Analog Devices Inc. DC1751A-C

Overview

DC1751A-C from Analog Devices is an evaluation board for the LTM9011-14 - an 8-channel, 14-bit, 125Msps simultaneous-sampling ADC with serial LVDS outputs, 73.1dB SNR, 88dB SFDR, and integrated bypass capacitance in a 140-pin BGA package. It enables high-fidelity digitization of wideband RF signals in multichannel SDR and medical imaging systems.

For engineers reviewing the DC1751A-C datasheet, DC1751A-C pinout, DC1751A-C application, or DC1751A-C equivalent, this page provides verified board-level specifications, supported ADC configuration modes (1-/2-lane LVDS, differential/single-ended clock), analog input range selection (1–2V_P-P), SPI register access, and thermal/power management details for rapid prototyping and system integration.

Technical Context

The DC1751A-C implements a complete signal chain interface for the LTM9011-14, including precision AC-coupled analog input paths with matched 50Ω terminations, low-jitter differential clock conditioning circuitry, configurable LVDS output termination, and on-board SPI programming via USB-to-SPI bridge. It supports all three speed grades (LTM9011/LTM9010/LTM9009) through jumper-selectable power and timing configurations.

Board-level design incorporates flow-through pinout routing, internal ground plane segmentation for analog/digital isolation, and thermal vias under the ADC BGA to maintain junction temperature below 150°C at full sample rate. The layout adheres to strict controlled-impedance routing (100Ω differential, 50Ω single-ended) for all high-speed analog and LVDS traces.

FAQ

What is the primary function of the DC1751A-C evaluation board?

The DC1751A-C evaluation board is a fully populated, ready-to-run hardware platform for evaluating the LTM9011-14, LTM9010-14, and LTM9009-14 octal 14-bit ADCs. It provides all necessary signal conditioning, clock distribution, power regulation, and SPI interface logic to validate performance metrics-including SNR, SFDR, and channel matching-at full sample rates up to 125Msps without custom PCB design.

Does the DC1751A-C support both 1-lane and 2-lane LVDS output modes for the LTM9011-14?

Yes, the DC1751A-C supports both 1-lane and 2-lane LVDS serialization modes for the LTM9011-14. Mode selection is implemented via on-board jumpers that configure the PAR/SER pin and CS/SCK logic states per the LTM9011-14 datasheet. The board routes all 16 LVDS output pairs (OUT1A/B through OUT8A/B) with proper termination and impedance control for either mode.

Can the DC1751A-C be used to evaluate the LTM9010-14 and LTM9009-14 as well as the LTM9011-14?

Yes, the DC1751A-C is compatible with all three members of the LTM90xx-14 family: LTM9011-14 (125Msps), LTM9010-14 (105Msps), and LTM9009-14 (80Msps). Power sequencing, clock interface, and SPI register map are identical across the family, and the board's firmware and hardware design accommodate the full range of sampling frequencies and current consumption profiles.

What software tools are required to configure and capture data from the DC1751A-C?

The DC1751A-C uses Analog Devices' ACE (Analysis, Control, Evaluation) software, which provides GUI-based register configuration, real-time FFT analysis, histogram plotting, and raw data capture to CSV. ACE communicates with the board via the onboard FTDI USB-to-SPI bridge and supports Windows OS with no additional drivers beyond standard FTDI VCP installation.

Does the DC1751A-C include provisions for external reference voltage or only use the LTM9011-14's internal reference?

The DC1751A-C supports both internal and external reference configurations. It includes a dedicated SMA connector and precision resistor network for applying an external 0.625V–1.3V reference to the SENSE pin, enabling gain calibration and improved full-scale stability. Default operation uses the LTM9011-14's internal 1.25V reference, but the board allows seamless switching via solder jumper.
