Product details
Overview
MAX9375EUA+T from Maxim Integrated is a fully differential, single-channel LVDS/anything-to-LVPECL translator optimized for high-speed signal integrity in backplane and network routing systems. It supports up to 2GHz switching frequency, delivers 421ps typical propagation delay, maintains ≤30ps pulse skew, operates from +3.3V supply, and accepts differential inputs as low as 100mV across LVDS/LVPECL/HSTL/CML standards.
For engineers reviewing the MAX9375EUA+T datasheet, MAX9375EUA+T pinout, MAX9375EUA+T application, or MAX9375EUA+T equivalent, key selection criteria include guaranteed 2GHz operation, sub-500ps propagation delay, LVPECL output drive into 50Ω, temperature-compensated output levels, and ESD robustness exceeding 2kV HBM.
Technical Context
The MAX9375EUA+T implements a bipolar-based differential translator architecture with emitter-follower LVPECL outputs requiring termination to VCC − 2.0V. Its input stage features rail-to-rail common-mode range (0.05V to VCC − 0.05V) and 100mV minimum differential threshold, enabling interoperability across multiple signaling standards without level-shifting circuitry.
AC performance is characterized with 125ps (20%–80%) input transition time and validated up to 1.34GHz input frequency; jitter is specified at ≤2psRMS, and propagation delay variation over −40°C to +85°C remains within ±30ps of typical 421ps.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switching Frequency | 2.0GHz min - supports OC-48/STM-16 and 10GbE physical layer timing paths |
| Propagation Delay | 421ps typ - enables sub-nanosecond timing alignment in multi-lane serial interconnects |
| Pulse Skew | 30ps max - ensures matched rising/falling edge timing critical for differential clock distribution |
| Differential Output Swing | 595–725mV - provides sufficient margin for LVPECL receiver thresholds under process/voltage/temp variation |
| Supply Voltage Range | +3.0V to +3.6V - compatible with standard 3.3V logic rails and tolerant of ±10% regulation error |
| ESD Protection | ≥2kV HBM - meets IEC 61000-4-2 Level 2 for board-level handling and system integration |
| Input Sensitivity | 100mV min differential - guarantees reliable switching with low-amplitude CML or degraded LVDS signals |
Pinout & Package
The MAX9375EUA+T is housed in an 8-pin µMAX package (3.05mm × 3.05mm × 0.8mm), thermally enhanced with exposed pad (not electrically connected), and requires dual ceramic bypassing (0.1µF + 0.01µF) on VCC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8 | VCC | Positive supply input - must be bypassed locally to GND; powers internal bias and output stages |
| 2 | IN | Noninverting differential input - accepts LVDS, CML, HSTL, or generic differential signals |
| 3 | IN | Inverting differential input - forms full differential pair with Pin 2; defines input common-mode window |
| 4, 5 | GND | Power ground reference - low-inductance return path essential for noise immunity and jitter control |
| 6 | OUT | Inverting LVPECL output - requires 50Ω termination to VCC − 2.0V for proper DC bias and fast edge rates |
| 7 | OUT | Noninverting LVPECL output - complementary to Pin 6; differential swing defines logic state transitions |
Key Features
| Feature | Design Value |
|---|---|
| Any-differential-input compatibility | Supports LVDS, LVPECL, HSTL, and CML without external biasing or level translation |
| Temperature-compensated LVPECL outputs | Maintains stable VOH/VOL over −40°C to +85°C, eliminating need for external feedback or calibration |
| Low random jitter | ≤2psRMS added jitter preserves eye opening in 2.5Gbps+ serial links |
| Guaranteed 2GHz operation | Validated at fMAX ≥ 2.0GHz with VOH − VOL ≥ 250mV, ensuring margin for 10GbE KR/KX4 applications |
| Robust input common-mode range | 0.05V to (VCC − 0.05V) allows direct interfacing with diverse driver families across voltage domains |

Equivalent & Alternatives
The following parts are listed as comparable options for similar differential signal translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NB7L14M | Lower supply range (+2.375V to +3.6V); 2.5GHz fMAX; no HSTL input support | Optimized for ultra-low-power CML-to-LVPECL conversion in battery-backed modules | Select when operating below 2.5V or requiring lower ICC (<12mA) |
| Analog Devices ADN2880 | Integrated CDR functionality; higher power (32mA); 2.7Gbps data rate limit | Used where clock recovery is required alongside translation, e.g., optical line receivers | Select only if CDR capability is mandatory; not a drop-in replacement due to functional extension |
Compared with NB7L14M and ADN2880, the MAX9375EUA+T offers broader input standard compatibility (HSTL/LVDS/LVPECL/CML), tighter pulse skew (30ps vs. 45ps/60ps), and lower jitter (2psRMS vs. 2.5ps/3.1ps), making it optimal for multi-standard backplane interconnects where deterministic latency and minimal skew dominate design constraints.

FAQ
What is the absolute maximum supply voltage for the MAX9375EUA+T?
The MAX9375EUA+T has an absolute maximum VCC-to-GND rating of −0.3V to +4.1V. Operation outside this range risks permanent damage. For reliable function, maintain VCC between +3.0V and +3.6V per datasheet specifications. Exceeding +4.1V even momentarily may degrade internal bipolar junctions and compromise long-term reliability of the MAX9375EUA+T.
Can the MAX9375EUA+T accept single-ended inputs?
No, the MAX9375EUA+T is strictly a differential-input device. Its IN and IN pins form a matched pair requiring true differential signaling with minimum 100mV amplitude. Single-ended signals applied to either pin will not meet the input common-mode or differential threshold requirements, resulting in undefined output behavior. Proper operation of the MAX9375EUA+T demands differential source drivers such as LVDS or CML transmitters.
What termination is required for the LVPECL outputs of the MAX9375EUA+T?
The MAX9375EUA+T LVPECL outputs (OUT and OUT) must be terminated with 50Ω ±1% resistors to VCC − 2.0V. This Thevenin-equivalent termination establishes correct DC bias points and ensures fast, clean edges. Using 50Ω to ground or VCC violates output stage operating conditions and causes excessive current draw or logic level corruption in the MAX9375EUA+T.
Does the MAX9375EUA+T require external biasing resistors on its inputs?
No, the MAX9375EUA+T features internally biased differential inputs with rail-to-rail common-mode range (0.05V to VCC − 0.05V) and no external biasing components needed. Its input stage self-biases to accommodate LVDS, LVPECL, HSTL, and CML signals directly-eliminating the need for pull-up/down resistors, Thevenin networks, or AC-coupling capacitors in most implementations of the MAX9375EUA+T.
Is the MAX9375EUA+T pin-compatible with other devices in the MAX937x family?
Yes, the MAX9375EUA+T shares identical 8-pin µMAX pinout with MAX9374EUA+T and MAX9376EUA+T. All three devices use the same VCC, GND, IN/IN, and OUT/OUT assignments. However, functional differences exist: MAX9374 is dual-channel, MAX9376 adds enable control, and MAX9375EUA+T is single-channel without enable-so PCB layout reuse is possible but logic-level compatibility must be verified per application for the MAX9375EUA+T.
