PD69008 - 8 Ports Power Over Ethernet Manager
Description _________________
Microsemi’s PD69008 Power over Ethernet (PoE)
Manager chip integrates power, analog and state of
the art embedded core logic into a single 80-pin,
plastic QFP package. The device is used in Ethernet
switches and Midspans to enable network devices to
share power and data over the same cable.
PD69008 device is an 8-port, mixed-signal, high-
voltage Power over Ethernet driver. It enables
detection of IEEE802.3af-2003 compliant PDs
(Powered Devices) and IEEE802.3AT High Power
Devices, thus, ensuring safe power feeding and
disconnection of ports. With full digital control via a
serial communication interface and a minimum of
external components, the device integrates into multi-
port and highly populated Ethernet switches and
routers.
The PD69008 executes all real time functions as
specified in the IEEE802.3af-2003 (“AF”) standard
and IEEE802.3at High Power (“AT”) functionality,
including load detection, “AF” and “AT” classification
and port status monitoring. In addition it performs
system level activities such as power management
and MIB support for system management. The PoE
device is designed to detect and disable
disconnected ports, utilizing both DC and AC
disconnection methods, as specified in the
IEEE 802.3af-2003 standard.
The PD69008 is designed to support 2 main
configurations:
• Auto mode: For Basic ”AF” and “AT” PSE
equipment
• Enhanced mode: For High End, Extended
features set of AF and AT PSE equipment
