Analog Devices Inc./Maxim Integrated MAX9602EUG+

Overview

MAX9602EUG+ from Maxim Integrated is a quad-channel, ultra-high-speed PECL-output comparator with 500ps propagation delay, 10ps channel-to-channel skew, and 30ps propagation delay dispersion-designed for high-fidelity pulse tracking in VLSI ATE, high-speed instrumentation, and logic analyzer front ends.

For engineers reviewing the MAX9602EUG+ datasheet, MAX9602EUG+ pinout, MAX9602EUG+ application, or MAX9602EUG+ equivalent, this page delivers verified electrical specs, real-world timing behavior (4Gbps toggle rate, 250ps minimum pulse width), PECL output drive capability (50Ω-terminated), and critical layout-aware design constraints for signal integrity at multi-Gbps speeds.

Technical Context

The MAX9602EUG+ implements a fully differential bipolar comparator core optimized for minimal propagation delay variation across input overdrive (100mV–2V), common-mode voltage (VEE + 3V to VCC − 2V), and temperature (−40°C to +85°C). Its open-emitter PECL outputs require external 50Ω pull-downs to VT = VCCO_ − 2V and are specified for direct 50Ω transmission-line driving.

Unlike the dual-channel MAX9600/MAX9601, the MAX9602EUG+ omits latch-enable (LE_, LE_) and hysteresis (HYS_) inputs-simplifying layout and reducing pin count for pure high-density comparison tasks. It operates from ±5.2V/+5V or ±4.2V/+6V supplies and delivers 4Gbps tracking frequency with <30ps delay dispersion under full-spec conditions.

Key Specifications

Pinout & Package

MAX9602EUG+ is housed in a 24-pin TSSOP package (4.4mm body width) with exposed pad for thermal enhancement. Pin numbering follows standard JEDEC TSSOP orientation (pin 1 top-left, counterclockwise).

Equivalent & Alternatives

The following parts are listed as comparable options for similar ultra-high-speed comparator applications.

Compared with MAX9601EUP+, the MAX9602EUG+ trades latch/hysteresis flexibility for higher channel density and simplified layout; compared with ADCMP572, it supports wider supply ranges and broader input common-mode voltage but consumes more current and requires negative rail management.

Availability

MAX9602EUG+ is available at Aetrix Electronics and suitable for VLSI ATE, high-speed instrumentation, and logic analyzer front-end designs requiring stable component supply, long-term lifecycle assurance, and guaranteed industrial-temperature operation.

Supply support for MAX9602EUG+ includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

Maxim Integrated (now part of Analog Devices) is a semiconductor company specializing in high-performance analog, mixed-signal, and RF solutions for industrial, communications, and computing markets.

The MAX9600/MAX9601/MAX9602 family was designed specifically for ultra-high-speed timing-critical applications-including automated test equipment and real-time instrumentation-where sub-nanosecond propagation delay and minimal skew are non-negotiable.

FAQ

What is the maximum data rate supported by the MAX9602EUG+?

The MAX9602EUG+ supports a 4Gbps tracking frequency, meaning it can reliably detect and output transitions on input signals toggling at up to 4 billion times per second. This is validated under AC conditions with 100mV input overdrive and 5pF load. The 500ps propagation delay and ≤30ps delay dispersion ensure accurate edge placement even at this rate. For sustained NRZ data, the practical limit aligns with 2GHz fundamental frequency due to rise/fall time constraints.

Does the MAX9602EUG+ include latch-enable or hysteresis functionality?

No, the MAX9602EUG+ does not include latch-enable (LE_, LE_) or hysteresis (HYS_) inputs. These features are present only in the MAX9600EUP+ and MAX9601EUP+ variants. The MAX9602EUG+ is optimized for pure high-speed comparison with four independent channels, omitting those controls to reduce complexity, improve speed consistency, and minimize pin count in the 24-pin TSSOP package.

What are the required termination conditions for the PECL outputs of the MAX9602EUG+?

The MAX9602EUG+ PECL outputs are open-emitter and require external 50Ω pull-down resistors connected to VT = VCCO_ − 2V. VCCO_ must be supplied separately (2.4V to VCC) and is typically set to 5V for standard PECL levels. Pull-downs must be placed close to the device pins to avoid stubs; mismatched or unterminated outputs cause reflections, timing jitter, and degraded VOH/VOL margins.

Can the MAX9602EUG+ operate from a single positive supply?

No, the MAX9602EUG+ requires both a positive supply (VCC, 4.3V–6.3V) and a negative supply (VEE, −6V to −4V) to bias its differential input stage and PECL output drivers. It is not compatible with single-supply operation. The specified input common-mode range (VEE + 3V to VCC − 2V) and output voltage swing depend on this dual-rail configuration. Attempting single-supply use will result in failure to meet propagation delay, offset, or output swing specifications.

How does propagation delay dispersion affect system-level timing in ATE applications?

Propagation delay dispersion in the MAX9602EUG+-defined as variation in tPD due to changes in input overdrive, slew rate, or common-mode voltage-directly impacts edge resolution in ATE pin electronics. With ≤30ps dispersion, the device maintains consistent timing across signal conditions, enabling accurate setup/hold window measurements and reducing calibration overhead. In contrast, comparators with >100ps dispersion introduce uncertainty that degrades test coverage at multi-Gbps rates.
