Analog Devices Inc. EVAL01-HMCAD1520

Overview

EVAL01-HMCAD1520 from Analog Devices is an evaluation board for the HMCAD1520 - a high-speed, multi-mode 8/12/14-bit ADC supporting up to 1000 MSPS (single-channel), 640 MSPS (dual-channel), and 105 MSPS (quad-channel precision mode), with serial LVDS output, integrated crosspoint switch, and 1.8 V supply. It enables rapid prototyping of wideband signal acquisition in test instrumentation and communications receivers.

For engineers reviewing the EVAL01-HMCAD1520 datasheet, EVAL01-HMCAD1520 pinout, EVAL01-HMCAD1520 application, or EVAL01-HMCAD1520 equivalent, this board provides full access to the HMCAD1520's configurable sampling modes, SPI register control, LVDS timing interfaces, and power management features - critical for validating high-fidelity digitization in oscilloscope front-ends, spectrum analyzers, and ultrasound beamformers.

Technical Context

The EVAL01-HMCAD1520 implements a complete reference design for the HMCAD1520 ADC, including low-jitter clock conditioning circuitry, matched 50 Ω differential analog input paths for all four channels (IP1/IN1 through IP4/IN4), and fully terminated LVDS data/lane/frame clock outputs compliant with RSDS/LVDS standards. It supports all operational modes - single/dual/quad high-speed and 14-bit precision - via on-board jumpers and SPI configuration.

Board-level features include on-board 1.8 V LDOs for AVDD/DVDD/OVDD domains, dedicated ground planes per supply domain, calibrated reference voltage generation, and a USB-to-SPI interface bridge for register programming and real-time mode switching without external controllers. The layout adheres to strict high-speed ADC layout guidelines, including controlled-impedance routing and isolation between analog/digital sections.

FAQ

What is the primary function of the EVAL01-HMCAD1520 evaluation board?

The EVAL01-HMCAD1520 evaluation board is a fully configured hardware platform for evaluating the HMCAD1520 high-speed multi-mode ADC. It provides immediate access to all four differential analog inputs, LVDS data outputs, clock interfaces, and SPI register control - enabling engineers to validate dynamic performance (SNR, SFDR), timing behavior, and mode-switching functionality without custom PCB design. The board ships with firmware and PC software for real-time configuration of the HMCAD1520.

Does the EVAL01-HMCAD1520 support all HMCAD1520 operating modes?

Yes, the EVAL01-HMCAD1520 supports every documented mode of the HMCAD1520: single-channel (up to 1000 MSPS), dual-channel (up to 640 MSPS), quad-channel high-speed (up to 160 MSPS), and 14-bit precision mode (up to 105 MSPS). Mode selection is performed via SPI register writes using the included USB-to-SPI interface - no hardware modifications are required to switch between modes or configure LVDS output format (12/14/16-bit or dual-8-bit).

How is clocking implemented on the EVAL01-HMCAD1520 board?

The EVAL01-HMCAD1520 provides flexible clocking options: a low-phase-noise onboard crystal oscillator (100 MHz), SMA input for external differential clock (LVDS/LVPECL/sine), and internal programmable clock divider within the HMCAD1520 itself. The board routes CLKP/CLKN directly to the ADC with impedance-matched 100 Ω differential traces and includes termination options. Jitter performance is optimized for <130 fsrms aperture jitter in precision mode, verified per HMCAD1520 datasheet test conditions.

Can the EVAL01-HMCAD1520 be used with FPGA-based data capture systems?

Yes - the EVAL01-HMCAD1520 is explicitly designed for seamless integration with FPGA development platforms. Its LVDS outputs (data lanes, LCLK, FCLK) comply with standard RSDS/LVDS electrical specifications and timing margins, and the board includes pin-compatible headers matching common FPGA mezzanine interfaces. Reference HDL code and timing constraints for Xilinx and Intel FPGAs are provided in the Analog Devices evaluation kit documentation for the EVAL01-HMCAD1520.

What power supply requirements does the EVAL01-HMCAD1520 have?

The EVAL01-HMCAD1520 operates from a single 5 V USB supply (for basic evaluation) or an external 5 V/3 A DC source via screw terminal. On-board LDOs generate clean, isolated 1.8 V rails for AVDD, DVDD, and OVDD as required by the HMCAD1520. Total board power consumption ranges from ~1.2 W (all channels active, 640 MSPS) to ~0.15 W (deep sleep). Thermal design includes copper pours and vias to maintain junction temperature below 70 °C under continuous operation.
