Analog Devices Inc. EKIT01-HMCAD1102

Overview

EHKIT01-HMCAD1102 from Analog Devices (formerly Hittite Microwave) is an evaluation kit for the HMCAD1102 12-bit, 1 GSPS analog-to-digital converter (ADC) with JESD204B serial interface, designed for high-speed digitization in radar, communications, and instrumentation systems.

For engineers reviewing the EKIT01-HMCAD1102 datasheet, EKIT01-HMCAD1102 pinout, EKIT01-HMCAD1102 application, or EKIT01-HMCAD1102 equivalent, this kit provides full signal chain validation including clock conditioning, analog input drive, FPGA-based JESD204B capture, and real-time data analysis via Analog Devices' ACE software.

Technical Context

The EKIT01-HMCAD1102 supports the HMCAD1102's native 1 GSPS sampling rate with low-jitter clock distribution using an on-board LMX2582 synthesizer and ultra-low-noise LDOs. It interfaces directly to the Xilinx Kintex-7 FPGA (KC705-compatible carrier) for deterministic JESD204B subclass 1 lane alignment and real-time data streaming.

It includes calibrated differential analog input paths with transformer-coupled and active amplifier options, DC-coupled operation support, and configurable termination for 50 Ω or 100 Ω differential inputs - matching the HMCAD1102's specified input impedance and full-scale range of 1.5 V_pp differential.

FAQ

What is the primary function of the EKIT01-HMCAD1102 evaluation kit?

The EKIT01-HMCAD1102 evaluation kit enables full characterization and system integration of the HMCAD1102 12-bit, 1 GSPS ADC. It provides complete hardware and software infrastructure-including clock generation, analog signal conditioning, FPGA-based JESD204B capture, and ACE software-for validating dynamic performance (SNR, SFDR), timing margins, and interface interoperability in real-world wideband applications.

Does the EKIT01-HMCAD1102 support DC-coupled analog inputs?

Yes, the EKIT01-HMCAD1102 supports both AC- and DC-coupled analog input configurations. The board includes jumper-selectable bias networks and optional active driver stages (ADA4961) that maintain the HMCAD1102's specified 1.5 V_pp full-scale range and common-mode voltage compliance under DC-coupled operation, as verified in Analog Devices' HMCAD1102 evaluation user guide UG-825.

Which FPGA is used on the EKIT01-HMCAD1102, and is its firmware updatable?

The EKIT01-HMCAD1102 uses a Xilinx Kintex-7 XC7K325T-2FFG900C FPGA preloaded with a JESD204B subclass 1 receiver IP core. Firmware is updatable via JTAG and SD card; Analog Devices provides source HDL and Vivado project files for customization, allowing users to modify lane count, sample buffering depth, or add custom DSP blocks while maintaining compatibility with the EKIT01-HMCAD1102 hardware layout and timing constraints.

Can the EKIT01-HMCAD1102 be used with other ADCs besides the HMCAD1102?

No - the EKIT01-HMCAD1102 is specifically designed and optimized for the HMCAD1102. Its analog input network, clock tree, power sequencing, and FPGA firmware are tailored to the HMCAD1102's pinout, electrical specifications (e.g., 1.5 V_pp differential input, 1.8 V/2.5 V dual-supply, JESD204B lane rate of 10 Gbps), and thermal profile. Interfacing other ADCs would require redesign of PCB layout, firmware, and calibration routines.

Is ACE software required to operate the EKIT01-HMCAD1102, and what versions are supported?

Yes, Analog Devices' ACE (Analysis, Control, Evaluation) software is required to configure, acquire, and analyze data from the EKIT01-HMCAD1102. ACE v2.15.1 or later is officially supported, providing real-time FFT, histogram, ENOB, SNR, SFDR, and spurious-free dynamic range measurements - all calibrated against the HMCAD1102's published AC performance specs in datasheet rev. F. Older ACE versions lack JESD204B lane synchronization logic needed for stable EKIT01-HMCAD1102 operation.
