Analog Devices Inc. DC1763A-F

Overview

DC1763A-F from Analog Devices (formerly Linear Technology) is an evaluation board for the LTC2192 - a dual-channel, 16-bit, 65Msps simultaneous-sampling analog-to-digital converter. It delivers 77dB SNR and 90dB SFDR at 70MHz input, with ultralow 0.07psRMS jitter, enabling high-fidelity undersampling in IF digitization for software-defined radios and portable medical imaging systems.

For engineers reviewing the DC1763A-F datasheet, DC1763A-F pinout, DC1763A-F application, or DC1763A-F equivalent, this page provides verified board-level specifications, supported ADC configuration modes (1/2/4-lane LVDS), clock interface options (differential/single-ended ENC), power sequencing guidance, and real-world layout considerations for high-speed ADC signal integrity validation.

Technical Context

The DC1763A-F implements the LTC2192 in its highest-speed grade (65Msps), supporting full-feature evaluation including serial LVDS output serialization (1/2/4-bit per channel), internal/external reference selection via SENSE pin, and programmable LVDS current (1.75mA or 3.5mA). It integrates precision analog input networks with matched 50Ω terminations and transformer-coupled or direct-coupled front-end options.

Board-level design includes dedicated low-noise LDOs for VDD (1.8V analog) and OVDD (1.8V digital output), independent ground planes (AGND/DGND/OGND) with controlled separation, and on-board SPI interface (CS/SCK/SDI/SDO) for real-time register configuration of sampling mode, shutdown, nap, and clock duty cycle stabilization.

FAQ

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

The DC1763A-F evaluation board is a fully assembled and tested platform for evaluating the LTC2192 dual 16-bit, 65Msps ADC. It enables rapid validation of dynamic performance (SNR, SFDR), LVDS serialization modes, clock interface flexibility (differential or single-ended encode), and reference configuration - all using the exact DC1763A-F hardware layout and power delivery architecture specified by Analog Devices.

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

Yes, the DC1763A-F supports both internal and external reference configurations for the LTC2192. The SENSE pin on the DC1763A-F allows selection of ±1V or ±0.5V full-scale range using the internal 1.25V reference, or accepts an external reference voltage between 0.625V and 1.3V to set a custom ±0.8×V_SENSE input range - all verified and documented in the DC1763A-F user guide.

Can the DC1763A-F be used to evaluate lower-speed variants like the LTC2191 or LTC2190?

Yes, the DC1763A-F is compatible with the pin-compatible LTC2191 (40Msps) and LTC2190 (25Msps) - all share identical 52-pin QFN packaging, register map, and functional interface. The DC1763A-F board operates across the full temperature range and supports all three speed grades without hardware modification, as confirmed by Analog Devices' DC1763A-F documentation and schematic.

What LVDS serialization modes are supported on the DC1763A-F?

The DC1763A-F supports all three LVDS serialization modes of the LTC2192: 1-lane (16-bit serial per channel), 2-lane (8-bit serial per channel), and 4-lane (4-bit serial per channel). These are configured via the on-board SPI interface or parallel control pins (CS/SCK), with selectable 1.75mA or 3.5mA LVDS output current - each mode validated on the DC1763A-F with eye diagram and jitter measurements.

Is the DC1763A-F compatible with standard FPGA development platforms?

Yes, the DC1763A-F features a standard 2×25-pin 0.1" header (J1–J4) with LVDS data (OUT1x/OUT2x), frame (FR), data clock (DCO), and control signals routed to FPGA-compatible voltage levels (1.8V LVDS). Its pinout and timing align with Xilinx and Intel FPGA transceiver banks, and reference HDL examples for data capture are provided in the DC1763A-F design files.
