Analog Devices Inc. AD9233-80EBZ

Overview

AD9233-80EBZ from Analog Devices is an evaluation board for the AD9233BCPZ-80, a 12-bit, 80 MSPS analog-to-digital converter operating from a single 1.8 V analog supply with differential input bandwidth up to 650 MHz, SNR of 69.5 dBc at 70 MHz input, and SFDR of 85 dBc - designed for IF sampling in communications receivers and ultrasound equipment.

For engineers reviewing the AD9233-80EBZ datasheet, AD9233-80EBZ pinout, AD9233-80EBZ application, or AD9233-80EBZ equivalent, this page provides verified functional context, power and timing specifications, interface compatibility notes, and direct links to configuration resources for rapid prototyping of high-speed data acquisition systems.

Technical Context

The AD9233-80EBZ implements a multistage differential pipeline ADC architecture with on-chip sample-and-hold amplifier (SHA), internal voltage reference, and duty cycle stabilizer (DCS) for robust clock jitter tolerance. It supports offset binary, Gray code, or twos complement output formats and features a programmable serial port interface (SPI) for configuration of data alignment, DCS enable, and voltage reference mode.

It interfaces via LVDS/CMOS/LVPECL-compatible differential clock inputs (CLK+/CLK−), 12-bit parallel CMOS digital outputs (D0–D11), and auxiliary control signals including PDWN, OEB, OR, and DCO. The board supports flexible analog input drive configurations, default 2 V p-p differential input range, and 1.8 V to 3.3 V selectable digital output driver supply (DRVDD).

FAQ

What is the primary function of the AD9233-80EBZ?

The AD9233-80EBZ is an evaluation board for the AD9233BCPZ-80 analog-to-digital converter. Its primary function is to provide a fully tested, ready-to-use platform for evaluating the 12-bit, 80 MSPS ADC's performance-including SNR, SFDR, and timing behavior-under real-world analog input and clock conditions. The AD9233-80EBZ includes onboard clock conditioning, analog input transformers, and FPGA-compatible digital output headers to accelerate system-level validation.

Does the AD9233-80EBZ support multiple ADC speed grades?

No. The AD9233-80EBZ is specifically configured and calibrated for the AD9233BCPZ-80 variant, which is rated for 80 MSPS maximum sample rate. While the AD9233 family includes 105 MSPS and 125 MSPS versions (AD9233BCPZ-105/125), those require separate evaluation boards (AD9233-105EBZ and AD9233-125EBZ) due to differences in layout optimization, power delivery, and timing margining. The AD9233-80EBZ firmware and schematics are not interchangeable across speed grades.

What clock interface options does the AD9233-80EBZ support?

The AD9233-80EBZ supports differential clock inputs compatible with LVDS, LVPECL, and CMOS logic levels via its CLK+/CLK− terminals. It includes a duty cycle stabilizer (DCS) that maintains ADC performance across wide clock duty cycle variations (e.g., 30%–70%). The board accepts external clock sources through SMA connectors and also supports on-board crystal oscillator or clock generator options depending on jumper configuration - all validated for stable operation at 80 MSPS with <0.1 ps rms aperture jitter.

Can the AD9233-80EBZ be used with 3.3 V digital logic without level shifters?

Yes. The AD9233-80EBZ allows configuration of DRVDD between 1.8 V and 3.3 V, enabling direct connection to 3.3 V FPGA or ASIC I/O banks. When DRVDD is set to 3.3 V, the AD9233-80EBZ's D0–D11 outputs meet VOH ≥ 3.25 V and VOL ≤ 0.2 V under 0.5 mA/1.6 mA loads respectively - compliant with standard 3.3 V CMOS logic thresholds. No external level shifters are required if the host interface observes setup/hold timing margins per the AD9233-80EBZ timing diagram.

Is the AD9233-80EBZ pin-compatible with other Analog Devices evaluation boards?

No. The AD9233-80EBZ uses a custom 48-lead LFCSP footprint and proprietary interconnect layout optimized for the AD9233BCPZ-80's analog integrity and thermal performance. It is not mechanically or electrically pin-compatible with evaluation boards for other ADC families (e.g., AD9246, AD9628, or AD9467). However, it shares Analog Devices' standard EV-USB2EBZ interface and software stack (ACE software), enabling consistent configuration and data capture workflows across compatible evaluation platforms.
