Analog Devices Inc. DC1763A-E

Overview

DC1763A-E from Analog Devices (formerly Linear Technology) is a fully populated, ready-to-use evaluation board for the LTC2192 - a 16-bit, 65Msps dual-channel simultaneous-sampling analog-to-digital converter. It features serial LVDS outputs, 77dB SNR, 90dB SFDR, ultralow 0.07psRMS jitter, and operates from a single 1.8V supply. Designed for high-fidelity digitization of IF signals in software-defined radios and portable medical imaging systems.

For engineers reviewing the DC1763A-E datasheet, DC1763A-E pinout, DC1763A-E application, or DC1763A-E equivalent, this page delivers verified board-level specifications, signal integrity validation methods, FPGA interface timing guidance, and direct alternatives for ADC evaluation platform migration or production reference design reuse.

Technical Context

The DC1763A-E implements the LTC2192 in its highest-speed grade (65Msps), with differential analog input paths optimized for 550MHz full-power bandwidth and ±1V to ±2V selectable input range. It integrates precision clock conditioning circuitry, on-board 1.8V LDOs, and configurable LVDS output drive strength (1.75mA/3.5mA) with internal 100Ω termination.

Board-level architecture supports both serial SPI configuration and parallel mode control via jumpers; includes calibrated reference voltage sources (VREF = 1.25V, VCM = 0.9V), low-noise power sequencing, and impedance-controlled 100Ω differential LVDS traces routed to a Samtec QSH connector for direct FPGA or logic analyzer interfacing.

FAQ

What is the primary function of the DC1763A-E evaluation board?

The DC1763A-E evaluation board is a complete hardware platform designed specifically to evaluate the LTC2192 dual-channel 16-bit 65Msps ADC. It provides all necessary power regulation, clock conditioning, analog input conditioning, and LVDS output routing - enabling immediate functional validation and performance characterization without custom PCB design. The DC1763A-E allows engineers to verify timing margins, SNR/SFDR, and FPGA interface compatibility before committing to system-level integration.

Does the DC1763A-E support both differential and single-ended encode clock inputs?

Yes, the DC1763A-E supports both differential and single-ended encode clock configurations for the LTC2192. When ENC– is tied to ground (via jumper), the board operates in single-ended mode compatible with TTL/CMOS clocks. With ENC+ and ENC– driven differentially (e.g., LVDS or sine wave), it achieves optimal jitter performance (0.07psRMS). The board includes matching network components and termination options for either configuration, as validated in the DC1763A-E user guide.

Can the DC1763A-E be used with Xilinx or Intel FPGAs out of the box?

Yes, the DC1763A-E is directly compatible with Xilinx Kintex/Virtex and Intel Stratix/Arria FPGAs via its Samtec QSH-060 connector. Its LVDS outputs meet ANSI/TIA-644-A electrical standards, and timing parameters (e.g., tDATA, tFRAME, pipeline latency = 7 cycles) are fully documented for FPGA IP core integration. Reference HDL code and constraint files for both vendor toolchains are provided in the DC1763A-E design package.

What analog input signal levels does the DC1763A-E support?

The DC1763A-E supports selectable differential input ranges of 1VP-P or 2VP-P through the LTC2192's SENSE pin configuration. With SENSE tied to VDD, the board uses the internal reference for ±1V range; with SENSE grounded, it configures for ±0.5V. An external reference (0.625V–1.3V) applied to SENSE sets ±0.8×VSENSE range. Input networks include 50Ω AC-coupled SMA connectors and transformer-based baluns for optimal common-mode rejection.

Is the DC1763A-E RoHS-compliant and lead-free?

Yes, the DC1763A-E is RoHS-compliant and features lead-free finish on all components and PCB surfaces. It adheres to Analog Devices' standard environmental compliance requirements, including exemption 7a (lead in high-melting-temperature type solders) where applicable for thermal reliability. Full material declarations and certificate of compliance are available upon request from Aetrix Electronics.
