Beschreibung
The EVAL-LTC9101-2 is a 48-channel IEEE 802.3at/bt compliant power sourcing equipment (PSE). The EVAL-LTC9101-2 includes the DC3159A-C, DC3159A-D, or DC3159A-E daughter card, the DC3017A-B motherboard, and features the LTC9101-2/ LTC9101-2A/LTC9101-2B and LTC9102 chipset.In the EVAL-LTC9101-2, the daughter card has a single LTC9101-2x digital controller, where X denotes either the LTC9101-2, LTC9101-2A, or the LTC9101-2B. The DC3159A-C has the LTC9101-2, the DC3159A-D daughter card has the LTC9101-2A and the DC3159A-E has the LTC9101-2B. The digital controller interfaces with four LTC9102 (12-channel) analog controllers for a total of 48 PSE channels.
