Analog Devices Inc./Maxim Integrated MAX9600EUP

Overview

The MAX9600EUP from Maxim Integrated is a dual-channel ultra-high-speed ECL-output comparator with 500ps propagation delay, 10ps channel skew, and -2.2V to +3V input common-mode range under ±5.2V/5V supplies. It features latch-enable (LE_, LE_) and current-controlled hysteresis (HYS_) for track-hold/sampling operation and noise immunity in high-fidelity pulse tracking applications such as VLSI ATE and logic analyzer front ends.

For engineers reviewing the MAX9600EUP datasheet, MAX9600EUP pinout, MAX9600EUP application, or MAX9600EUP equivalent, this page delivers verified electrical parameters, validated 20-pin TSSOP package mapping, confirmed ECL output drive capability into 50Ω loads, and real-world timing constraints including 250ps minimum pulse width and 250ps latch setup time - all critical for high-speed signal integrity design.

Technical Context

The MAX9600EUP implements a bipolar differential-input stage optimized for sub-nanosecond timing fidelity, with propagation delay dispersion held below 30ps across input overdrive (100mV–2V), slew rate (0.2–10V/ns), and common-mode voltage (VEE+3V to VCC−2V). Its complementary ECL outputs require external 50Ω pull-down resistors to VT = −2V and deliver VOH = −0.94V / VOL = −1.72V (TA = +25°C) with 4Gbps toggle capability.

Latch enable operates differentially: LE_ low / LE_ high enables compare mode; LE_ high / LE_ low forces latched output state. Hysteresis is set via RHYS_ (10kΩ–35kΩ to GND), yielding 5–60mV input-referred hysteresis. Input bias current remains ≤20µA across −40°C to +85°C, supporting stable DC-coupled high-speed threshold detection.

FAQ

What is the maximum operating frequency supported by the MAX9600EUP?

The MAX9600EUP supports a 4Gbps tracking frequency toggle rate with 550mVP-P output swing and 100mV input overdrive. This is validated across −40°C to +85°C and corresponds to reliable operation at 2GHz fundamental frequency in square-wave applications. The 500ps propagation delay and <30ps delay dispersion ensure consistent timing behavior at these rates. MAX9600EUP performance remains stable under specified supply and termination conditions.

How do I configure hysteresis on the MAX9600EUP?

Hysteresis on the MAX9600EUP is configured by connecting a single external resistor (RHYS_) from the HYS_ pin to GND. Values between 10kΩ and 35kΩ yield 5–60mV of input-referred hysteresis, as shown in the HYSTERESIS vs. RHYS graph. For zero hysteresis, leave HYS_ open or tie it to VCC. The MAX9600EUP datasheet specifies RHYS_ tolerance impact on hysteresis accuracy and confirms operation across temperature.

What are the correct termination requirements for MAX9600EUP ECL outputs?

The MAX9600EUP ECL outputs require 50Ω pull-down resistors (RL) connected from each output (QA, QA, QB, QB) to VT = −2V. Resistors must be 50Ω–75Ω, placed close to the device. This termination establishes proper VOH (−0.94V) and VOL (−1.72V) levels and ensures impedance-matched driving of 50Ω transmission lines. Incorrect VT or RL values degrade timing fidelity and increase jitter in the MAX9600EUP output waveform.

Can the MAX9600EUP operate with non-standard supply voltages?

Yes - the MAX9600EUP is specified for VCC = 4.3–6.3V and VEE = −6 to −4V, supporting both standard −5.2V/+5V and shifted −4.2V/+6V rails. Input common-mode range adjusts accordingly: −1.2V to +4V with +6V/−4.2V supplies. All AC/DC specifications, including 500ps propagation delay and 10ps skew, are guaranteed across this full supply range and −40°C to +85°C.

What is the function of the complementary latch-enable pins (LE_, LE_) on the MAX9600EUP?

The MAX9600EUP uses differential latch-enable inputs: LE_ low / LE_ high enables compare (track) mode; LE_ high / LE_ low forces latch mode, freezing outputs at their last valid state. This permits precise sampling windows without external logic. The inputs accept standard ECL logic levels, with defined setup (250ps) and hold (300ps) times relative to the latch edge. Unused latch enables must be terminated to valid ECL states to prevent metastability in the MAX9600EUP.
