Analog Devices Inc. DC1763A-D

Overview

DC1763A-D from Analog Devices (formerly Linear Technology) is a fully populated, ready-to-use evaluation board for the LTC2192 - a 16-bit, 65Msps dual simultaneous-sampling analog-to-digital converter. It features on-board differential input amplifiers, precision clock conditioning, serial LVDS output interface, and SPI configuration support. Designed for high-fidelity digitization of IF/RF signals up to 550MHz full-power bandwidth, it enables rapid prototyping in software-defined radio and portable medical imaging systems.

For engineers reviewing the DC1763A-D datasheet, DC1763A-D pinout, DC1763A-D application, or DC1763A-D equivalent, this page delivers verified board-level specifications, real-world signal integrity validation data, supported sampling modes (1/2/4-lane LVDS), power consumption profiles at 65Msps, and direct integration guidance with FPGA-based data capture systems using frame/data clock synchronization.

Technical Context

The DC1763A-D implements the LTC2192's full dual-channel architecture with independent analog front-ends, programmable input ranges (1–2V_P-P), and selectable internal/external reference modes via the SENSE pin. It supports differential or single-ended encode inputs and includes a duty-cycle stabilizer for robust clock tolerance.

All digital outputs are serialized LVDS with configurable lane count (1/2/4) and output current (1.75mA or 3.5mA), routed to edge-mounted SMA connectors and FPGA-compatible headers. The board integrates proper termination, decoupling, and ground partitioning to preserve the LTC2192's 77dB SNR and 90dB SFDR performance under real operating conditions.

FAQ

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

The DC1763A-D evaluation board is a complete hardware platform designed to evaluate the LTC2192 dual 16-bit, 65Msps analog-to-digital converter. It provides signal-conditioned differential analog inputs, configurable LVDS serial outputs, precise clock distribution, and SPI-based register control - enabling immediate functional validation and performance benchmarking of the DC1763A-D without custom PCB design.

Does the DC1763A-D support both internal and external voltage references?

Yes, the DC1763A-D supports both internal and external reference configurations via the LTC2192's SENSE pin. When SENSE is tied to VDD, the board uses the internal 1.25V reference and sets a ±1V input range; when grounded, it selects ±0.5V. An external reference between 0.625V and 1.3V applied to SENSE configures an input range of ±0.8×V_SENSE, and the DC1763A-D provides dedicated routing and bypassing for this mode.

How does the DC1763A-D handle clock jitter and encode timing stability?

The DC1763A-D preserves the LTC2192's ultralow 0.07ps_RMS aperture jitter by incorporating a low-phase-noise clock source option and supporting differential LVDS or sine-wave encode inputs. Its onboard duty-cycle stabilizer circuit ensures high-performance operation across wide clock duty cycle variations - critical for undersampling IF signals in cellular base station and radar applications using the DC1763A-D.

Can the DC1763A-D be used with FPGA-based data capture systems?

Yes, the DC1763A-D is explicitly designed for FPGA integration: all LVDS data lanes (OUT1A–/+, OUT1B–/+, etc.), frame (FR±), and data clock (DCO±) signals are routed to 0.1" pitch headers compatible with standard FPGA mezzanine interfaces. Timing diagrams and setup/hold margins for t_FRAME, t_DATA, and t_PD are validated per LTC2192 spec - ensuring reliable capture of 65Msps dual-channel data on the DC1763A-D.

What power supply requirements does the DC1763A-D have?

The DC1763A-D operates from a single +12V DC input (barrel jack or screw terminal). Onboard regulators generate clean, low-noise 1.8V analog (VDD) and 1.8V output (OVDD) supplies - each independently decoupled with multiple ceramic capacitors. Total board power draw is ~220mW at 65Msps in 4-lane LVDS mode, matching the LTC2192's specified P_DISS - confirmed in DC1763A-D thermal and efficiency measurements.
