logic functions into a single 64-pin, plastic pack. It is
used in Ethernet switches and Midspans to allow next
generation network devices to share power and data
over the same cable.
The device is a twelve-port, mix-signal, high-voltage
Power over Ethernet driver. The PoE Manager allows
the detection of IEEE 802.3af-2003 compliant
terminals, referred to as powered devices or PDs,
ensuring safe power feeding and removal over
Ethernet ports. With full digital control via a serial
communication interface and a minimum of external
components, the device integrates in multi-port and
highly populated Ethernet switches.
The PD64012 implements all real time functions
according to IEEE 802.3af-2003, including: detection,
classification, and port status monitoring; as well as
system level activities such as: power management
and MIB support, for system management. The PoE
Manager is designed to detect and disable
disconnected ports, using both DC and AC
disconnect methods, as defined in IEEE 802.3af-
2003.
The
PD64012
has
two
possible
working
configurations: an Auto mode (stand-alone topology)
for basic PoE functions and an Enhanced mode for
extended functions.
