Analog Devices Inc./Maxim Integrated MAX1198EVKIT

Overview

MAX1198EVKIT from Maxim Integrated is an evaluation kit for the MAX1198 - a dual, 8-bit, 100Msps analog-to-digital converter optimized for imaging, instrumentation, and digital communications. It supports fully differential or single-ended inputs, features on-chip 2.048V reference, parallel CMOS-compatible outputs, and operates from 2.7V–3.6V analog supply with 264mW typical power at full speed.

For engineers reviewing the MAX1198EVKIT datasheet, MAX1198EVKIT pinout, MAX1198EVKIT application, or MAX1198EVKIT equivalent, this kit enables rapid validation of high-speed dual-channel sampling performance-including SINAD (48.1dB @ 50MHz), interchannel crosstalk (–72dB), gain/phase matching (±0.05dB / ±0.1°), and flexible reference configuration (internal/buffered/unbuffered external).

Technical Context

The MAX1198EVKIT implements a complete test platform for the MAX1198 ADC, featuring calibrated clock distribution, differential input signal conditioning, configurable reference routing (REFIN/REFOUT/REFP/REFN), and level-shifted parallel digital output buffers compatible with 1.7V–3.6V logic families. It supports both TQFP-48 socketed operation and direct PCB mounting.

It provides access to all critical control signals-CLK, OE, PD, SLEEP, and T/B-and includes onboard decoupling (0.1µF + 2.2µF per supply rail), impedance-matched SMA input paths, and jumper-selectable power domains (VDD/OVDD/GND/OGND) to isolate analog/digital noise during characterization of dynamic performance metrics like SFDR (66dBc @ 50MHz) and THD (–64dBc).

FAQ

What is the primary function of the MAX1198EVKIT?

The MAX1198EVKIT is an evaluation kit designed specifically to characterize and validate the performance of the MAX1198 dual 8-bit 100Msps ADC. It provides signal conditioning, clock distribution, reference configuration options, and interface circuitry enabling engineers to measure key dynamic parameters-including SINAD, SFDR, interchannel crosstalk, and gain/phase matching-under controlled lab conditions before integration into final systems.

Does the MAX1198EVKIT support both differential and single-ended analog inputs?

Yes, the MAX1198EVKIT supports both fully differential and single-ended analog input configurations for the MAX1198. Its SMA input paths are impedance-matched and include onboard termination options and common-mode biasing networks to ensure optimal signal integrity for either mode, aligning with the MAX1198's specified ±1VP-P differential or single-ended input voltage range and COM pin functionality.

Can the MAX1198EVKIT be used to evaluate external reference configurations?

Yes, the MAX1198EVKIT supports all three reference modes of the MAX1198: internal (via REFOUT→REFIN), buffered external (voltage applied to REFIN), and unbuffered external (REFIN grounded). Jumper-selectable connections and dedicated test points for REFP, REFN, COM, and REFIN allow precise setup and measurement of reference-dependent performance such as offset error (±4%FS) and gain temperature coefficient (±100ppm/°C).

What digital interface standards does the MAX1198EVKIT accommodate?

The MAX1198EVKIT accommodates CMOS-compatible digital interfacing through its dual 8-bit parallel output buses (D7A–D0A and D7B–D0B), each with active-low OE control. It supports OVDD supply voltages from 1.7V to 3.6V, enabling direct connection to FPGA I/O banks, microcontroller parallel ports, or logic analyzers without level-shifting-matching the MAX1198's specified VOH (OVDD – 0.2V) and VOL (0.2V) thresholds.

Is the MAX1198EVKIT compatible with other devices in the MAX119x family?

The MAX1198EVKIT is mechanically and electrically optimized for the MAX1198 (100Msps), but its layout and signal routing also support evaluation of pin-compatible variants including the MAX1197 (60Msps) and MAX1195 (40Msps), as well as the multiplexed-output MAX1196. However, full-speed dynamic testing beyond 100Msps requires verification of clock path integrity and timing margins specific to each device's maximum fCLK rating.
