Product details
Overview
The MAX9600EUP+ from Maxim Integrated is a dual-channel ultra-high-speed ECL-output comparator with 500ps propagation delay, 10ps channel-to-channel skew, and -2.2V to +3V input common-mode range under ±5.2V/5V supplies - designed for high-fidelity pulse tracking in VLSI ATE and logic analyzer front ends.
For engineers reviewing the MAX9600EUP+ datasheet, MAX9600EUP+ pinout, MAX9600EUP+ application, or MAX9600EUP+ equivalent, key selection criteria include ECL-compatible differential output drive into 50Ω, latch-enable control for track/hold operation, adjustable hysteresis via external resistor, and guaranteed -40°C to +85°C operation in 20-pin TSSOP.
Technical Context
The MAX9600EUP+ employs a bipolar process with 558 transistors to achieve sub-nanosecond timing precision. Its differential input stage supports wide common-mode range (VEE + 3V to VCC – 2V) and delivers complementary ECL outputs requiring external 50Ω pull-downs to VT = –2V.
It integrates dual independent comparators, each with dedicated latch-enable (LE_, LE_) and hysteresis (HYS_) inputs. Latch enable permits synchronous sampling with 250ps setup time and 300ps hold time; hysteresis is current-controlled via RHYS_ (10kΩ–35kΩ to GND), yielding 5–60mV input-referred hysteresis.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 500ps typical - enables 4Gbps signal tracking with minimal timing uncertainty. |
| Propagation Delay Skew | 10ps max - ensures matched timing between Channel A and B for synchronized decision-making. |
| Input Common-Mode Range | –2.2V to +3V with ±5.2V/5V supplies - accommodates wide-swing analog inputs without level-shifting. |
| Output Type | Differential ECL - drives 50Ω transmission lines directly with VOH = –0.94V, VOL = –1.72V (TA = +25°C). |
| Latch Enable Inputs | Differential ECL-compatible (–2V to 0V swing) - supports track-hold/sample-hold modes with 250ps setup time. |
| Hysteresis Control | Current-controlled via RHYS_ to GND (10kΩ–35kΩ) - provides 5–60mV adjustable noise immunity. |
| Supply Range | VCC = 4.3V to 6.3V, VEE = –6V to –4V - supports standard –5.2V/+5V or shifted –4.2V/+6V rails. |
Pinout & Package
MAX9600EUP+ is housed in a 20-pin TSSOP package (4.4mm body width) with exposed pad for thermal enhancement. Pin 1 is QA (Channel A output); pin 2 is QA (complementary); pins 6 and 15 are VEE; pins 7 and 14 are VCC; pins 4 and 17 are LEA/LEB (latch-enable); pins 8 and 13 are HYSA/HYSB; inputs INA+/INA– occupy pins 10/9; INB+/INB– occupy pins 11/12.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2 | QA, QA | Channel A differential ECL output pair - requires 50Ω pull-down to VT = –2V for valid logic levels. |
| 4, 5 | LEA, LEA | Channel A latch-enable differential input - driven by ECL logic; low/high pair selects track vs. latch mode. |
| 8 | HYSA | Channel A hysteresis current control - connects to GND via RHYS_ (10kΩ–35kΩ) to set noise margin. |
| 9, 10 | INA–, INA+ | Channel A differential input - accepts signals from (VEE + 3V) to (VCC – 2V) with 70dB CMRR. |
| 11, 12 | INB+, INB– | Channel B differential input - electrically identical to Channel A; independent operation supported. |
| 13 | HYSB | Channel B hysteresis current control - independently configurable from HYSA for asymmetric noise rejection. |
| 16, 17 | LEB, LEB | Channel B latch-enable differential input - fully independent of Channel A for asynchronous sampling. |
| 19, 20 | QB, QB | Channel B differential ECL output pair - identical drive capability and termination requirements as QA/QA. |
| 6, 15 | VEE | Negative supply rail - must be connected to common –5.2V (or –4.2V) source with low-inductance decoupling. |
| 7, 14 | VCC | Positive supply rail - must be connected to common +5V (or +6V) source with 0.01µF ceramic decoupling. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low propagation delay | 500ps typical - enables precise edge detection in 4Gbps serial data recovery paths. |
| Matched dual-channel timing | 10ps max skew - preserves phase alignment between parallel signal paths in ATE pin electronics. |
| Configurable hysteresis | 5–60mV input-referred via single RHYS_ resistor - eliminates false triggering on noisy low-slew inputs. |
| Synchronous latch capability | 250ps setup / 300ps hold time - supports deterministic sampling at multi-GHz rates with external clock. |
| Wide-supply operational flexibility | Supports both –5.2V/+5V and –4.2V/+6V rails - simplifies integration into legacy ECL and modern mixed-voltage systems. |

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 output (not ECL); VCCO_ required for output driver; latch enable compatible with PECL logic. | Used where system-level signaling is PECL-based (e.g., telecom line cards), not ECL; same pinout but different termination (to VCCO_ – 2V). | Select MAX9601EUP+ when interfacing to PECL receivers or when VCCO_ biasing simplifies board-level supply architecture. |
| ADCMP572BCPZ-R7 | Single-channel, 2.5V/3.3V CMOS output; 300ps propagation delay; no latch enable or hysteresis inputs. | Targeted at low-voltage, single-ended digital systems (e.g., FPGA I/O conditioning); lacks dual-channel correlation and sampling control. | Choose ADCMP572BCPZ-R7 only for cost-sensitive, single-channel, non-latched applications with 3.3V logic compatibility. |
Compared with MAX9601EUP+, the MAX9600EUP+ offers native ECL-level outputs eliminating level translation; versus ADCMP572BCPZ-R7, it provides dual-channel synchronization, latch control, and hysteresis - essential for ATE and instrumentation-grade timing integrity.

FAQ
What is the recommended termination for MAX9600EUP+ ECL outputs?
The MAX9600EUP+ ECL outputs require external 50Ω pull-down resistors connected to VT = –2V. This establishes valid VOH (–0.94V) and VOL (–1.72V) levels per channel. Using 50Ω–75Ω resistors within this range ensures proper static and dynamic operation while maintaining impedance matching for high-speed transmission lines. Do not leave outputs unterminated or connect to GND.
Can MAX9600EUP+ operate with supply voltages other than –5.2V/+5V?
Yes, the MAX9600EUP+ supports alternative supply configurations including –4.2V/+6V, verified in the Absolute Maximum Ratings and DC Electrical Characteristics tables. At –4.2V/+6V, the input common-mode range shifts to –1.2V to +4V, and output swing remains compliant with ECL logic thresholds. Ensure VCC – VEE stays within 9.5V–11.5V for guaranteed performance.
How is hysteresis configured on MAX9600EUP+?
Hysteresis on the MAX9600EUP+ is set by connecting an external resistor (RHYS_) from HYSA or HYSB to GND. Values from 10kΩ to 35kΩ yield 60mV to 5mV input-referred hysteresis. For zero hysteresis, leave HYS_ open or tie to VCC. The hysteresis current flows from the internal 2.5V source at HYS_, making RHYS_ the sole determinant of noise margin.
What is the function of the dual latch-enable inputs (LE_, LE_) on MAX9600EUP+?
The complementary LE_, LE_ inputs on MAX9600EUP+ control track-hold behavior: when LE_ is low and LE_ is high, the comparator tracks input changes; when LE_ is high and LE_ is low, outputs latch to their last state. This enables synchronous sampling. Invalid states (both high or both low) result in undefined outputs - always drive them differentially with ECL logic.
Does MAX9600EUP+ support operation at –40°C to +85°C without derating?
Yes, the MAX9600EUP+ is fully specified and production-tested over –40°C to +85°C. All key parameters - including 500ps propagation delay, 10ps skew, and ECL output voltage levels - are guaranteed across this range. No derating is required for thermal performance; the 20-pin TSSOP package dissipates up to 879mW at +70°C with standard derating above that point.
