Product details
Overview
MAX9602EUG+T from Maxim Integrated is a quad-channel, ultra-high-speed PECL-output comparator with 500ps propagation delay, 10ps channel-to-channel skew, and 4Gbps tracking frequency. It operates from ±5.2V/+5V supplies, accepts differential inputs from (VEE + 3V) to (VCC − 2V), and drives 50Ω-terminated transmission lines directly - ideal for high-density ATE front ends and logic analyzer trigger paths.
For engineers reviewing the MAX9602EUG+T datasheet, MAX9602EUG+T pinout, MAX9602EUG+T application, or MAX9602EUG+T equivalent, this page delivers verified electrical specs, PECL output interface details, TSSOP-24 package mapping, and validated alternative comparators for high-speed pulse tracking and low-timing-dispersion systems.
Technical Context
The MAX9602EUG+T implements a fully differential bipolar comparator core optimized for minimal propagation delay dispersion (<30ps typical) 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 referenced to VCCO_, not GND.
Unlike the dual-channel MAX9600/MAX9601, the MAX9602EUG+T omits latch-enable (LE_, LE_) and hysteresis (HYS_) pins - it is a pure high-speed compare-only device with four independent channels in a single 24-pin TSSOP package.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation delay | 500ps typical - enables sub-nanosecond timing resolution in pulse-width measurement and edge detection. |
| Propagation delay skew | 10ps max - ensures tight channel-to-channel alignment critical for multi-lane signal capture. |
| Tracking frequency | 4Gbps - supports direct comparison of NRZ data streams up to 2GHz fundamental frequency. |
| Input common-mode range | VEE + 3V to VCC − 2V - accommodates wide-swing signals with ±5.2V/5V supplies (e.g., −2.2V to +3V). |
| Output type | Differential PECL - requires external 50Ω pull-downs to VT = VCCO_ − 2V; VOH/VOL swing referenced to VCCO_. |
| Supply range | VCC = 4.3V to 6.3V, VEE = −6V to −4V, VCCO_ = 2.4V to VCC - supports flexible logic-level interfacing. |
| Operating temperature | −40°C to +85°C - qualified for industrial-grade ATE and instrumentation environments. |
Pinout & Package
The MAX9602EUG+T is housed in a 24-pin TSSOP package (4.4mm body width) with exposed pad for thermal enhancement. All pins are surface-mount, gull-wing leaded, and RoHS-compliant.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2 | INA+, INA− | Channel A differential analog input pair - high-impedance (100MΩ), 2pF capacitance, supports rail-to-rail common-mode swing. |
| 3, 9 | VEE | Negative supply rail - must be connected to −4V to −6V; shared across all four channels. |
| 4, 5 | INB+, INB− | Channel B differential analog input pair - electrically identical to Channel A; no crosstalk degradation up to 4Gbps. |
| 6, 12 | VCC | Positive supply rail - 4.3V to 6.3V; powers internal comparator core and bias circuitry. |
| 7, 8 | INC+, INC− | Channel C differential analog input - independently buffered; matched delay vs. Channels A/B/D within 40ps. |
| 10, 11 | IND+, IND− | Channel D differential analog input - full 4-channel operation supported without performance derating. |
| 13, 14 | QD, QD | Channel D complementary PECL outputs - open-emitter; require 50Ω pull-down to VT = VCCO_ − 2V. |
| 15 | VCCOD | Channel D output driver positive supply - sets PECL logic reference; 2.4V ≤ VCCOD ≤ VCC. |
| 16, 17 | QC, QC | Channel C complementary PECL outputs - identical drive strength and timing to QD/QD. |
| 18 | VCCOC | Channel C output driver supply - independent of VCCOD; allows per-channel logic level tuning. |
| 19, 20 | QB, QB | Channel B complementary PECL outputs - guaranteed 10ps skew vs. QA/QA under matched layout. |
| 21 | VCCOB | Channel B output driver supply - decoupled from VCCOA to minimize inter-channel supply noise coupling. |
| 22, 23 | QA, QA | Channel A complementary PECL outputs - primary timing reference channel; lowest jitter (300fs RMS at 50MHz). |
| 24 | VCCOA | Channel A output driver supply - must be stable; ripple < 10mV p-p to maintain VOH/VOL accuracy. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low propagation delay | 500ps typ - enables time-of-flight measurements with <0.5ns uncertainty in test equipment. |
| Low propagation delay dispersion | <30ps over 100mV–2V overdrive - maintains consistent timing across varying signal amplitudes in ATE pin electronics. |
| Quad-channel integration | Four independent comparators in one 24-pin TSSOP - reduces board area by >40% vs. two dual-channel packages. |
| PECL-compatible outputs | Open-emitter outputs with VCCO_-referenced swing - interoperable with standard 50Ω PECL receivers without level-shifting. |
| High CMRR & PSRR | 70dB CMRR, 65dB PSRR - rejects noise from shared supply rails and adjacent high-speed traces in dense PCB layouts. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-high-speed comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX9601EUP+ | Dual-channel PECL comparator with latch-enable and hysteresis; 20-pin TSSOP; same 500ps delay and 4Gbps tracking. | Supports track-hold/sampling modes; suited for gated measurement systems where latching is required. | Select MAX9601EUP+ when latch control or adjustable hysteresis is needed; MAX9602EUG+T is preferred for pure parallel compare tasks. |
| ADCMP572BCPZ-R7 | Single-channel 2.5Gbps ECL comparator; 16-pin LFCSP; 650ps delay; includes internal 50Ω termination. | Limited to one channel; lacks quad integration; uses ECL (not PECL) outputs referenced to GND. | Choose ADCMP572BCPZ-R7 for space-constrained single-channel designs requiring integrated termination and lower power (24mA vs. 39mA). |
Compared with MAX9601EUP+, the MAX9602EUG+T trades latch/hysteresis capability for 2× channel density in the same footprint-class package; versus ADCMP572BCPZ-R7, it delivers 1.6× higher speed, 4× channel count, and PECL compatibility at the cost of external termination and higher supply current.

FAQ
What is the maximum data rate supported by the MAX9602EUG+T?
The MAX9602EUG+T supports a 4Gbps tracking frequency, meaning it can reliably compare NRZ data streams with toggle rates up to 2GHz. This is validated under AC conditions with 100mV input overdrive and 5pF load, and reflects its ability to resolve edges with <500ps propagation delay and <30ps dispersion - making MAX9602EUG+T suitable for high-speed ATE pin electronics and real-time logic analysis.
Does the MAX9602EUG+T include latch-enable or hysteresis functionality?
No, the MAX9602EUG+T does not include latch-enable (LE_, LE_) or hysteresis (HYS_) pins. Unlike the MAX9600/MAX9601 variants, the MAX9602EUG+T is a dedicated quad-channel compare-only device. Its pinout omits those controls to maximize channel density and minimize propagation path complexity - confirming MAX9602EUG+T's role in continuous, high-fidelity pulse tracking rather than sampled or noise-immune operation.
What are the required external components for proper operation of the MAX9602EUG+T?
The MAX9602EUG+T requires external 50Ω pull-down resistors from each Q_/Q output to VT = VCCO_ − 2V, plus 0.01µF ceramic decoupling capacitors placed adjacent to each VCC, VEE, and VCCOx pin. No hysteresis resistor is needed (HYS pins absent), and no latch-control logic is required - simplifying layout versus latch-capable variants while preserving MAX9602EUG+T's ultra-fast response.
How does the MAX9602EUG+T differ from the MAX9600EUP+ in output interface?
MAX9602EUG+T provides differential PECL outputs referenced to VCCO_, requiring pull-downs to VT = VCCO_ − 2V, whereas MAX9600EUP+ delivers ECL outputs referenced to GND with pull-downs to −2V. This makes MAX9602EUG+T compatible with PECL-based FPGA I/O banks and clock receivers, while MAX9600EUP+ interfaces directly with legacy ECL logic - a key distinction in system-level signal chain design involving MAX9602EUG+T.
Is the MAX9602EUG+T pin-compatible with other devices in the MAX9600 family?
No, the MAX9602EUG+T is not pin-compatible with MAX9600EUP+ or MAX9601EUP+. It uses a 24-pin TSSOP package with unique pin assignments - including four independent VCCOx supplies (VCCOA–VCCOD) and no LE_/HYS pins - whereas the dual-channel variants use 20-pin TSSOP with shared latch/hysteresis controls. This physical and functional divergence confirms MAX9602EUG+T as a purpose-built quad solution, not a drop-in upgrade.
