10.7 Serial MAC to Fiber/CAT5 Media PHY Operating Mode
1
VMDS-10105 Revision 4.1
October 2006
The Transition from 'Serial MAC to CAT5' PHY Operating mode to 'Serial MAC to Fiber' PHY Operating mode and vice versa is managed by
VDDIOMICRO
the 'Station Manager' by writing to PHY Register 23.15:12,2:1, based on the SIGDET input from the Fiber Optic connector.
Note that power supply sequencing is not needed to bring the device out of reset. Once the supplies are stable, the device reset can be de-
asserted.
