100P is in Power Down mode when JP24 is not fitted.
Default setting: Fitted
