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 motherboard

(24, 4-pair ports). The DC3160A-KIT features the

LTC?9101-1/LTC9102/LTC9103 PSE platform chipset.

In the DC3160A-KIT, a single LTC9101-1 digital controller

interfaces with up to four analog controllers. The

DC3159A-A daughter card has four LTC9102, 12-channel,

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 twentyfour

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 I2C interface and eliminates

the need for costly opto-couplers and an additional 3.3V

supply. The DC3160A-KIT can operate completely autonomously

without a host controller or with a DC590 for I2C

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 manual

provides an auto mode quick start procedure and
