Product details
Overview
MAX9692EUB+T from Maxim Integrated is a single-channel, ultra-fast ECL-output comparator with latch-enable functionality, designed for high-speed signal conditioning in RF and digital test systems. It delivers 1.2ns typical propagation delay, 100ps skew, and operates from +5V/-5.2V supplies to drive 50Ω-terminated transmission lines at >600MHz bandwidth. Its open-emitter outputs require external pull-down resistors (50Ω–200Ω to –2.0V or 240Ω–2000Ω to –5.2V) and support sample-hold operation via the LE input.
For engineers reviewing the MAX9692EUB+T datasheet, MAX9692EUB+T pinout, MAX9692EUB+T application, or MAX9692EUB+T equivalent, key selection criteria include latch-enable timing (0.5ns setup/hold), ECL-level compatibility, differential input matching (±11.5mV offset), temperature-stable propagation delay (2.0ns max over –40°C to +85°C), and µMAX-10 package constraints for high-density PCB layouts.
Technical Context
The MAX9692EUB+T implements a BiCMOS-based ECL comparator core with fully differential inputs and complementary open-emitter outputs. Its latch-enable circuitry enables precise edge-triggered sampling, with LE logic thresholds defined at –1.1V (high) and –1.5V (low), and supports clean acquisition of fast transient signals when input slew rate exceeds 1V/µs.
It features dual ground pins (GND1 for input stage bias, GND2 for output stage bias), requiring connection to a solid copper ground plane. Layout mandates microstrip routing, local 0.01µF ceramic decoupling at VCC/VEE pins, and controlled-impedance termination to maintain signal integrity above 600MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 1.2ns typical (2.0ns max); enables sub-500ps timing resolution in high-speed trigger circuits. |
| Propagation Delay Skew | 100ps max; ensures matched Q/Q̅ transitions critical for clock/data recovery and differential signaling. |
| Latch Setup/Hold Time | 0.5ns each; supports precise sampling of <1ns-wide pulses without metastability. |
| Input Offset Voltage | ±11.5mV max over temperature; maintains DC accuracy in threshold detection across –40°C to +85°C. |
| Supply Voltages | +5V (VCC) and –5.2V (VEE); standard ECL-compatible dual-rail supply for interoperability with legacy ECL logic families. |
| Output Drive | Open-emitter outputs capable of sinking ≥50mA; compatible with 50Ω–200Ω pull-down to –2.0V or –5.2V for impedance-matched transmission line driving. |
| Common-Mode Range | –2.5V to +3.0V; accommodates wide-swing differential inputs while rejecting common-mode noise up to 80dB. |
Pinout & Package
The MAX9692EUB+T is housed in a 10-pin µMAX® package (outline 21-0061, land pattern 90-0330), RoHS-compliant, with 0.5mm pitch and exposed pad for thermal enhancement. Pin 1 is marked with dot; device requires ground-plane layout and tight decoupling.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND1 | Input-stage ground reference; must connect to solid ground plane to stabilize biasing of differential pair. |
| 2 | GND2 | Output-stage ground reference; separate from GND1 to isolate ECL output switching noise from input circuitry. |
| 3 | Q OUT | Complementary ECL output; open-emitter requiring external pull-down resistor to –2.0V or –5.2V. |
| 4 | Q OUT | ECL output; complements Pin 3; both outputs swing between –1.06V (high) and –1.89V (low) into 50Ω load. |
| 5 | N.C. | No internal connection; must remain unconnected per datasheet. |
| 6 | IN− | Inverting input terminal; differential pair input with 60kΩ input resistance and 3pF capacitance. |
| 7 | IN+ | Non-inverting input terminal; matched to IN− for <100ps skew and low dispersion. |
| 8 | VCC | +5V positive supply; requires 0.01µF ceramic capacitor placed adjacent to pin for high-frequency decoupling. |
| 9 | VEE | –5.2V negative supply; same decoupling requirement as VCC; defines ECL logic voltage levels. |
| 10 | LE | Latch-enable input; ECL-compatible control pin (–1.5V low / –1.1V high); drives sample-hold mode when pulled low. |
Key Features

Applications
| High-Speed Line Receivers | Peak Detectors |
|---|---|
Use Scenario: Recovering data from high-speed serial links with jitter-sensitive clock recovery. IC Role / Device Role / Timing Role: Comparator acts as decision circuit in CDR loop, comparing incoming signal against threshold and generating retimed ECL logic edges. Use Value: 1.2ns propagation delay and 100ps skew minimize timing uncertainty, enabling reliable sampling at 600+ MHz data rates. | Use Scenario: Capturing amplitude peaks in pulsed RF waveforms for radar or spectrum analysis. IC Role / Device Role / Timing Role: Comparator monitors envelope-detected signal and triggers latch on peak crossing; LE input freezes output at extremum. Use Value: 0.5ns latch setup time ensures accurate capture of <1ns-wide RF pulses without droop or overshoot artifacts. |
| Threshold Detectors | High-Speed Triggers |
Use Scenario: Detecting voltage excursions beyond safety or alarm thresholds in power monitoring or sensor interfaces. IC Role / Device Role / Timing Role: Compares sensed analog voltage against reference; outputs ECL-level alert signal with minimal latency.

Use Value: Sub-nanosecond timing parameters (tpd, ts, th) eliminate trigger jitter, improving measurement repeatability below 1ps RMS. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ECL-output comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX9692ESE+ | 16-pin SO package; identical electrical specs but larger footprint and higher thermal resistance (7.4mW/°C derating vs. 8.8mW/°C for µMAX). | Suitable for prototyping or lower-frequency designs where board space permits larger package and thermal management is less constrained. | Select MAX9692ESE+ when SO package compatibility, hand-soldering feasibility, or legacy footprint reuse is required. |
| MAX9693EEE+ | Dual-channel QSOP-16 variant; shares same propagation delay (1.2ns), latch timing, and supply specs but adds second independent comparator channel. | Used in applications requiring two synchronized comparators (e.g., window detectors, differential receivers with redundancy). | Choose MAX9693EEE+ only when dual-channel functionality justifies added cost and board area; not a drop-in replacement for single-channel use. |
Compared with MAX9692EUB+T, MAX9692ESE+ trades compactness for manufacturability and thermal margin, while MAX9693EEE+ adds channel count at the expense of pin compatibility and increased complexity-neither offers pin-to-pin equivalence, so PCB redesign is required for either alternative.

FAQ
What is the maximum operating frequency supported by the MAX9692EUB+T?
The MAX9692EUB+T supports signal processing at frequencies exceeding 600MHz, as confirmed by its 1.2ns typical propagation delay and verified in application circuits with 100MHz–1GHz input signals. This capability stems from its BiCMOS architecture and optimized ECL output stage, enabling clean edge transitions in high-speed line receivers and triggers.
How should the LE (latch-enable) pin be configured if not used in the MAX9692EUB+T design?
If the latch-enable function is unused in the MAX9692EUB+T, the LE pin must be connected to ground (VEE = –5.2V reference), per datasheet guidance. Leaving it floating risks undefined output states and potential oscillation due to ECL input sensitivity. No pull-up or biasing to intermediate voltages is permitted.
What are the recommended external pull-down resistor values for the MAX9692EUB+T outputs?
The MAX9692EUB+T open-emitter outputs require external pull-down resistors: 50Ω–200Ω connected to –2.0V, or 240Ω–2000Ω connected to –5.2V. Values within these ranges ensure proper ECL logic levels (VOH ≈ –1.06V, VOL ≈ –1.89V) and 50Ω transmission line matching for minimal reflections.
Does the MAX9692EUB+T require separate ground connections for input and output stages?
Yes, the MAX9692EUB+T has two dedicated ground pins: GND1 (Pin 1) for the input differential pair and GND2 (Pin 2) for the ECL output stage. Both must connect to a low-inductance solid copper ground plane, but they serve distinct bias domains-mixing them without proper plane partitioning degrades skew and noise rejection.
What is the guaranteed propagation delay specification for the MAX9692EUB+T over temperature?
The MAX9692EUB+T guarantees a maximum propagation delay of 2.0ns over the full operating temperature range of –40°C to +85°C, with 1.2ns typical at +25°C. This spec is validated under standard conditions (VCC = +5V, VEE = –5.2V, RL = 50Ω to VT = –2V) and reflects worst-case performance across process, voltage, and temperature corners.
