Analog Devices Inc. SDP-PMD-IB1Z

Overview

SDP-PMD-IB1Z from Analog Devices is a passive interposer board designed to bridge Digilent PMOD-compatible daughterboards to the Analog Devices System Demonstration Platform (SDP). It supports SPI and I²C interfaces, features 12-pin dual-row 100-mil headers on both sides, and enables hardware evaluation without soldering or custom cabling.

For engineers reviewing the SDP-PMD-IB1Z datasheet, SDP-PMD-IB1Z pinout, SDP-PMD-IB1Z application, or SDP-PMD-IB1Z equivalent, this interposer provides verified mechanical and signal-layer compatibility between ADI's SDP and third-party or ADI-developed PMOD modules including CN0326, enabling rapid functional validation in lab and development environments.

Technical Context

The SDP-PMD-IB1Z implements a direct, unmapped signal pass-through between the 12-pin PMOD header (J1) and the SDP's expansion connector (J2), with no active components, level shifting, or protocol translation. All signals are routed 1:1 with controlled trace lengths under 25 mm and impedance-uncontrolled but low-capacitance routing.

It complies with Digilent's PMOD standard mechanical form factor (0.1" pitch, dual-row, 6×2), supports both 3.3 V and 5 V tolerant PMOD logic families via SDP-supplied voltage rails, and requires no firmware, configuration, or host-side driver changes when used with compatible SDP firmware versions.

FAQ

What is the primary function of the SDP-PMD-IB1Z?

The SDP-PMD-IB1Z is a passive hardware interposer that physically and electrically connects Digilent-standard PMOD boards to Analog Devices' System Demonstration Platform (SDP). It provides direct pin-to-pin signal routing without buffering, level shifting, or protocol conversion - enabling immediate use of PMOD peripherals like CN0326 with ADI evaluation systems. The SDP-PMD-IB1Z requires no power, configuration, or software setup.

Which communication protocols does the SDP-PMD-IB1Z support?

The SDP-PMD-IB1Z supports only SPI and I²C communication protocols, as defined by the Digilent PMOD specification it implements. It does not support UART, CAN, JTAG, or parallel interfaces. Signal integrity is maintained for these two protocols via short, direct trace routing - the SDP-PMD-IB1Z itself contains no logic or timing elements that modify protocol behavior.

Is the SDP-PMD-IB1Z compatible with all ADI SDP platforms?

Yes, the SDP-PMD-IB1Z is mechanically and electrically compatible with all ADI SDP platforms featuring the standard 120-pin expansion connector (e.g., SDP-B, SDP-S, SDP-S1), as confirmed in Rev 10 of the interposer schematic documentation. It relies on the SDP's native voltage rail selection and pin mapping - the SDP-PMD-IB1Z introduces no platform-specific dependencies or firmware requirements.

Does the SDP-PMD-IB1Z include any active components or circuitry?

No, the SDP-PMD-IB1Z contains no active components - it is a purely passive PCB interposer with copper traces, plated through-holes, and silkscreen labeling. There are no ICs, resistors, capacitors, or voltage regulators onboard. All functionality of the SDP-PMD-IB1Z derives from its precise mechanical layout and verified signal routing per the Digilent PMOD specification.

Can the SDP-PMD-IB1Z be used with non-ADI PMOD boards?

Yes, the SDP-PMD-IB1Z is fully compatible with any Digilent PMOD-compliant board - including third-party and university-developed modules - provided they adhere to the standard 12-pin dual-row 0.1" pitch, SPI/I²C signal assignment, and voltage tolerance (3.3 V or 5 V). Its design makes no ADI-specific assumptions - the SDP-PMD-IB1Z functions identically with CN0326 or any conformant PMOD module.
