Product details
Overview
MAX9375EUA from Maxim Integrated is a fully differential, single-channel LVDS/anything-to-LVPECL translator IC designed for high-speed signal routing in backplane and network infrastructure. It supports up to 2GHz switching frequency, delivers 421ps typical propagation delay, maintains ≤30ps pulse skew, operates from +3.3V supply, and drives 50Ω LVPECL transmission lines - enabling precise timing in DSLAM and WAN line cards.
For engineers reviewing the MAX9375EUA datasheet, MAX9375EUA pinout, MAX9375EUA application, or MAX9375EUA equivalent, key selection criteria include guaranteed 2GHz operation, LVDS/LVPECL/HSTL/CML input compatibility, temperature-compensated LVPECL output swing, ±100mV differential input threshold, and ESD robustness (>2kV HBM) for industrial backplane environments.
Technical Context
The MAX9375EUA implements a bipolar-based differential comparator architecture with emitter-follower LVPECL outputs requiring external 50Ω termination to VCC − 2.0V. Its input stage accepts differential signals from 100mV to 3.0V amplitude across 0.05V to (VCC − 0.05V) common-mode range, ensuring interoperability with LVDS, CML, HSTL, and legacy LVPECL sources.
Output timing performance is stabilized via on-chip temperature compensation, delivering consistent VOH/VOL levels (VCC − 1.025V / VCC − 1.810V typ) and ≤2psRMS random jitter at 1.34GHz. Propagation delay variation remains within ±30ps over −40°C to +85°C, supporting deterministic signal integrity in synchronous backplane designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switching Frequency | 2.0GHz min - enables full-rate operation in OC-48/STM-16 and 10G Ethernet PHY interfaces |
| Propagation Delay | 421ps typ - ensures sub-nanosecond timing alignment critical for multi-lane parallel backplane routing |
| Pulse Skew | 30ps max - minimizes differential pair timing mismatch to preserve eye opening at 2Gbps |
| Differential Input Threshold | ±100mV - guarantees reliable switching with low-amplitude LVDS and CML sources |
| LVPECL Output Swing | 595–725mV diff - meets JEDEC JESD8-12A LVPECL voltage compliance for 50Ω-terminated loads |
| Supply Range | +3.0V to +3.6V - compatible with standard 3.3V logic rails and tolerant of board-level voltage droop |
| ESD Protection | ≥2kV HBM - provides robust handling during board assembly and field service in telecom equipment |
Pinout & Package
The MAX9375EUA is housed in an 8-pin µMAX package (3.05mm × 3.05mm × 0.8mm), thermally enhanced with exposed paddle, optimized for high-frequency signal integrity and compact backplane layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8 | VCC | Positive supply rail - requires dual ceramic bypass (0.1µF + 0.01µF) placed adjacent to pins for high-frequency noise suppression |
| 2 | IN | Noninverting differential input - accepts LVDS, CML, HSTL, or any rail-swing differential signal ≥100mV |
| 3 | IN | Inverting differential input - forms matched pair with Pin 2; trace length matching required for skew control |
| 4, 5 | GND | Power ground reference - low-inductance connection essential to minimize ground bounce at 2GHz |
| 6 | OUT | Inverting LVPECL output - must be terminated with 50Ω ±1% to VCC − 2.0V for valid static/dynamic levels |
| 7 | OUT | Noninverting LVPECL output - paired with Pin 6; identical termination required to prevent common-mode distortion |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed 2GHz operation | Validated minimum switching frequency ensures reliable use in OC-192/STM-64 line interface modules |
| Input standard agnosticism | Single device replaces multiple translators for LVDS, LVPECL, HSTL, and CML - reduces BOM count and layout complexity |
| Temperature-compensated outputs | Maintains stable VOH/VOL across −40°C to +85°C - eliminates need for external calibration in outdoor telecom cabinets |
| Low pulse skew (≤30ps) | Preserves differential timing margin in multi-gigabit serial links where skew directly impacts BER |
| High ESD immunity (≥2kV HBM) | Withstands handling and system-level transients without latch-up or parameter shift in field-deployed equipment |

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 max frequency (1.5GHz), higher supply current (25mA), same 8-pin SOIC package but no µMAX footprint | Limited to OC-48/STM-16 systems; not suitable for 10G Ethernet PHY clocking | Select when cost sensitivity outweighs 2GHz requirement and SOIC layout is already fixed |
| Analog Devices ADN2880 | Higher propagation delay (550ps typ), wider supply range (+2.7V to +3.6V), integrated 50Ω termination resistors | Better suited for portable test equipment; lacks guaranteed 2GHz spec and HSTL input support | Prefer for battery-powered instrumentation where internal termination simplifies layout, not for telecom backplanes |
Compared with NB7L14M and ADN2880, the MAX9375EUA uniquely combines 2GHz guaranteed bandwidth, ±100mV input threshold, and µMAX footprint - making it the only option qualified for space-constrained, high-density DSLAM and optical shelf designs requiring deterministic sub-500ps delay.

FAQ
What is the maximum guaranteed operating frequency of the MAX9375EUA?
The MAX9375EUA is guaranteed to operate up to 2.0GHz under all conditions across −40°C to +85°C, with typical performance reaching 2.5GHz. This specification is validated per AC Electrical Characteristics in the official datasheet and applies directly to the MAX9375EUA in its 8-pin µMAX package with proper 50Ω termination.
Does the MAX9375EUA support LVDS input signals?
Yes, the MAX9375EUA fully supports LVDS inputs: its differential input stage accepts signals with ≥100mV amplitude and common-mode range from 0.05V to (VCC − 0.05V), which aligns with ANSI TIA/EIA-644-A LVDS specifications. The MAX9375EUA datasheet explicitly lists LVDS among supported standards alongside LVPECL, HSTL, and CML.
What termination is required for the LVPECL outputs of the MAX9375EUA?
The MAX9375EUA LVPECL outputs (Pins 6 and 7) require 50Ω ±1% termination to VCC − 2.0V. This may be implemented as two discrete 50Ω resistors to a dedicated VT rail or as an equivalent Thevenin network. The MAX9375EUA datasheet mandates identical termination on both outputs to avoid distortion and ensure specified VOH/VOL levels.
Is the MAX9375EUA pin-compatible with other devices in the MAX937x family?
No - the MAX9375EUA is a single-channel translator in 8-pin µMAX. Other members like MAX9376 (dual-channel) use 16-pin packages and different pinouts. The MAX9375EUA datasheet confirms no pin compatibility exists across the family; each variant has unique pin mapping and thermal pad configuration.
What is the supply current consumption of the MAX9375EUA at 3.3V?
The MAX9375EUA draws 12mA to 18mA supply current (ICC) over temperature at VCC = +3.3V, with typical value of 18mA at +25°C. This is measured with all pins open except VCC and GND, and is specified in the DC Electrical Characteristics table of the MAX9375EUA datasheet - not extrapolated or estimated.
