Analog Devices Inc. AD6643-200EBZ

Overview

AD6643-200EBZ from Analog Devices is a high-speed dual-channel 11-bit analog-to-digital converter evaluation board designed for the AD6643-200EBZ IC, supporting 200 MSPS sampling rate per channel, JESD204B serial interface, and DC–900 MHz input bandwidth. It enables RF receiver testing in communications infrastructure and radar systems.

For engineers reviewing the AD6643-200EBZ datasheet, AD6643-200EBZ pinout, AD6643-200EBZ application, or AD6643-200EBZ equivalent, this board supports FPGA-based data capture via HSC-ADC-EVALCZ, VisualAnalog FFT analysis, SPI configuration (AD6643spiR03.cfg), DCO timing alignment, and dual-channel coherent sampling validation.

Technical Context

The AD6643-200EBZ evaluation board interfaces directly with the AD6643 ADC IC, which features two 11-bit 200 MSPS channels, JESD204B subclass 0/1 output, on-chip dither, and programmable digital gain control. It requires external 2.5 V FPGA I/O voltage (set via J9 jumper) and clean analog clock input at J506 (10–14 dBm, low jitter).

Signal acquisition uses shielded 50 Ω coaxial cabling to J301/J303, supports narrow-band band-pass filtering (e.g., TTE, Allen Avionics), and relies on VisualAnalog for real-time FFT analysis and SPIController for register-level configuration including FLEXOUTPUT DELAY(17) DCO delay tuning.

FAQ

What is the AD6643-200EBZ used for?

The AD6643-200EBZ is an evaluation board for the AD6643 dual-channel 11-bit 200 MSPS ADC. It enables system-level verification of JESD204B data capture, timing alignment, and dynamic performance in RF receivers. Engineers use AD6643-200EBZ with HSC-ADC-EVALCZ and VisualAnalog to validate real-world signal integrity and spectral purity before integration into base stations or radar front ends.

Does the AD6643-200EBZ include the AD6643 IC?

Yes, the AD6643-200EBZ evaluation board integrates the AD6643-200EBZ target device - a fully populated, factory-tested AD6643 dual-channel 11-bit 200 MSPS ADC. The board provides all necessary power regulation, clock conditioning, and JESD204B routing to support immediate functional evaluation without additional component assembly.

What software tools are required to operate the AD6643-200EBZ?

Operation of the AD6643-200EBZ requires VisualAnalog for FFT-based performance analysis and SPIController for register configuration using AD6643spiR03.cfg. Both tools are provided by Analog Devices and support FPGA programming of the HSC-ADC-EVALCZ capture board, DCO delay tuning, and real-time data streaming from the AD6643-200EBZ ADC core.

How is clock timing aligned on the AD6643-200EBZ?

Timing alignment on the AD6643-200EBZ is achieved by configuring the FLEXOUTPUT DELAY(17) register in the AD6643 IC via SPIController to apply 600 ps additional delay on the DCO output pin. This compensates for PCB trace skew between the AD6643-200EBZ and HSC-ADC-EVALCZ, ensuring synchronous sampling capture in VisualAnalog.

Can the AD6643-200EBZ be used for single-tone and multi-tone testing?

Yes, the AD6643-200EBZ supports both single-tone and multi-tone testing through its dual-channel architecture and configurable input path. With proper band-pass filtering and calibrated signal generator levels (8–12 dBm at J301/J303), engineers can characterize SFDR, SNR, and ENOB across frequency bands up to 900 MHz using the AD6643-200EBZ in conjunction with VisualAnalog's FFT engine.
