A.8. Communication Interfaces

SFP+

The Agilex™ 5 FPGA E-Series 065B Modular Development Kit supports 1x SFP ports. The SFP port fans out from the transceiver channel 1C and port UX3. SFP supports 10G data rate.

TSN/SGMII

The Agilex™ 5 FPGA E-Series 065B Modular Development Kit supports 2x 2.5G TSN over the SGMII interface from the transceiver bank 1C. Ports UX0 and UX1 realize this interface on the Carrier board.

FMC

The Agilex™ 5 FPGA E-Series 065B Modular Development Kit supports 1x FMC+ slot for functional expandability. The x8 FGT lanes from banks 1A and 1B are terminated to FMC J7.

Serial Buses

The Agilex™ 5 FPGA E-Series 065B Modular Development Kit supports 4 major I2C masters from the MAX® 10 BMC.

PMBus

All the voltage regulators with I2C/PMBus support can be accessed through this bus. The bus is shared among the VRs on the Carrier and Modular boards. Over the Modular board, there is a provision to isolate the PMBus from the SDM SVID bus. Refer to I2C tree for further details.

Telemetry

Temperature sensors, current sensors, and EEPROM on the Carrier board are communicated over this bus. This bus is shared with current monitoring, temperature monitoring, power sequences, and reset control components.

This telemetry bus is shared with HPS I2C bus on the Modular board.

Clock

Dedicated bus for all the clock devices supporting I2C on both Modular and Carrier boards.
