EVAL-SPoE-KIT-AZ

SPoE Evaluation Kit

Product Details

The EVAL-SPoE-KIT-AZ is an IEEE 802.3cg single-pair, power over Ethernet (SPoE) evaluation kit. The kit features the LTC4296-1, 5-Port SPoE power sourcing equipment (PSE) controller, and the LTC9111, SPoE powered device (PD) for evaluation of IEEE 802.3cg Class 10 through 15 SPoE power. The ADIN1100, 10BASE-T1L PHY provides the Ethernet data in the system.

DEMO-ADIN1100D2Z

10BASE-T to 10BASE-T1L Media Converter Including SPoE/APL, Featuring ADIN1100 and ADIN1200 Ethernet PHYs and LTC4296-1 PSE Controller

Features and Benefits

  • 10BASE-T to 10BASE-T1L media converter
  • SPoE PSE controller compatible with IEEE 802.3cg
  • Power source for APL devices
  • System level diagnostics over USB COM port

Product Details

The DEMO-ADIN1100D2Z is a media converter board that provides connection between a standard 10BASE-T RJ45 Ethernet port and a 10BASE-T1L device.

The DEMO-ADIN1100D2Z includes a power sourcing equipment (PSE) controller and it can power the connected 10BASE-T1L or advanced physical layer (APL) device. The PSE controller is configurable for power over data line (PoDL)/single pair power over Ethernet (SPoE) power Class 10, Class 11, Class 12, Class 13, Class 14, and Class 15, and APL power Class A, Class C, and Class 3.

The board requires an external DC power supply with output voltage and maximum output current relevant to the selected power class. For a subset of power classes (Class 10, APL A, and APL C), the board can also be powered from a USB host.

The board requires a minor modification and external power coupling inductors when used for the highest power Class 15 and APL 3.

The DEMO-ADIN1100D2Z can be used as an autonomous device, configurable by a set of switches and jumpers, indicating its status on LEDs.

The DEMO-ADIN1100D2Z can also be connected via USB to a host PC. The 10BASE-T1L link status, power status, and diagnostics are then accessible using a simple set of text commands and messages exchanged over the USB COM port interface using a serial terminal software on a PC.

EVAL-10BT1L-MCS

EVAL-10BT1L-MCS IEEE 802.3cg SPoE Shield

Features and Benefits

  • Injects or receives power from the IEEE 802.3cg-compliant SPoE cable
  • 10BASE-TX to 10BASE-T1L data conversion

Product Details

The EVAL-10BT1L-MCS is a 10BASE-TX, traditional 4-pair Ethernet, to 10BASE-T1L single-pair power over Ethernet (SPoE) media converter shield (MCS) that is compatible with SPoE power sourcing equipment (PSE) and powered device (PD) evaluation motherboards.

The EVAL-10BT1L-MCS-AZ shield power coupling network is suited for Class 10 through Class 14 power levels. The EVAL-10BT1LMCS- BZ shield power coupling network is suited for the higher power levels of Class 15 while compatible with Class 10 through Class 14. In the context of a PSE, the power coupling network allows for power to be coupled on the single pair Ethernet lines. Regarding the PD, the power coupling network extracts power from the combined power and data line.

The shield includes the ADIN1100, 10BASE-T1L PHY, and the ADIN1200, 10BASE-TX PHY, which provide the Ethernet data media conversion in the system. The on-board LT8301, isolated flyback converter, provides an isolated 3.3V power source to the PHYs.
