• Supports serial communication classification protocol (SCCP)

The EVAL-LTC9111-AZ is an evaluation motherboard featuring the LTC9111, an IEEE 802.3cg-compliant single pair power over Ethernet (SPoE) powered device (PD) controller.

With the LTC9111 wide operating range of 2.3V to 60V, the EVALLTC9111- AZ may be configured with class jumpers to IEEE 802.3cg 24V power classes (Class 10 to Class 12) or 52V power classes (Class 13 to Class 15).

The EVAL-LTC9111-AZ motherboard headers (J1, J2, and J3) connect to SPoE shields, the EVAL-10BT1L-MCS-AZ (Class 10 to Class 14) or the EVAL-10BT1L-MCS-BZ (Class 15). The EVALLTC9111- AZ motherboard with a shield connects via a single pair Ethernet (SPE) cable to an IEEE 802.3cg SPoE power sourcing equipment (PSE) for power.

The EVAL-LTC9111-AZ incorporates both IEEE 802.3cg-compliant wakeup signature and SCCP-based classification.

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

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.

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.

The AD-SWIOT1L-SL provides a complete software and hardware platform for prototyping intelligent, secure, network capable field devices.

The design incorporates the AD74413R Quad-Channel, Software Configurable Input and Output and the MAX14906 Quad-Channel Industrial Digital Output/Digital Input ICs, allowing the multiplexing of several analog and digital functions on four channels which can be independently configurable through software to act as:

• voltage output / input
• current output / input
• digital input / output
• RTD measurement

A 10 Mbps single-pair Ethernet link, using the ADIN1110 10BASE-T1L MAC/PHY, enables remote data acquisition and device configuration. The 10BASE-T1L interface can also be used for powering the system via the Single-pair Power over Ethernet (SPoE) technology using the LTC9111 Powered Device (PD) controller. This way, power and data for the system is provided over the same cable to significantly simplify the cabling infrastructure and cost.

For applications requiring high current capabilities, the system can be powered from an external 24 V supply and up to 1.2 A can be output on any of the channels configured as digital outputs. The power supply solution also includes the ADP1032 high performance, isolated micropower management unit (PMU) to provide power and digital control for software configurable I/O devices in one of the most compact formats. The LT8304 Micropower No-Opto Isolated Flyback Converter completes the power tree to provide isolated power to the digital part of the design.

The on-board MAX32650 Ultralow Power ARM^® Cortex^®-M4 Microcontroller exposes all the necessary debug and programming features to enable a complete software development experience with the system. It is coupled with a 1 Gb (128 MB) external RAM and a 64 Mb (8 MB) external flash memory to meet the most demanding applications and provide the flexibility to implement any protocol stack. Security features are enabled by the MAXQ1065 security coprocessor.

The system is accompanied by an open-source software stack and associated collateral, enabling a complete experience from evaluation and prototyping all the way to production firmware and applications development. An external programmer such as the MAX32625PICO MAXDAP Programming Adapter, or any other similar programmer supporting the SWD interface, is required to enable firmware programming and debug. The system’s firmware is based on Analog Devices’ open-source no-OS framework which includes all the tools required for embedded code development and debugging as well as libraries enabling host-side connectivity for system configuration and data transfer over the UART or the 10BASE-T1L interfaces. A PC application with a user-friendly graphical interface is provided to enable easy system configuration and displaying the acquired data in different ways.
