Analog Devices Inc./Maxim Integrated MAX19505EVKIT#

Overview

MAX19505EVKIT# from Maxim Integrated is a fully assembled and tested evaluation kit designed to characterize the MAX19505–MAX19507/MAX19515–MAX19517 family of 8-bit and 10-bit, dual-channel, high-speed analog-to-digital converters (ADCs) operating up to 130 Msps. It supports single-ended analog input conversion to differential signals via on-board transformers (T1–T4), provides USB-based SPI control via FT232RL-compatible interface (U3), and delivers regulated 1.8V/2.5V/3.0V/3.3V analog (AVDD) and digital (OVDD/VLOGIC) supplies using dual MAX8902A LDOs (U14/U15).

For engineers reviewing the MAX19505EVKIT# datasheet, MAX19505EVKIT# pinout, MAX19505EVKIT# application, or MAX19505EVKIT# equivalent, this kit enables rapid validation of ADC dynamic performance (SNR, SFDR), timing margining, power management modes (standby, A+B adder), output format configuration (two's complement, offset binary, gray code), and clock synchronization (slip/edge mode) in RF receiver, communications test equipment, and high-speed data acquisition systems.

Technical Context

The MAX19505EVKIT# implements a four-layer PCB layout with separate analog, digital, clock, and buffer power planes to minimize noise coupling. It uses 100Ω matched-length differential microstrip traces for analog and clock inputs and 50Ω microstrip lines for all digital outputs (J5 header), ensuring signal integrity at frequencies up to 400 MHz.

Hardware programmability is supported via jumpers JU1–JU3 (parallel mode) and JU6/JU7 (SHDN/SPEN control), while full register-level configuration is enabled through Windows 7/10-compatible GUI software communicating over USB Mini-B (J6) using FTDI-based MPSSE protocol. On-board clock-shaping circuitry (R46 + U10) allows adjustable duty cycle tuning for single-ended clock operation.

FAQ

What is the primary function of the MAX19505EVKIT#?

The MAX19505EVKIT# is a fully assembled evaluation kit that enables engineers to validate the performance of the MAX19505–MAX19507/MAX19515–MAX19517 family of dual-channel, high-speed ADCs. It provides signal conditioning (single-ended to differential conversion), regulated power distribution, USB-based SPI control, and parallel digital output access - all on a noise-optimized four-layer PCB. The MAX19505EVKIT# itself contains no ADC; it hosts the target device (e.g., MAX19505ETM+) in its U1 socket.

Which ADC models are compatible with the MAX19505EVKIT#?

The MAX19505EVKIT# supports six specific ADC variants: MAX19505ETM+, MAX19506ETM+, MAX19507ETM+, MAX19515ETM+, MAX19516ETM+, and MAX19517ETM+. All share the same 48-pin TQFN-EP package and pinout, differing only in resolution (8-bit vs. 10-bit) and sampling speed (65/100/130 Msps). The kit's hardware and software are preconfigured to recognize and configure each variant automatically upon selection in the GUI.

How does the MAX19505EVKIT# handle analog input signal conditioning?

The MAX19505EVKIT# accepts single-ended analog inputs via SMA connectors (VINA/VINB) and converts them to differential signals using four miniature broadband transformers (T1–T4, ADT1-1WT+), supporting input frequencies from 1 MHz to 400 MHz. This eliminates the need for external baluns during evaluation. Input common-mode voltage is software-adjustable per channel (CHA/CHB Adjust), and self-bias options are available via the GUI.

What power supply requirements does the MAX19505EVKIT# have?

The MAX19505EVKIT# operates from a single 3.6V nominal DC supply (VSUPPLY), with an absolute maximum rating of 5V. On-board MAX8902A LDO regulators (U14/U15) generate user-selectable analog (AVDD) and digital (OVDD/VLOGIC) voltages - 1.8V, 2.5V, 3.0V, or 3.3V - via jumper configurations (J1/J8/J9/J10). Minimum input voltage depends on selected output voltage and is specified in the kit's documentation (e.g., 2.1V for 1.8V AVDD).

Can the MAX19505EVKIT# be used without a Windows PC?

No - the MAX19505EVKIT# requires a Windows 7 or Windows 10 PC with two spare USB ports to run the official MAX195xx EV Kit software (MAX195xxGUI.exe), which communicates with the board via USB Mini-B (J6) using FTDI-based MPSSE protocol. The GUI provides essential register-level control over output format, timing, clock sync, and power modes. No Linux/macOS drivers or standalone firmware are provided by Maxim for the MAX19505EVKIT#.
