Analog Devices Inc. AD9642-210EBZ

Overview

AD9642-210EBZ from Analog Devices is a high-speed analog-to-digital converter evaluation board designed for the AD9642 14-bit, 210 MSPS dual-channel ADC. It supports USB 2.0 data capture via the HSC-ADC-EVALCZ FPGA-based capture board, features anti-aliasing filtering, and enables full characterization of SNR, SFDR, and ENOB at up to 210 MSPS under real-world clock and signal conditions.

For engineers reviewing the AD9642-210EBZ datasheet, AD9642-210EBZ pinout, AD9642-210EBZ application, or AD9642-210EBZ equivalent, this board provides validated signal chain integration with VisualAnalog and SPI Controller software, FPGA-configurable timing alignment (DCO delay/phase), and calibrated analog input path (J301) and clock input (J506) interfaces optimized for high-fidelity ADC testing.

Technical Context

The AD9642-210EBZ is a hardware platform built around the AD9642 IC and paired with the HSC-ADC-EVALCZ FPGA capture board. It implements a complete ADC test signal chain including 50 Ω RF input (J301), adjustable clock input (J506, 10–14 dBm), jumper-configurable I/O voltage (2.5 V on J9), and USB 2.0 host interface (J6).

It supports SPI-based register configuration of the AD9642 via the SPI Controller software using preloaded .cfg files (e.g., AD9642_14Bit_250MSspiR03.cfg), FPGA programming (AD9642_0.bin for XCPZ parts), and real-time FFT analysis in VisualAnalog with DCO timing alignment controls (600 ps delay, optional DCO clock inversion).

FAQ

What is the primary function of the AD9642-210EBZ?

The AD9642-210EBZ is an evaluation board specifically designed to characterize the AD9642 14-bit, 210 MSPS dual-channel ADC. It provides calibrated analog input (J301), clock input (J506), USB 2.0 data capture via the HSC-ADC-EVALCZ FPGA board, and full software integration with VisualAnalog and SPI Controller tools - enabling accurate measurement of dynamic performance parameters like SNR and SFDR for the AD9642.

Does the AD9642-210EBZ include the AD9642 IC?

Yes, the AD9642-210EBZ board integrates the AD9642-210EBZ target device - a 14-bit, 210 MSPS dual-channel analog-to-digital converter - as its core component. The board is not a generic platform; it is purpose-built for evaluating that specific IC variant, with matching layout, power delivery, and signal routing optimized for the AD9642's performance envelope.

What software is required to operate the AD9642-210EBZ?

Operation of the AD9642-210EBZ requires Analog Devices' VisualAnalog for FFT-based signal analysis and real-time data visualization, and the SPI Controller software for low-level register configuration of the AD9642. Both tools are freely available from analog.com/fifo and are preconfigured to recognize the AD9642-210EBZ and load appropriate FPGA bitstreams (e.g., AD9642_0.bin) and SPI configuration files (e.g., AD9642_14Bit_250MSspiR03.cfg).

How is clock timing aligned between the AD9642 and FPGA on the AD9642-210EBZ setup?

Timing alignment on the AD9642-210EBZ is achieved through configurable DCO (Delayed Clock Output) settings in the AD9642's registers. Users set a 600 ps additional delay on the DCO pin and optionally invert the DCO clock phase (for XCPZ-branded parts with date code ≠ 1126) via the SPI Controller software - ensuring synchronous sampling capture by the HSC-ADC-EVALCZ FPGA. This eliminates setup/hold violations and maximizes effective resolution.

Can the AD9642-210EBZ be used without the HSC-ADC-EVALCZ board?

No, the AD9642-210EBZ cannot perform data capture independently. It relies on the HSC-ADC-EVALCZ FPGA-based capture board for USB 2.0 interfacing, real-time data buffering, and clock domain translation. The AD9642-210EBZ provides only the ADC, analog front-end, and clock conditioning - all high-speed digital output signals (LVDS) are routed directly to the HSC-ADC-EVALCZ board; no standalone USB or processing capability exists on the AD9642-210EBZ itself.
