Analog Devices Inc./Maxim Integrated MAX19516EVKIT#

Overview

MAX19516EVKIT# from Maxim Integrated is a fully assembled and tested evaluation kit designed to characterize the MAX19516 - a 10-bit, 100 Msps dual-channel analog-to-digital converter (ADC) in 48-pin TQFN package. It supports single-ended analog input conversion to differential signals via on-board transformers (T1–T4), provides programmable CMOS digital outputs with DCLK/DORA timing control, and operates from a single 3.6V nominal supply with on-board regulation for AVDD and OVDD.

For engineers reviewing the MAX19516EVKIT# datasheet, MAX19516EVKIT# pinout, MAX19516EVKIT# application, or MAX19516EVKIT# equivalent, this kit enables rapid validation of high-speed ADC performance in RF sampling, communications infrastructure, and test instrumentation - with Windows 7/10 GUI software, SPI interface, adjustable clock duty cycle, and user-selectable supply voltages (1.8V/2.5V/3.0V/3.3V).

Technical Context

The MAX19516EVKIT# implements a four-layer PCB layout with separate analog, digital, clock, and buffer power planes to minimize noise coupling. It uses 100Ω differential microstrip lines for analog and clock inputs (matched within ±0.002"), and 50Ω microstrip lines for all 10-bit parallel digital outputs routed to header J5.

On-board circuitry includes dual MAX8902A LDOs (U14/U15) for independent AVDD and OVDD/VLOGIC regulation, an FT232-based USB-to-SPI bridge (U3), dual 16-bit buffers (U11/U12), and transformer-based single-ended-to-differential conversion (T1–T4) supporting 1MHz–400MHz input bandwidth.

FAQ

What is the primary function of the MAX19516EVKIT#?

The MAX19516EVKIT# is a ready-to-use evaluation platform for the MAX19516ETM+ 10-bit, 100 Msps dual-channel ADC. It provides full signal chain support - including single-ended-to-differential conversion, regulated power delivery, programmable output timing, and Windows-based GUI control - enabling immediate performance validation without custom board design. The MAX19516EVKIT# eliminates prototyping delays for RF sampling and communications applications.

Which ADC does the MAX19516EVKIT# evaluate?

The MAX19516EVKIT# evaluates the MAX19516ETM+, a 10-bit, dual-channel, 100 Msps analog-to-digital converter housed in a 48-pin TQFN-EP package. It is part of the MAX19505–MAX19507/MAX19515–MAX19517 family and shares hardware compatibility across resolution/speed variants - but the MAX19516EVKIT# is specifically configured and calibrated for the MAX19516ETM+ device.

Does the MAX19516EVKIT# support both differential and single-ended clock inputs?

Yes, the MAX19516EVKIT# supports both configurations. In differential mode, the clock is applied directly to CLK± SMA connectors. In single-ended mode, the clock signal passes through buffer U10 and is shaped using potentiometer R46 for adjustable duty cycle - verified by measurement at test point TP3 (USB3V3). Configuration requires resistor rework per the EV kit documentation.

How is digital output data accessed from the MAX19516EVKIT#?

Digital output data from the MAX19516EVKIT# is available at the 48-pin header J5, which exposes all 10-bit parallel outputs per channel (D0A–D9A, D0B–D9B), plus DCLKA/B and DORA/B signals. These are buffered by U11 and U12 (SN74AUC16244DGGR) to drive logic analyzers or FPGA interfaces. Pin mapping matches the MAX19516ETM+ datasheet and is documented in the schematic (Sheet 1 of 5).

What software is required to operate the MAX19516EVKIT#?

The MAX19516EVKIT# requires the MAX195xx Dual ADC EV Kit Software (MAX195xxGUI.exe), distributed by Maxim Integrated. It runs on Windows 7/10, communicates via USB Mini-B (J6), and provides real-time control over output format (two's complement/offset binary/gray), timing alignment, power states, clock synchronization (slip/edge mode), and input common-mode settings - all targeting the MAX19516ETM+ registers.
