Analog Devices Inc. AD9650-80EBZ

Overview

AD9650-80EBZ from Analog Devices is a dedicated evaluation board for the AD9650-80 16-bit, 80 MSPS dual-channel analog-to-digital converter (ADC), supporting full ac performance characterization with configurable clocking, input drive, and power options. It enables engineers to validate SNR (76.5 dBFS), SFDR (88.0 dBc), and ENOB (12.3 bits) under real-world signal chain conditions using VisualAnalog and SPI controller software.

For engineers reviewing the AD9650-80EBZ datasheet, AD9650-80EBZ pinout, AD9650-80EBZ application, or AD9650-80EBZ equivalent, this board provides validated test infrastructure for high-speed ADC system integration-including transformer-balun input paths, AD9517 clock synthesis support, LDO/switching power supply selection, and HSC-ADC-EVALCZ FPGA data capture compatibility.

Technical Context

The AD9650-80EBZ implements a dual-channel, 16-bit, 80 MSPS sampling architecture with differential CMOS outputs and supports both internal (1.35 V) and external reference configurations. Its default analog input network uses 15 Ω series resistors and 0.1 µF AC-coupling capacitors per channel, optimized for up to ~150 MHz input frequencies with 2 V p-p full-scale range.

Board-level clocking supports three modes: on-board Valpey Fisher VFAC3-BHL-80MHz oscillator (enabled via J605), external 50 Ω single-ended sine wave at J602, or AD9517-based LVPECL differential clocking (via U701 with R607/R608 populated). Power delivery includes selectable LDO regulation or ADP2114 switching regulators for AVDD/DRVDD rails.

FAQ

What is the primary function of the AD9650-80EBZ?

The AD9650-80EBZ is an evaluation board-not a semiconductor component-designed exclusively to characterize the AD9650-80 16-bit, 80 MSPS dual-channel ADC. It provides all necessary support circuitry including clock generation, analog input conditioning, power regulation, and FPGA-compatible digital output buffering. The AD9650-80EBZ enables measurement of key metrics like SNR, SFDR, and ENOB under controlled lab conditions using VisualAnalog and SPI Controller software.

Which ADC does the AD9650-80EBZ evaluate?

The AD9650-80EBZ evaluates only the AD9650-80: a 16-bit, dual-channel, 80 MSPS analog-to-digital converter with 76.5 dBFS SNR and 88.0 dBc SFDR. While the board's hardware shares layout with other families (e.g., AD9268, AD9269), its default configuration-including Figure 3 input network, J201 VREF jumper settings, and oscillator frequency-is specifically calibrated for the AD9650-80. The AD9650-80EBZ does not natively support or validate other ADC variants without hardware reconfiguration.

Does the AD9650-80EBZ include an on-board clock source?

Yes-the AD9650-80EBZ ships with an installed Valpey Fisher VFAC3-BHL-80MHz low-phase-noise oscillator (Y601) matched to the AD9650-80's rated speed. This oscillator is enabled by installing jumper J605 and populating C610 as a 0 Ω resistor. The AD9650-80EBZ also supports external clock injection at SMA connector J602 or AD9517-based LVPECL clock synthesis via U701 when configured per UG-003 Section 6.

What software tools are required to operate the AD9650-80EBZ?

The AD9650-80EBZ requires two proprietary Analog Devices software tools: VisualAnalog v1.0 for FFT-based performance analysis (including SNR, SFDR, and harmonic distortion plots) and the SPI Controller application for register-level configuration of the AD9650-80. Both tools interface via USB to the HSC-ADC-EVALCZ FPGA data capture board, which connects directly to the AD9650-80EBZ through P902/P903 headers. The AD9650-80EBZ does not function standalone without these tools.

Can the AD9650-80EBZ be powered using bench supplies instead of the included wall adapter?

Yes-the AD9650-80EBZ supports external bench power via P102 and P103 test points for independent biasing of analog (AVDD), digital (DVDD), and driver (DRVDD) domains. To use external supplies, ferrite beads E101, E102, E114, E103, E105, and E107 must be removed to isolate on-board LDOs. Required voltages are 1.8 V @ 1 A for AVDD/DRVDD, 1.8 V @ 1 A for DVDD, and optionally 3.3 V @ 1 A for clock circuitry. The AD9650-80EBZ retains full functionality under external power when configured per UG-003 Section 3.
