DEMO-ADIN1100D2Z

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

特性和优点

  • 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

产品详情

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.
