Analog Devices Inc. AD9249-65EBZ

Overview

AD9249-65EBZ from Analog Devices is a 16-channel, 14-bit, 65 MSPS serial LVDS analog-to-digital converter operating from a single 1.8 V supply, featuring 75 dBFS SNR and 90 dBc SFDR at Nyquist, with integrated sample-and-hold and on-chip 1.0 V reference - deployed in multichannel medical imaging front-ends requiring high-density, low-power digitization.

For engineers reviewing the AD9249-65EBZ datasheet, AD9249-65EBZ pinout, AD9249-65EBZ application, or AD9249-65EBZ equivalent, this evaluation board enables rapid validation of 16-channel synchronized sampling, LVDS DDR data capture timing, crosstalk performance (<−90 dB), and SPI-configurable power modes across industrial temperature range (−40°C to +85°C).

Technical Context

The AD9249-65EBZ implements a fully integrated 16-channel ADC architecture with independent analog input pairs (VIN±A1–H2), dual LVDS serial output banks (D±x1/D±x2), and dedicated frame/data clock outputs (FCO±1/2, DCO±1/2) supporting DDR operation up to 455 MHz. Each channel includes programmable clock/data alignment and individual power-down control.

It uses an internal 1.0 V reference with 0.98–1.01 V tolerance, supports 2 V p-p differential analog input range, and achieves 135 fs rms aperture jitter. The device auto-multiplies the input clock for LVDS serialization and provides built-in deterministic/pseudorandom test pattern generation via SPI.

FAQ

What is the primary function of the AD9249-65EBZ evaluation board?

The AD9249-65EBZ is an evaluation board for the AD9249-65EBZ 16-channel, 14-bit, 65 MSPS ADC. It provides complete signal chain access - including analog inputs, LVDS serial outputs, SPI interface, and clock distribution - enabling engineers to validate timing, noise, crosstalk, and system-level synchronization before integrating the AD9249-65EBZ into final hardware.

Does the AD9249-65EBZ support configurable LVDS output voltage levels?

Yes, the AD9249-65EBZ supports two LVDS output modes: standard ANSI-644 (281–422 mV differential swing) and low-power reduced-swing mode (150–250 mV). Mode selection is controlled via SPI register configuration, allowing trade-offs between signal integrity and power consumption based on PCB layout and receiver compatibility.

How many analog input channels does the AD9249-65EBZ evaluate, and what is their arrangement?

The AD9249-65EBZ evaluates all 16 analog input channels of the underlying AD9249 IC, organized as eight differential pairs per bank (Bank 1: A1–H1; Bank 2: A2–H2), each with dedicated VIN± pins. This structure supports true simultaneous sampling across all channels with matched propagation delay and gain/offset matching within ±0.9 LSB INL.

Can the AD9249-65EBZ operate without an external reference or driver circuitry?

Yes, the AD9249-65EBZ leverages the AD9249's internal 1.0 V reference and requires no external reference or analog driver components for basic operation. Its 2 V p-p input range and 0.9–1.3 V common-mode window accommodate direct connection to transformers, baluns, or op-amp drivers - simplifying front-end design in compact systems.

What clocking options are supported by the AD9249-65EBZ for the AD9249 core?

The AD9249-65EBZ accepts LVPECL-, CMOS-, or LVDS-compatible differential clock inputs (CLK±) from 10 MHz to 520 MHz. The AD9249 core automatically multiplies the input clock to generate appropriate LVDS serialization rates, and the board provides termination and AC-coupling options to maintain signal integrity across frequency bands.
