Analog Devices Inc. EVAL-AD7134FMCZ

Overview

EVAL-AD7134FMCZ from Analog Devices is a fully featured evaluation board for the AD7134 24-bit, 4-channel, simultaneous sampling, 1.5 MSPS precision alias-free analog-to-digital converter. It integrates two AD7134 ADCs on a single FMC-form-factor board, supports PC-based control via SDP-H1 interface, and enables multidevice synchronization testing in high-fidelity data acquisition systems such as precision instrumentation and audio test equipment.

For engineers reviewing the EVAL-AD7134FMCZ datasheet, EVAL-AD7134FMCZ pinout, EVAL-AD7134FMCZ application, or EVAL-AD7134FMCZ equivalent, this page provides verified hardware configuration options, clocking modes (crystal/MEMS/CMOS), power rail selection (8–14 V input → 5 V/1.8 V/1.2 V regulation), dual-ADC daisy-chaining capability, and software-controlled register access via AD7134 evaluation tool.

Technical Context

The EVAL-AD7134FMCZ implements a dual-AD7134 architecture with independent 4.096 V ADR444 references per device, configurable front-end input routing (direct/SMB/AMC), and flexible clock sourcing including crystal oscillator (Y1/Y2/Y3), MEMS clock, or SDP-H1-derived CLK. Power is supplied via the 160-pin FMC connector from the SDP-H1 board, with onboard dc-dc regulators generating 5 V, 1.8 V, and 1.2 V rails.

It supports both pin-control and SPI configuration modes via jumper-selectable resistors (R131/R132), offers eight differential analog inputs (Channels 0–7), and delivers time- and frequency-domain analysis through dedicated Waveform and Analysis tabs in the AD7134 evaluation software. DCLK is fixed at 48 MHz in all supported configurations.

FAQ

What is the primary function of the EVAL-AD7134FMCZ?

The EVAL-AD7134FMCZ is an evaluation board that enables functional validation, performance characterization, and system integration testing of the AD7134 24-bit, 4-channel, simultaneous sampling ADC. It provides hardware infrastructure-including dual ADCs, reference generation, power regulation, clock options, and FMC interface-to support rapid prototyping of precision data acquisition applications. The EVAL-AD7134FMCZ must be used with the SDP-H1 board and AD7134 evaluation software.

Which host interface does the EVAL-AD7134FMCZ require to operate?

The EVAL-AD7134FMCZ requires connection to the SDP-H1 system demonstration platform (EVAL-SDP-CH1Z) via its 160-pin VITA 57 FMC connector (P8). This interface supplies power, digital I/O lines (including DCLK and ODR), and SPI communication paths. No standalone operation is possible-the EVAL-AD7134FMCZ draws all operating power and control signals exclusively through the SDP-H1 link.

Does the EVAL-AD7134FMCZ support standalone (pin-controlled) operation without a PC?

Yes, the EVAL-AD7134FMCZ supports standalone operation in pin-control mode, configured via onboard jumpers (e.g., R132 mounted for PIN/SPI = Low). In this mode, hardware pins (MODE, CLKSEL, FILTER0/GPIO4, etc.) set conversion parameters, and status LEDs (DS1, DS2) indicate power presence. However, full data capture, visualization, and register-level control still require the AD7134 evaluation software running on a Windows PC connected via SDP-H1.

What clock sources are supported by the EVAL-AD7134FMCZ for the AD7134 devices?

The EVAL-AD7134FMCZ supports three clock source configurations: external crystal (Y1/Y2/Y3), MEMS oscillator (via R144/R145), or CMOS clock from SDP-H1 (via R230 closure). Each AD7134 can be independently configured using CLKSEL_1/CLKSEL_2 jumpers. Crystal option uses 20 MHz fundamental-mode crystals; MEMS option requires removal of Y2/Y3 and associated capacitors; SDP CLK option routes the SDP-H1's 48 MHz clock directly to XTAL2 pins.

Can the EVAL-AD7134FMCZ evaluate daisy-chained AD7134 configurations?

Yes, the EVAL-AD7134FMCZ supports daisy-chained operation using R580/R590 links to configure Device 1 as master (DCLK/ODR output) and Device 2 as slave (DCLK/ODR input). This enables synchronized sampling across both devices while reducing host interface pin count. The board's schematic and UG-1599 explicitly define jumper positions and signal routing for minimal I/O and daisy-chain modes, though the AD7134 evaluation software does not currently support daisy-chain configuration.
