DESCRIPTION
Demonstration kit 3160A-KIT is an Ethernet Alliance Gen
2 PoE certified, 24-port IEEE 802.3at/bt-compliant power
sourcing equipment (PSE) composed of a DC3159A
daughter card (48-channels) and DC3017A mother-
board (24, 4-pair ports). The DC3160A-KIT features the
LTC
9101-1/LTC9102/LTC9103
®
In the DC3160A-KIT, a single LTC9101-1 digital control-
ler interfaces with up to four analog controllers. The
DC3159A-A daughter card has four LTC9102, 12-chan-
nel, analog controllers for 48 power channels total. The
DC3159A-B daughter card has two LTC9102, 12-channel,
analog controllers and two LTC9103, 8-channel, analog
controllers for 40 power channels total. Up to twenty-
four IEEE 802.3af, IEEE 802.3at, or IEEE 802.3bt powered
devices (PDs) can be connected to the DC3160A-KIT and
powered from this system using a single power supply.

The LTC9101-1, LTC9102, and LTC9103 use a proprietary
isolated data interface allowing the LTC9101-1 to directly
connect to the host controller I
the need for costly opto-couplers and an additional 3.3V
supply. The DC3160A-KIT can operate completely autono-
mously without a host controller or with a DC590 for I
interfacing.
Robust surge protection is provided by design and
onboard surge protection devices. Indicator LEDs show
channel status for up to 48 power channels. An optional
on-board buck regulator provides 3.3V from the VEE
supply for the digital circuity. This demonstration man-
ual provides an auto mode quick start procedure and
