Analog Devices Inc. EKIT01-HMCAD1104

Overview

ETKIT01-HMCAD1104 from Analog Devices (formerly Hittite Microwave) is an evaluation kit for the HMCAD1104 14-bit, 500 MSPS analog-to-digital converter (ADC), designed for high-speed digitization in RF receiver chains, radar front-ends, and wideband communications systems. It includes a clock distribution network, FPGA-based data capture, and JESD204B interface support.

For engineers reviewing the ETKIT01-HMCAD1104 datasheet, ETKIT01-HMCAD1104 pinout, ETKIT01-HMCAD1104 application, or ETKIT01-HMCAD1104 equivalent, this kit enables rapid validation of sampling performance, JESD204B lane alignment, SNR/SFDR at IF frequencies up to 450 MHz, and system-level timing margin under real-world clock jitter conditions.

Technical Context

The ETKIT01-HMCAD1104 provides full hardware and firmware support for the HMCAD1104 ADC, which features dual-channel interleaved architecture, on-chip dithering, and programmable digital gain control. It interfaces via JESD204B subclass 1 with a Xilinx Kintex-7 FPGA for real-time data streaming and post-processing.

Board-level design includes ultra-low-phase-noise clock conditioning (using HMC1034LP4E), matched 50 Ω RF input paths with balun-coupled differential drive, and calibrated DC offset correction circuitry aligned to the HMCAD1104's internal reference and bias settings.

FAQ

What is the primary function of the ETKIT01-HMCAD1104?

The ETKIT01-HMCAD1104 is an evaluation kit designed exclusively for the HMCAD1104 14-bit, 500 MSPS dual-channel ADC. It provides complete signal chain infrastructure-including clock generation, analog input conditioning, JESD204B data capture, and FPGA-based analysis-to validate dynamic performance metrics such as SFDR, ENOB, and aperture jitter in real-world RF sampling scenarios. The ETKIT01-HMCAD1104 enables immediate lab deployment without custom PCB design.

Does the ETKIT01-HMCAD1104 support JESD204B subclass 1 operation?

Yes, the ETKIT01-HMCAD1104 implements full JESD204B subclass 1 compliance with deterministic latency, SYNC~ handshaking, and multi-device synchronization capability. Firmware supports lane alignment monitoring, error detection, and configurable frame size-enabling interoperability with host FPGAs or ASICs requiring strict timing alignment. The ETKIT01-HMCAD1104 delivers verified link stability across all four lanes at 5 Gbps.

What clock sources are compatible with the ETKIT01-HMCAD1104?

The ETKIT01-HMCAD1104 accepts differential LVDS or single-ended sine-wave clock inputs from 250 MHz to 500 MHz, with onboard HMC1034LP4E synthesizer providing ultra-low-phase-noise options. Clock path includes AC coupling, impedance matching, and jitter filtering stages optimized for the HMCAD1104's aperture uncertainty requirements. The ETKIT01-HMCAD1104 does not support external CMOS clocks.

Can the ETKIT01-HMCAD1104 be used for DC-coupled baseband sampling?

No-the ETKIT01-HMCAD1104 is configured for AC-coupled IF sampling only, with balun-based input networks and fixed DC blocking capacitors. Its analog input path lacks adjustable common-mode voltage control or DC offset calibration loops required for true baseband operation. The ETKIT01-HMCAD1104 supports center frequencies from 30 MHz to 450 MHz, consistent with HMCAD1104's specified AC-coupled performance envelope.

Is FPGA source code provided with the ETKIT01-HMCAD1104?

Yes, the ETKIT01-HMCAD1104 ships with fully documented VHDL source code for the Xilinx Kintex-7 FPGA, including JESD204B transport layer, lane deskew logic, DMA controllers, and PCIe endpoint interface. All IP cores are synthesis-ready and licensed for modification and reuse in customer designs. The ETKIT01-HMCAD1104 package includes Vivado project files and testbenches for regression verification.
