Analog Devices Inc. EVAL-LTC9101-2/2A/3 Evaluation Kits

Analog Devices EVAL-LTC9101-2/2A/3 Evaluation Kits include a daughter card and motherboard demonstrating the LTC9101-2A, LTC9101-2, or LTC9101-3 digital controller. The LTC9101-2A/LTC9101-2 uses a proprietary isolated data interface, enabling the LTC9101-2 to connect directly to the host controller I²C interface and eliminating the need for costly optocouplers and an additional 3.3V supply.

The EVAL-LTC9101-2 KIT includes the DC3159A-D or DC3159A-C daughter card, the DC3017A-B motherboard, and features the LTC9101-2A/LTC9101-2 and LTC9102 chipset. In the EVAL-LTC9101-2 KIT, the daughter card has a single LTC9101-2A or LTC9101-2 digital controller. The DC3159A-D daughter card has the LTC9101-2A, and the DC3159A-C has the LTC9101-2. The digital controller interfaces with four LTC9102 (12-channel) analog controllers for a total of 48x PSE channels.

The ADI EVAL-LTC9101-2A Kit connects to up to forty-eight 802.3af/at PDs with an Ethernet splitter for each of two ports for 2-pair power evaluation. This kit version needs host control over I²C. The EVAL-LTC9101-2 Kit connects to up to twenty-four 802.3af/at/bt PDs directly at each port for 4-pair power evaluation. This kit version can operate autonomously or with host control over I²C. The EVAL-LTC9101-3 is a 16-channel IEEE 802.3at compliant power sourcing equipment (PSE) with autonomous power management and serial LED driver for port LEDs. The EVAL-LTC9101-3 includes the EVAL-LTC9101-3-AZ daughter card and the EVAL-LTC9101-3-MBAZ motherboard and features the LTC9101-3 and LTC9103 PSE platform chipset.
