Analog Devices Inc. AD9211-200EBZ

Overview

AD9211-200EBZ from Analog Devices is a 10-bit, 200 MSPS analog-to-digital converter evaluation board designed for high-performance wideband signal acquisition. It implements the AD9211-200 ADC in a 56-lead LFCSP package, featuring LVDS output (ANSI-644), 700 MHz full-power analog bandwidth, 1.8 V dual-supply operation, and on-chip reference with integrated track-and-hold-enabling direct interface to FPGAs in radar IF sampling and cable reverse-path systems.

For engineers reviewing the AD9211-200EBZ datasheet, AD9211-200EBZ pinout, AD9211-200EBZ application, or AD9211-200EBZ equivalent, key selection criteria include its 200 MSPS sample rate, SNR of 59.5 dBFS at 10.3 MHz input, ENOB of 9.8 bits, programmable input range (1.0–1.5 V p-p), and DDR/SDR LVDS output mode configurability via SPI.

Technical Context

The AD9211-200EBZ hosts the AD9211-200 monolithic pipelined ADC core, which uses a front-end sample-and-hold amplifier followed by multi-stage residue amplification and digital error correction. Its architecture delivers 7-cycle latency and supports both single-data-rate (SDR) and double-data-rate (DDR) LVDS output modes, with clock duty cycle stabilization and integrated data capture clock (DCO±) for timing-critical FPGA interfacing.

It operates from 1.8 V AVDD and DRVDD supplies, accepts differential analog inputs (VIN±) with programmable common-mode voltage (~1.4 V), and provides serial port control (SPI) for configuring data format (offset binary/twos complement/Gray), power-down, gain adjust, and test pattern generation-without requiring external decoupling for the on-chip reference.

FAQ

What is the maximum sample rate supported by the AD9211-200EBZ?

The AD9211-200EBZ implements the AD9211-200 ADC, which is rated for a maximum conversion rate of 200 MSPS. This is a fixed specification for this variant-unlike the AD9211-250 or AD9211-300 versions-and is validated across the industrial temperature range (−40°C to +85°C) with full AC performance including 59.5 dBFS SNR at 10.3 MHz.

Does the AD9211-200EBZ require an external reference voltage?

No, the AD9211-200EBZ does not require an external reference voltage. The underlying AD9211-200 IC integrates a precision voltage reference and track-and-hold amplifier, eliminating external decoupling components. The evaluation board routes the internal reference to the CML pin, which can be used to bias external input networks or left unconnected.

Can the AD9211-200EBZ operate in DDR LVDS mode?

Yes, the AD9211-200EBZ supports both SDR and DDR LVDS output modes. DDR mode is enabled via SPI register configuration (address 0x08, bit 4). In DDR mode, pins D0–D4 carry LSBs on one clock edge and D5–D9 carry MSBs on the opposite edge, reducing FPGA pin count by half while maintaining 200 MSPS throughput.

What is the analog input bandwidth of the AD9211-200EBZ?

The AD9211-200EBZ features a 700 MHz full-power analog bandwidth, verified at 25°C with a 1.25 V p-p differential input. This enables faithful digitization of IF signals up to 170 MHz with less than 0.5 dB amplitude droop, supporting undersampling architectures in radar and broadband test equipment.

How is the overrange detection implemented on the AD9211-200EBZ?

The AD9211-200EBZ provides dedicated OR+ and OR− LVDS outputs that assert high when the absolute value of the differential analog input exceeds the programmed full-scale range. These signals are synchronous to the DCO± clock and can be routed directly to FPGA logic for real-time gain control or clipping indication without software overhead.
