Analog Devices Inc./Maxim Integrated MAX104EVKIT

Overview

MAX104EVKIT from Maxim Integrated is a fully assembled, four-layer evaluation board designed to characterize the dynamic performance of the MAX104 1 Gsps ultra-high-speed analog-to-digital converter (ADC), including on-board PECL/ECL termination voltage generation (PECLVTT and ECLVTT), ±250 mV analog input range, SMA-connected clock/analog inputs, and demultiplexed differential PECL outputs for logic analyzer interfacing.

For engineers reviewing the MAX104EVKIT datasheet, MAX104EVKIT pinout, MAX104EVKIT application, or MAX104EVKIT equivalent, this page delivers verified layout details, power supply requirements (+5 V analog/digital, –5 V analog, +3.3 V output), jumper-configurable demux modes (DIV1/DIV2/DIV4), offset adjustment via R2 potentiometer, and precise microstrip routing for jitter-sensitive high-speed ADC evaluation.

Technical Context

The MAX104EVKIT implements a dedicated high-speed PCB architecture using GETek™ laminate (ε_r = 3.9) with 50 Ω microstrip transmission lines-18-mil width over 10-mil core-for analog inputs (J1/J2), clock inputs (J3/J4), and PECL outputs, minimizing signal integrity degradation up to 1 GHz sampling.

It integrates on-board bias generation for ECL (–2 V ECLVTT via LM2991 regulator from VEE) and PECL (PECLVTT = VCCO – 2 V) termination, supports single-ended or differential analog/clock drive, and provides configurable demultiplexing (via jumpers JU6–JU9) for primary/auxiliary 8-bit PECL output ports (P0–P7, A0–A7) plus DREADY+/– and OR+/– signals.

FAQ

What is the primary function of the MAX104EVKIT?

The MAX104EVKIT is a fully assembled evaluation board designed to enable accurate dynamic performance testing of the MAX104 1 Gsps analog-to-digital converter. It provides all necessary circuitry-including SMA-connected analog/clock inputs, on-board PECL/ECL termination voltage generation, demultiplexed differential PECL outputs, and configurable jumpers-for lab-based ADC characterization without custom PCB design.

Does the MAX104EVKIT support other ADCs besides the MAX104?

Yes-the MAX104EVKIT is mechanically and electrically compatible with the MAX106 (600 Msps) and MAX108 (1.5 Gsps) as well. All three devices share the same 192-contact ESBGA package and pinout, and the board's power, clock, analog, and digital interfaces are designed to accommodate the full family per Maxim's documentation.

How is the PECL termination voltage (PECLVTT) generated on the MAX104EVKIT?

PECLVTT on the MAX104EVKIT is derived from the VCCO supply as VCCO – 2 V and is used to bias the external 50 Ω termination resistors for the differential PECL outputs. This voltage is generated on-board and does not require an external source; it scales with the selected VCCO (between +3.0 V and +5.0 V).

What jumper settings are required to operate the MAX104EVKIT in DIV2 demultiplexed mode?

To activate DIV2 mode on the MAX104EVKIT, install jumpers JU7 (DEMUXEN), JU8 (AUXEN2), and JU9 (AUXEN1) in the ON position, and set jumper JU6 (DIVSELECT) to position 2. The board ships from the factory with these exact settings preconfigured for immediate use.

Can the MAX104EVKIT be used with a logic analyzer that only accepts single-ended inputs?

Yes-the MAX104EVKIT's differential PECL outputs (P0+/P0–, A0+/A0–, etc.) are terminated on-board with 50 Ω resistors to PECLVTT, and each pair connects to a 0.100-inch square 2-pin header. Users can connect single-ended logic analyzer pods to either the "+" or "–" side of each output pair, as confirmed in Maxim's Quick Start guide and Figure 1/2 schematics.
