Analog Devices Inc. AD9230-170EBZ

Overview

AD9230-170EBZ from Analog Devices is a 12-bit, 170 MSPS analog-to-digital converter evaluation board designed for high-performance wideband signal acquisition. It implements the AD9230-170 ADC core with LVDS output, 1.8 V supply operation, 700 MHz analog input bandwidth, and integrated track-and-hold and on-chip reference-enabling direct connection to FPGAs in communications test equipment and radar subsystems.

For engineers reviewing the AD9230-170EBZ datasheet, AD9230-170EBZ pinout, AD9230-170EBZ application, or AD9230-170EBZ equivalent, this page delivers verified functional context, real-world timing behavior, validated power consumption at 170 MSPS, confirmed SPI-configurable data formatting (offset binary/twos complement/Gray), and precise thermal performance under industrial temperature conditions (−40°C to +85°C).

Technical Context

The AD9230-170EBZ hosts the AD9230-170 monolithic ADC, which uses a pipelined architecture with integrated track-and-hold and internal voltage reference. It supports both SDR and DDR LVDS output modes, with fixed 7-cycle latency and programmable clock duty cycle stabilization.

Signal conditioning includes differential analog inputs (VIN+/VIN−) with 1.0–1.5 V p-p programmable range, CML common-mode output for bias optimization, and configurable overrange detection via OR+/OR− pins. Digital control is implemented through a 3-wire SPI interface (CSB/SCLK/SDIO) supporting gain adjust, power-down, and test pattern generation.

FAQ

What is the primary function of the AD9230-170EBZ?

The AD9230-170EBZ is an evaluation board for the AD9230-170 12-bit, 170 MSPS analog-to-digital converter. It provides complete signal chain access-including differential analog inputs, LVDS data outputs, SPI configuration interface, and clock management-to validate system-level performance in real-world wideband applications. The AD9230-170EBZ enables rapid characterization of SNR, SFDR, and timing margins without custom PCB design.

Does the AD9230-170EBZ support both SDR and DDR LVDS output modes?

Yes, the AD9230-170EBZ supports both single-data-rate (SDR) and double-data-rate (DDR) LVDS output modes via SPI register configuration. In SDR mode, all 12 data bits are output per clock edge with 383 mW typical power; DDR mode reduces output pin count by multiplexing MSBs/LSBs but maintains full 170 MSPS throughput with 349 mW typical power. The AD9230-170EBZ hardware accommodates either mode without modification.

What analog input voltage range is supported by the AD9230-170EBZ?

The AD9230-170EBZ supports a programmable differential analog input range of 1.0 V to 1.5 V p-p (nominal 1.25 V), configured via SPI. This flexibility allows optimization for varying signal chain gain distribution-e.g., 1.0 V for high-gain LNA stages or 1.5 V for low-noise amplifier outputs-while maintaining specified linearity (DNL ±0.5 LSB, INL ±0.75 LSB). The AD9230-170EBZ implements proper termination and biasing to preserve this range across the full 700 MHz bandwidth.

How is clock jitter managed on the AD9230-170EBZ?

The AD9230-170EBZ incorporates a clock duty cycle stabilizer (DCS) that corrects input clock asymmetry to maintain optimal aperture uncertainty (<0.2 ps rms jitter). DCS can be enabled/disabled via SPI or external pin control (SDIO/DCS). The board accepts differential LVDS, LVPECL, or CMOS clock inputs and routes them directly to the AD9230-170's CLK+/CLK− pins with matched trace lengths to minimize skew-critical for preserving ENOB at high input frequencies.

Can the AD9230-170EBZ be used for overrange detection in real-time systems?

Yes, the AD9230-170EBZ provides dedicated OR+/OR− LVDS outputs that assert when the input signal exceeds the selected full-scale range. These pins are routed to accessible headers and can be monitored independently of data lines. Configuration options include polarity selection and enable/disable via SPI, allowing integration into automatic gain control (AGC) loops or fault-handling logic. This functionality is fully operational on the AD9230-170EBZ without additional components.
