Analog Devices Inc. AD9637-80EBZ

Overview

AD9637-80EBZ from Analog Devices is an evaluation board for the AD9637 14-bit, 80 MSPS octal analog-to-digital converter, featuring on-board VFAC3HL-80MHZ clock oscillator, eight SMA analog input channels (J402–J704), and interface compatibility with the HSC-ADC-EVALCZ FPGA capture board for real-time data acquisition and FFT analysis in high-speed communications and instrumentation systems.

For engineers reviewing the AD9637-80EBZ datasheet, AD9637-80EBZ pinout, AD9637-80EBZ application, or AD9637-80EBZ equivalent, this page delivers verified hardware configuration details, clocking options, SPI control setup, VisualAnalog integration workflow, and channel-level signal routing guidance specific to the AD9637-80EBZ evaluation platform.

Technical Context

The AD9637-80EBZ implements a dedicated hardware interface between the AD9637 ADC and the HSC-ADC-EVALCZ FPGA capture board via a 160-pin Samtec QSH connector, supporting parallel CMOS output at 1.8 V logic levels and configurable SPI-based register access through onboard ADI firmware. It supports both internal 80 MHz crystal oscillator (VFAC3HL-80MHZ) and external clock injection via J802.

Signal conditioning includes eight 50 Ω single-ended SMA inputs with on-board anti-aliasing filter pads, jumper-selectable power modes (via J302/J804/J202), and FPGA I/O voltage setting (2.5 V via J9 on HSC-ADC-EVALCZ). The board requires dual 6 V/2 A supplies and USB 2.0 host connection for control and data streaming.

FAQ

What is the AD9637-80EBZ used for?

The AD9637-80EBZ is an evaluation board for the AD9637 octal ADC, enabling engineers to validate dynamic performance (SNR, SFDR), configure SPI registers, acquire real-time multi-channel data via VisualAnalog, and integrate the AD9637 into RF and instrumentation systems. It is not a standalone production component but a validated test platform for the AD9637 14-bit, 80 MSPS converter.

Does the AD9637-80EBZ include an on-board clock source?

Yes, the AD9637-80EBZ includes a VFAC3HL-80MHZ 80 MHz clock oscillator enabled by default via jumper J804 (XTAL_EN). This provides a low-jitter, factory-tuned timing reference for the AD9637. External clocking is supported via SMA connector J802 when J804 is removed.

Which software tools are required to operate the AD9637-80EBZ?

Operation of the AD9637-80EBZ requires Analog Devices' VisualAnalog for FFT and signal analysis, and SPIController for register-level configuration. The correct configuration file - AD9637_14Bit_80MSspiR03.cfg - must be loaded to match the AD9637-80EBZ's target device and sampling rate.

What power supplies does the AD9637-80EBZ require?

The AD9637-80EBZ requires two independent 6 V/2 A DC power supplies: one for the ADC evaluation board and another for the HSC-ADC-EVALCZ FPGA capture board. Both must be connected simultaneously for proper operation and noise isolation between analog and digital sections.

How are analog signals connected to the AD9637-80EBZ?

Analog signals are connected via eight SMA connectors labeled J402 (Ch. A), J403 (Ch. B), J502 (Ch. C), J503 (Ch. D), J601 (Ch. E), J604 (Ch. F), J701 (Ch. G), and J704 (Ch. H). Each accepts 50 Ω single-ended inputs; optimal performance requires low-phase-noise sources and optional band-pass filtering per channel.
