Analog Devices Inc. DC1369A-F

Overview

DC1369A-F from Analog Devices (formerly Linear Technology) is a high-performance evaluation board for the LTC2258-14 14-bit, 65Msps analog-to-digital converter. It supports full-rate CMOS, DDR CMOS, and DDR LVDS output modes; delivers 74dB SNR and 88dB SFDR at 70MHz input; and operates from a single 1.8V supply. Designed for RF sampling in cellular base stations and software-defined radios.

For engineers reviewing the DC1369A-F datasheet, DC1369A-F pinout, DC1369A-F application, or DC1369A-F equivalent, this page provides verified board-level specifications, supported ADC configuration modes, clock interface details, analog input layout guidance, and sourcing support for production validation and rapid prototyping of wideband data acquisition systems.

Technical Context

The DC1369A-F implements the LTC2258-14 in a 40-pin QFN package with differential analog input (AIN+/AIN–), dual-supply operation (VDD = 1.8V, OVDD = 1.2–1.8V), and configurable digital outputs. It integrates on-board clock conditioning, reference decoupling (REFH/REFL), and SPI-based register control via CS/SCK/SDI/SDO.

It supports three output configurations: full-rate CMOS (14 single-ended D0–D13 + OF), DDR CMOS (7 differential pairs), and DDR LVDS (7 differential pairs with internal 100Ω termination). The board enables evaluation of ultralow jitter (0.17psRMS), 800MHz full-power bandwidth, and optional features including clock duty cycle stabilizer and data randomizer.

FAQ

What is the primary function of the DC1369A-F evaluation board?

The DC1369A-F evaluation board is a fully assembled and tested platform for evaluating the LTC2258-14 14-bit, 65Msps analog-to-digital converter. It provides all necessary power regulation, clock conditioning, reference circuitry, and interface headers to validate AC performance (SNR, SFDR), timing behavior, and configuration flexibility of the DC1369A-F in real-world signal chain designs.

Which output interface modes does the DC1369A-F support for the LTC2258-14?

The DC1369A-F supports all three digital output configurations of the LTC2258-14: full-rate CMOS (14 single-ended data lines + OF), double-data-rate CMOS (7 differential pairs), and double-data-rate LVDS (7 differential pairs with programmable 1.75mA or 3.5mA drive strength). Mode selection is controlled via the SCK and PAR/SER pins per the DC1369A-F schematic and user guide.

How is analog input range configured on the DC1369A-F?

On the DC1369A-F, the analog input range (1VP-P to 2VP-P differential) is set by the voltage applied to the SENSE pin of the LTC2258-14. Connecting SENSE to ground selects ±0.5V internal reference (1VP-P range); connecting to VDD selects ±1V (2VP-P range); applying 0.625V–1.3V enables precise external reference scaling - all implemented directly on the DC1369A-F board using jumpers or external sources.

Does the DC1369A-F include clock conditioning circuitry?

Yes, the DC1369A-F includes dedicated clock conditioning circuitry to support low-jitter operation of the LTC2258-14. It accepts differential (LVDS/PECL) or single-ended (CMOS/TTL) clock inputs via the ENC+/ENC– pins and implements the optional clock duty cycle stabilizer (enabled via CS pin), critical for maintaining 74dB SNR at full 65Msps sample rate.

Can the DC1369A-F be used to evaluate power consumption trade-offs between output modes?

Yes, the DC1369A-F enables direct measurement of power consumption differences across output modes: full-rate CMOS (81mW), DDR CMOS (49mW), and DDR LVDS (125–161mW depending on current mode). Dedicated test points for VDD and OVDD current, along with documented thermal layout, allow engineers to quantify trade-offs between speed, noise, and power for their specific DC1369A-F implementation.
