Analog Devices Inc. DC1751A-B

Overview

DC1751A-B from Analog Devices is a high-performance 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 - designed for wideband communications and multichannel data acquisition systems.

For engineers reviewing the DC1751A-B datasheet, DC1751A-B pinout, DC1751A-B application, or DC1751A-B equivalent, this page delivers verified board-level specifications, supported ADC configuration modes (1-/2-lane LVDS, 12/14/16-bit serialization), clock interface options (differential/single-ended ENC±), analog input range selection (1–2VP-P), and thermal/power management features critical for SDR, medical imaging, and test equipment design.

Technical Context

The DC1751A-B implements full signal-chain support for the LTM9011-14, including precision differential analog input conditioning with on-board transformer-coupled and AC-coupled paths, programmable common-mode bias via VCM outputs, and configurable LVDS output termination. It supports all three speed grades (LTM9011/LTM9010/LTM9009) via jumper-selectable power and timing settings.

Board-level SPI interface enables real-time register configuration of sampling mode, serialization format, output current (1.75mA/3.5mA), shutdown/Nap modes, and internal reference selection. Clock distribution includes SMA inputs for ENC±, on-board crystal oscillator option, and duty-cycle stabilizer enable/disable control - all validated per LTM9011-14's ±0.15psRMS aperture jitter spec at 125Msps.

FAQ

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

The DC1751A-B evaluation board is a fully assembled and tested platform for evaluating the LTM9011-14 octal ADC. It provides complete analog input conditioning, clock distribution, LVDS output interfacing, and SPI-based configuration - enabling immediate functional validation and performance characterization of the DC1751A-B without custom PCB design.

Which ADC variants are supported by the DC1751A-B?

The DC1751A-B supports all three members of the LTM90xx-14 family: LTM9011-14 (125Msps), LTM9010-14 (105Msps), and LTM9009-14 (80Msps). Jumper configurations allow correct power sequencing, clock setup, and serialization mode selection for each speed grade - confirmed via Analog Devices' official DC1751A-B user guide.

Does the DC1751A-B support both differential and single-ended clock inputs?

Yes, the DC1751A-B supports both differential (ENC+/ENC– via SMA) and single-ended (ENC+ only, ENC– tied to GND) clock drive modes for the LTM9011-14. The board includes on-board resistive termination and configurable biasing to maintain signal integrity across both modes - matching the LTM9011-14's specified 0.2–3.6V input voltage range and ±0.15psRMS jitter performance.

How does the DC1751A-B handle analog input common-mode voltage?

The DC1751A-B routes the LTM9011-14's four VCM outputs (VCM14, VCM23, VCM58, VCM67) to dedicated on-board bias networks, providing precise 0.9V common-mode voltage (at VDD = 1.8V) to each channel pair. This eliminates need for external bias components and ensures compliance with the LTM9011-14's ±100mV common-mode rejection spec over temperature.

Can the DC1751A-B be used with FPGA development kits?

Yes, the DC1751A-B is designed for direct connection to FPGA carrier boards via its 2×20-pin LVDS expansion header (3.5mA or 1.75mA mode selectable), supporting standard 100Ω differential termination. Its serialized LVDS output format, frame/DCO synchronization signals, and pipeline latency of 6 cycles are fully documented in the LTM9011-14 datasheet and validated on Xilinx Kintex-7 and Intel Arria 10 platforms.
