FAQ

What is the primary function of the AD-FMCOMMS4-EBZ?

The AD-FMCOMMS4-EBZ is an FMC-compatible evaluation board built around the AD9364 RF Agile Transceiver. Its primary function is to provide a fully validated, ready-to-use hardware platform for developing and testing SDR applications - including baseband algorithm verification, RF performance characterization, and system-level interoperability checks - without requiring custom PCB design. The AD-FMCOMMS4-EBZ enables immediate connection to Xilinx Zynq-based carrier boards via its LPC connector.

Which carrier boards are compatible with the AD-FMCOMMS4-EBZ?

The AD-FMCOMMS4-EBZ is mechanically and electrically compliant with the VITA 57.1 FMC LPC standard and has been validated with Xilinx ZC706, ZCU102, KC705, and ZedBoard carrier cards. Compatibility requires proper FPGA pinout mapping to the AD9364's CMOS or LVDS data buses, SPI interface, and control signals - all documented in the AD-FMCOMMS4-EBZ user guide and HDL reference designs provided by Analog Devices.

Does the AD-FMCOMMS4-EBZ support both TDD and FDD operation?

Yes, the AD-FMCOMMS4-EBZ supports both TDD and FDD operation through the underlying AD9364 transceiver. Hardware-level TDD/FDD mode selection is controlled via the TXNRX and ENABLE pins, which are routed to FPGA GPIO on the carrier board. The board's firmware and reference designs include preconfigured state machines for both modes, and multichip synchronization (via SYNC_IN/CLK_OUT) is fully functional in either configuration.

What RF performance metrics are achievable with the AD-FMCOMMS4-EBZ?

Measured RF performance matches AD9364 datasheet specifications: receiver noise figure <2.5 dB (800 MHz), Tx EVM ≤−40 dB, Tx noise floor ≤−157 dBm/Hz, and 66 dB dynamic range on the Tx monitor path. These values are confirmed across 70–6000 MHz using calibrated lab equipment and factory-tested AD-FMCOMMS4-EBZ units - no additional RF front-end tuning is required to achieve datasheet-grade results.

Is external clocking supported on the AD-FMCOMMS4-EBZ?

Yes, the AD-FMCOMMS4-EBZ supports both crystal (XTALP/XTALN) and external oscillator inputs for the AD9364 reference clock, with frequency range 10–80 MHz. The board includes jumpers to select between onboard 40 MHz oscillator and external clock source, and the CLK_OUT signal is accessible for daisy-chaining or multiboard synchronization - all implemented per AD9364 Rev. C clocking architecture requirements.
