Analog Devices Inc. AD9641-155KITZ

Overview

AD9641-155KITZ from Analog Devices is a full-featured evaluation board designed to characterize the AD9641 14-bit, 155 MSPS single-channel analog-to-digital converter (ADC) in real-world signal chain configurations. It supports JESD204A serial output (M=1, L=1, S=1, F=2, N'=16), external clock input up to 155 MHz, and dual power supply options (LDO or ADP2108 switching regulator). The board enables high-fidelity RF/IF sampling for communications and instrumentation applications.

For engineers reviewing the AD9641-155KITZ datasheet, AD9641-155KITZ pinout, AD9641-155KITZ application, or AD9641-155KITZ equivalent, key selection considerations include JESD204A lane configuration support, on-board clocking flexibility (external/LVPECL/VCXO), analog input drive options (balun-coupled or ADL5562 amplifier path), and FPGA-based data capture compatibility with FIFO-GX hardware.

Technical Context

The AD9641-155KITZ implements a complete signal chain for the AD9641 ADC, including transformer-coupled 50 Ω analog input with 2 V p-p full-scale range, configurable clock routing via T503 transformer or AD9524 PLL, and JESD204A-compliant digital output routed to P601 for FPGA capture. It supports both default LDO regulation and optional ADP2108 switching supply for AVDD/DRVDD.

Hardware configurability includes jumper-selectable power-down (P101), ADL5562 amplifier enable (P401), and clock source selection (P501 for Y502 oscillator). SPI-controlled register access enables real-time setup of sample rate, JESD204A parameters, and analog front-end biasing - all validated against the AD9641's specified AC performance at 155 MSPS.

FAQ

What is the primary function of the AD9641-155KITZ?

The AD9641-155KITZ is an evaluation board purpose-built to operate and characterize the AD9641 14-bit, 155 MSPS analog-to-digital converter. It provides all necessary support circuitry - including clock conditioning, analog input network, power regulation, and JESD204A output interface - enabling engineers to validate dynamic performance (SNR, SFDR), timing integrity, and system-level integration without custom PCB development. The AD9641-155KITZ is not a standalone IC or production component.

Does the AD9641-155KITZ support both single-ended and differential clock inputs?

No - the AD9641-155KITZ accepts only single-ended 50 Ω-terminated sine wave clock inputs by default (via J702), with typical drive level of 10–14 dBm. Differential clocking is supported indirectly through the AD9524 clock generator (U501), which outputs LVPECL signals to the AD9641's differential clock inputs. The board does not accept direct LVDS or CMOS clock inputs without modification or external level-shifting circuitry.

Can the AD9641-155KITZ be used with the AD9644 ADC?

No - the AD9641-155KITZ is physically and electrically configured exclusively for the single-channel AD9641. While it shares documentation (UG-294) and some layout conventions with AD9644 evaluation boards (e.g., AD9644-155KITZ), its analog input path, power routing, jumper settings (e.g., P401 for ADL5562 only), and FPGA configuration files (e.g., ad9644_41.rbf vs. AD9641-specific variants) are specific to the AD9641. Using it with the dual-channel AD9644 would require unsupported modifications and invalidates calibration data.

What FPGA capture hardware is required for the AD9641-155KITZ?

The AD9641-155KITZ requires the FIFO-GX FPGA-based data capture kit (sold separately) for JESD204A data acquisition. The board's P601 header routes serialized ADC output directly to the FIFO-GX, which implements the JESD204A receiver logic and buffers data for USB transfer to a host PC. VisualAnalog software loads precompiled .rbf configuration files (e.g., ad9644_41.rbf) onto the FIFO-GX FPGA - no HDL development is needed to begin evaluation of the AD9641-155KITZ.

Is the AD9641-155KITZ RoHS-compliant and lead-free?

Yes - the AD9641-155KITZ conforms to Analog Devices' standard RoHS-6 and lead-free manufacturing requirements, as documented in the AD9641 product family's official compliance statements and packaging specifications. All passive components, ICs (including AD9641, AD9524, ADP2108, ADL5562), and PCB fabrication on the AD9641-155KITZ meet JEDEC J-STD-609A Class 1 marking and IPC-J-STD-020 moisture sensitivity level (MSL) standards for lead-free assembly.
