It integrates the AD9230-250 ADC with LVDS output, on-chip track-and-hold and reference, 700 MHz analog bandwidth, and 1.8 V dual-supply operation. The board supports real-time digitization of signals up to 170 MHz input frequency in wireless infrastructure and radar subsystems.

For engineers reviewing the AD9230-250EBZ datasheet, AD9230-250EBZ pinout, AD9230-250EBZ application, or AD9230-250EBZ equivalent, this page provides verified technical context, key specifications including SNR (64.1 dBFS @ 10.3 MHz), ENOB (10.5 bits), SFDR (−79 dBc @ 70 MHz), power dissipation (434 mW SDR mode), and functional pin mapping for system-level integration and FPGA interface design.

Technical Context

The AD9230-250EBZ implements a monolithic 12-bit pipeline ADC core with integrated track-and-hold and internal voltage reference, enabling direct connection to differential analog sources without external support circuitry. Its clock management includes duty cycle stabilizer and programmable data format (offset binary/twos complement/Gray code).

It operates with a differential LVDS clock input and delivers LVDS-compatible digital outputs at 250 MSPS in either SDR or DDR mode, with fixed 7-cycle latency and sub-0.3 ps RMS aperture jitter. The board routes all critical signals-including DCO±, CLK±, VIN±, and SPI control lines-to SMA connectors and headers for lab validation and prototype development.

FAQ

What is the primary function of the AD9230-250EBZ?

The AD9230-250EBZ is an evaluation board for the AD9230-250 12-bit, 250 MSPS analog-to-digital converter. It provides complete signal chain access-including analog input, clock, SPI configuration, and LVDS data outputs-enabling engineers to validate performance, interface with FPGAs, and develop firmware before system integration. The AD9230-250EBZ includes layout-optimized routing, decoupling, and SMA connectivity for lab-grade measurements.

Does the AD9230-250EBZ support both SDR and DDR LVDS output modes?

Yes, the AD9230-250EBZ supports both single-data-rate (SDR) and double-data-rate (DDR) LVDS output modes via SPI register configuration. In SDR mode, it delivers 12-bit parallel data at 250 MSPS with 434 mW total power; in DDR mode, it achieves equivalent throughput at 125 MHz clock rate with reduced power (400 mW) and relaxed timing margins. The AD9230-250EBZ board routes DCO± and all LVDS pairs to maintain signal integrity in either mode.

What analog input bandwidth does the AD9230-250EBZ support?

The AD9230-250EBZ supports a full-power analog input bandwidth of 700 MHz, as defined by the underlying AD9230-250 IC. This enables accurate digitization of wideband IF signals up to 170 MHz input frequency while maintaining ≥63.3 dBFS SNR and −78 dBc SFDR. The evaluation board's PCB layout preserves this bandwidth through controlled-impedance differential traces and optimized grounding for the VIN+/VIN− path.

How is the AD9230-250EBZ powered and what supply voltages are required?

The AD9230-250EBZ requires two 1.8 V supplies: AVDD for the analog section and DRVDD for the digital LVDS outputs. These are delivered via on-board LDO regulators from a single 3.3 V input or external bench supplies. The AD9230-250EBZ includes dedicated AVDD/DRVDD decoupling networks, ground plane segmentation, and thermal vias under the LFCSP package to ensure stable operation at 250 MSPS with <0.3 ps RMS jitter.

Can the AD9230-250EBZ be used with common FPGA development platforms?

Yes, the AD9230-250EBZ is designed for seamless interface with industry-standard FPGA platforms including Xilinx Kintex-7 and Intel Arria 10. Its LVDS outputs comply with ANSI-644 levels, and the DCO± clock output provides synchronous capture timing. The AD9230-250EBZ includes pin-compatible headers and documented I/O voltage mapping to simplify HDL integration, timing closure, and JESD204B-ready signal conditioning.
