Analog Devices Inc./Maxim Integrated MAX19515EVKIT#

Overview

MAX19515EVKIT# from Maxim Integrated is a fully assembled and tested evaluation kit designed to characterize the MAX19515ETM+ - a 10-bit, 65 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 MAX19515EVKIT# datasheet, MAX19515EVKIT# pinout, MAX19515EVKIT# application, or MAX19515EVKIT# equivalent, this kit enables rapid validation of high-speed ADC performance in RF receiver chains, communications test equipment, and digitizer modules - with Windows 7/10 GUI software, SPI interface, and logic analyzer-ready J5 header output.

Technical Context

The MAX19515EVKIT# implements a complete signal chain for the MAX19515 ADC family: it accepts single-ended analog inputs (1 MHz–400 MHz), converts them to differential signals using four ADT1-1WT+ transformers, and delivers buffered 10-bit parallel CMOS outputs (D0A–D9A, D0B–D9B) plus DCLKA/B and DORA/B bits at J5. Clocking supports both differential and single-ended modes, with on-board clock-shaping circuitry and adjustable duty cycle via potentiometer R46.

Power management is implemented via two MAX8902A LDOs (U14/U15), each pin-selectable for 1.8V/2.5V/3.0V/3.3V output, configured through jumpers J1/J8/J9/J10. Programming is supported via SPI (enabled by jumper JU7 open) or parallel mode (JU7 shunted), with register updates executed through the included MAX195xxGUI.exe software.

FAQ

What is the primary function of the MAX19515EVKIT#?

The MAX19515EVKIT# is an evaluation kit that enables full characterization of the MAX19515ETM+ 10-bit, 65 Msps dual-channel ADC. It provides all necessary signal conditioning, power regulation, SPI programming interface, and Windows-based GUI software to evaluate AC performance, timing behavior, and power management features without custom hardware design.

Which ADC models does the MAX19515EVKIT# support?

The MAX19515EVKIT# is specifically designed for the MAX19515ETM+, but shares hardware compatibility across the MAX19515–MAX19517 family. It supports the 10-bit variants: MAX19515ETM+ (65 Msps), MAX19516ETM+ (100 Msps), and MAX19517ETM+ (130 Msps), all in 48-pin TQFN packages - verified by identical PCB layout, transformer network, and power architecture.

How is analog input handled on the MAX19515EVKIT#?

The MAX19515EVKIT# accepts single-ended analog signals via SMA connectors (VINA/VINB) and converts them to differential signals using four ADT1-1WT+ transformers (T1–T4). This eliminates the need for external baluns and ensures optimal common-mode rejection and dynamic performance up to 400 MHz, as confirmed in the schematic and Bill of Materials.

What software tools are included with the MAX19515EVKIT#?

The MAX19515EVKIT# includes the MAX195xxDualADCEVKit SoftwareInstaller.exe, which deploys MAX195xxGUI.exe - a Windows 7/10 application providing real-time control over output format (two's complement/offset binary/gray code), input common-mode voltage, clock divider, sync mode, power management states, and output timing adjustments via SPI communication with the onboard ADC.

Can the MAX19515EVKIT# operate from a standard USB port?

No - the MAX19515EVKIT# requires an external 3.6V nominal DC power supply (2.1V–5V range) connected to the VSUPPLY banana jack. While it connects to a host PC via USB Mini-B (J6) for SPI communication and GUI control, the USB port does not provide sufficient current for board operation; the 3.6V supply powers all analog, digital, and clock circuitry including the MAX8902A regulators.
