Analog Devices Inc. AD9287-100EBZ

Overview

AD9287-100EBZ from Analog Devices is a quad-channel, 8-bit, 100 MSPS serial LVDS analog-to-digital converter (ADC) with on-chip sample-and-hold, 295 MHz full-power analog bandwidth, 2 V p-p differential input range, and 1.8 V single-supply operation. It delivers SNR = 49 dB and ENOB = 7.85 bits at Nyquist, targeting high-density data acquisition in portable ultrasound and digital beam-forming systems.

For engineers reviewing the AD9287-100EBZ datasheet, AD9287-100EBZ pinout, AD9287-100EBZ application, or AD9287-100EBZ equivalent, this evaluation board enables rapid validation of quad-channel LVDS ADC performance, clock/data alignment, serial test pattern generation, and low-power channel power-down modes in medical imaging and quadrature radio receiver designs.

Technical Context

The AD9287-100EBZ implements a pipelined ADC architecture with three sections: a 4-bit first stage, eight 1.5-bit stages, and a final 3-bit flash stage, using 1-bit redundancy per stage for digital error correction. Sampling occurs on the rising edge of the LVPECL/LVDS/CMOS-compatible clock input.

It integrates four independent pipeline ADCs sharing a common clock domain, each with programmable output resolution, flexible bit orientation (MSB/LSB first), and serial LVDS outputs compliant with ANSI-644. The board provides DCO± and FCO± signals for DDR data capture and frame synchronization, with pipeline latency fixed at 8 clock cycles.

FAQ

What is the primary function of the AD9287-100EBZ evaluation board?

The AD9287-100EBZ is an evaluation board for the AD9287 quad, 8-bit, 100 MSPS serial LVDS ADC. It provides complete hardware and software infrastructure-including clock conditioning, analog input drive, LVDS output termination, and SPI interface-to validate timing margins, SNR/SFDR performance, channel crosstalk (−100 dB), and serial data integrity under real-world conditions. The board directly supports the AD9287's full feature set, including programmable clock/data alignment and built-in test pattern generation.

Does the AD9287-100EBZ support individual channel power-down?

Yes, the AD9287-100EBZ enables individual-channel power-down via the AD9287's PDWN pin and SPI control. When all four channels are disabled, power dissipation drops to ≤4 mW, and wake-up time from power-down is 375 μs. This capability is fully implemented and tested on the board, allowing engineers to verify dynamic power scaling for battery-operated portable ultrasound systems.

What clock sources are compatible with the AD9287-100EBZ?

The AD9287-100EBZ accepts LVPECL, LVDS, or CMOS clock inputs on CLK± pins, supporting frequencies from 10 MSPS to 100 MSPS. The board includes onboard clock conditioning circuitry and jumper-selectable termination to maintain signal integrity. The AD9287 automatically multiplies the input clock for LVDS serialization, and the board exposes DCO± and FCO± outputs synchronized to sampled data for precise DDR capture timing.

Can the AD9287-100EBZ be used to evaluate different output formats?

Yes, the AD9287-100EBZ supports both standard ANSI-644 LVDS (247–454 mV differential swing) and low-power reduced-swing LVDS (150–250 mV), configurable via SPI register settings. It also supports MSB-first or LSB-first serial data ordering and programmable output resolution-features validated on the board through its SPI interface and FPGA-based data capture logic.

Is the AD9287-100EBZ RoHS compliant and qualified for industrial temperature operation?

Yes, the AD9287-100EBZ evaluates the AD9287 IC, which is packaged in a RoHS-compliant 48-lead LFCSP and specified over the industrial temperature range of −40°C to +85°C. The evaluation board itself uses RoHS-compliant components and PCB materials, and its design accommodates thermal validation across this full range using calibrated environmental chambers and on-board temperature sensors.
