Product details
Overview
AD9211-300EBZ from Analog Devices is a 10-bit, 300 MSPS analog-to-digital converter (ADC) with LVDS outputs, 700 MHz full-power analog bandwidth, and integrated track-and-hold and on-chip reference. It operates from a single 1.8 V supply and delivers 60.1 dBFS SNR at 70 MHz input frequency-optimized for broadband communications test equipment and radar subsystems.
For engineers reviewing the AD9211-300EBZ datasheet, AD9211-300EBZ pinout, AD9211-300EBZ application, or AD9211-300EBZ equivalent, key selection criteria include sampling rate (300 MSPS), LVDS DDR/SDR output mode support, 1.8 V dual-supply operation, aperture jitter (0.2 ps rms), and industrial temperature range (−40°C to +85°C).
Technical Context
The AD9211-300EBZ implements a pipelined switched-capacitor ADC architecture with digital error correction logic and redundant bits per stage. Sampling occurs on the rising edge of the differential clock, and latency is fixed at 7 clock cycles across all modes.
It supports both SDR and DDR LVDS output formats via SPI configuration, with programmable input voltage range (1.0–1.5 V p-p), selectable data coding (offset binary/twos complement/Gray), and integrated clock duty cycle stabilizer. The CML pin provides internal bias control for optimized analog input common-mode voltage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Sampling Rate | 300 MSPS maximum - enables digitization of wideband IF signals up to 150 MHz Nyquist zone. |
| SNR @ 70 MHz | 60.1 dBFS - ensures high-fidelity signal capture in demanding RF receiver chains. |
| Analog Bandwidth | 700 MHz - supports direct sampling of UHF and L-band signals without external amplification. |
| Power Dissipation | 410 mW in LVDS DDR mode - balances performance and thermal management in dense FPGA-based systems. |
| Input Range | Programmable 1.0–1.5 V p-p differential - simplifies interface to various RF front-end gain stages. |
| Aperture Jitter | 0.2 ps rms - limits sampling uncertainty to <0.02° phase error at 100 MHz input. |
| Digital Interface | LVDS ANSI-644 compliant - ensures robust timing margin and low EMI when interfacing to Xilinx/Kintex or Intel/Stratix FPGAs. |
Pinout & Package
The AD9211-300EBZ evaluation board implements the AD9211-300 IC in a 56-lead LFCSP package (CP-56-2), with exposed paddle soldered to AGND for thermal and electrical integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN+, VIN− | Differential analog input | Accepts 1.0–1.5 V p-p true/complement signal; CML pin configures internal bias for optimal linearity. |
| CLK+, CLK− | Differential clock input | Supports CMOS/LVDS/LVPECL; internal common-mode bias at 1.2 V enables flexible clock source integration. |
| D0+ to D9+ | LVDS data outputs (true) | Deliver 10-bit parallel samples; DDR mode maps D0–D4/D5–D9 across two edges for reduced pin count. |
| DCO+, DCO− | Data clock output | Provides synchronous LVDS clock aligned to sampled data-critical for deterministic FPGA capture timing. |
| OR+, OR− | Overrange indicator | LVDS-compliant flag signaling input saturation; configurable via SPI to alternate pins in DDR mode. |
| SDIO/DCS, SCLK/DFS, CSB | SPI serial interface | Enables runtime configuration of data format, power-down, gain, and test patterns without external logic. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9230-250EBZ | 12-bit resolution, 250 MSPS max, same 56-lead LFCSP package and pinout as AD9211 family. | Higher ENOB (10.5 bits @ 70 MHz) but lower sample rate-suited for precision instrumentation over wideband capture. | Select when SNR > 65 dBFS and bandwidth < 125 MSPS suffices; requires no PCB change due to pin compatibility. |
| ADS54J60IRGC | Texas Instruments 14-bit, 500 MSPS ADC with JESD204B interface; 72-pin QFN, different pinout and power sequencing. | Supports serial high-speed interface to modern FPGAs but lacks on-chip reference and requires external clock conditioning. | Choose for JESD204B-based systems requiring >300 MSPS or higher resolution; redesign required for layout and power delivery. |
Compared with AD9230-250EBZ, the AD9211-300EBZ trades 2 bits of resolution for 20% higher sample rate and lower power (410 mW vs. ~650 mW), making it preferable for bandwidth-constrained radar and comms test. Versus ADS54J60IRGC, it offers simpler integration via parallel LVDS but lacks JESD204B scalability.

FAQ
What is the maximum sampling rate supported by the AD9211-300EBZ?
The AD9211-300EBZ supports a maximum conversion rate of 300 MSPS, as confirmed in Table 4 of the AD9211 Rev. 0 datasheet. This rate is guaranteed across the full industrial temperature range (−40°C to +85°C) with AVDD = DRVDD = 1.8 V and proper clock signal integrity. The AD9211-300EBZ evaluation board is configured to operate at this rated speed using its onboard clock synthesizer and LVDS output routing.
Does the AD9211-300EBZ require external reference components?
No, the AD9211-300EBZ does not require external reference components. As stated in the General Description and Features sections, it includes an on-chip reference and integrated input buffer and track-and-hold. The AD9211-300EBZ evaluation board leverages this feature-no external decoupling or reference buffers are needed, simplifying system design and reducing component count.
What output data formats does the AD9211-300EBZ support?
The AD9211-300EBZ supports three programmable output data formats: offset binary, twos complement, and Gray code-with offset binary as the default. These formats are selected via the SPI serial port interface (pins SDIO/DCS, SCLK/DFS, CSB), enabling runtime configuration without hardware modification. The AD9211-300EBZ evaluation board exposes these control lines for user-defined formatting.
How is the analog input range configured on the AD9211-300EBZ?
The analog input voltage range on the AD9211-300EBZ is programmable from 1.0 V to 1.5 V p-p differential via SPI register settings, with 1.25 V nominal. The CML pin provides a buffered common-mode reference (~1.4 V) for the VIN+/VIN− inputs. Configuration is performed through the AD9211-300EBZ evaluation software, which writes to the memory map locations defined in the datasheet's "AD9211 Configuration Using the SPI" section.
What is the power dissipation of the AD9211-300EBZ in LVDS DDR mode?
In LVDS DDR mode, the AD9211-300EBZ dissipates 410 mW at 300 MSPS, as specified in Table 1 (DC Specifications) of the Rev. 0 datasheet. This value includes contributions from both AVDD (analog) and DRVDD (digital output) supplies under full-scale −1 dBFS sine wave input conditions. The AD9211-300EBZ evaluation board monitors these rails to validate thermal performance during sustained operation.
