Analog Devices Inc. AD9265-105EBZ

Overview

AD9265-105EBZ from Analog Devices is a high-speed analog-to-digital converter (ADC) evaluation board designed to fully characterize the AD9265-105 (16-bit, 105 MSPS) in bench and system-level applications. It supports differential analog input up to ~250 MHz, SPI-based configuration, and flexible clocking via on-board oscillator or AD9517-4 PLL, with CMOS output buffering for FPGA capture.

For engineers reviewing the AD9265-105EBZ datasheet, AD9265-105EBZ pinout, AD9265-105EBZ application, or AD9265-105EBZ equivalent, this board enables rapid ac performance validation-including SNR (76.5 dB), SFDR (88.0 dBc), and jitter-sensitive sampling-using VisualAnalog and SPIController software with HSC-ADC-EVALCZ data capture hardware.

Technical Context

The AD9265-105EBZ implements a complete signal chain for the AD9265BCPZ-105 ADC, including balun-coupled analog input path optimized for 50 Ω impedance and up to 250 MHz bandwidth, configurable VREF (1.0 V default), and RBIAS (10 kΩ) for core bias control. Clock options include a factory-installed low-phase-noise oscillator at 105 MHz or AD9517-4 LVPECL output routing.

Power architecture supports dual configurations: default LDO-regulated 1.8 V rails (AVDD, SVDD, DRVDD) or optional ADP2108 switching regulators for AVDD/DRVDD to evaluate efficiency trade-offs. Output signals are buffered through a 74VCX162827MTDX octal bus transceiver and routed via 60-pin header P2 to the HSC-ADC-EVALCZ FPGA platform.

FAQ

What is the primary function of the AD9265-105EBZ?

The AD9265-105EBZ is an evaluation board-not a standalone IC-that provides all necessary support circuitry, power regulation, clocking, analog input conditioning, and digital output interfacing to fully evaluate the AD9265BCPZ-105 16-bit, 105 MSPS analog-to-digital converter under real-world signal integrity and timing conditions.

Does the AD9265-105EBZ include the AD9265BCPZ-105 IC?

Yes, the AD9265-105EBZ ships populated with the AD9265BCPZ-105 as the device under test (DUT), as confirmed in the Bill of Materials (Item No. 17). The board is preconfigured for 105 MSPS operation, including matching clock source and reference settings.

Can the AD9265-105EBZ be used with other AD9265 speed grades?

No-the AD9265-105EBZ is specifically calibrated and configured for the AD9265BCPZ-105 variant. While the board's schematic accommodates multiple variants (per BOM Item 17 listing AD9265BCPZ-80/105/125), jumper, oscillator, and layout optimizations are fixed for 105 MSPS operation and must not be assumed compatible with 80 or 125 MSPS versions without revalidation.

What software tools are required to operate the AD9265-105EBZ?

Two primary tools are required: VisualAnalog for FFT-based ac performance analysis (SNR, SFDR, THD) and SPIController for register-level configuration of the AD9265BCPZ-105 via its serial interface. Both are freely available from analog.com/fifo and require Windows XP/Vista with USB 2.0 connectivity.

Is an external data capture board required for the AD9265-105EBZ?

Yes-the AD9265-105EBZ relies on the HSC-ADC-EVALCZ FPGA-based data capture kit (sold separately) to receive, buffer, and transfer the 16-bit parallel CMOS output stream (D0–D15, DCO, OR) from the AD9265BCPZ-105. The board's P2 header is mechanically and electrically designed exclusively for mating with the HSC-ADC-EVALCZ.
