Product details
Overview
The MAX9376EUB+T from Maxim Integrated is a fully differential, high-speed dual-level translator IC with one LVDS/anything-to-LVPECL channel and one LVDS/anything-to-LVDS channel, supporting signal rates up to 2.5GHz, featuring 421ps typical propagation delay, 30ps max pulse skew, and operation from a single +3.3V supply across -40°C to +85°C - deployed in backplane routing and DSLAM line cards.
For engineers reviewing the MAX9376EUB+T datasheet, MAX9376EUB+T pinout, MAX9376EUB+T application, or MAX9376EUB+T equivalent, this device serves as a critical interface for translating between legacy and modern differential signaling standards including LVDS, LVPECL, HSTL, and CML in telecom infrastructure and high-speed data links.
Technical Context
The MAX9376EUB+T implements two independent, fully differential translation paths: Channel 1 converts any compatible differential input (≥100mV) to LVPECL outputs terminated to VCC − 2.0V via 50Ω, while Channel 2 converts the same input to LVDS outputs compliant with ANSI EIA/TIA-644, terminated differentially with 100Ω. Both channels share a common input stage with rail-to-rail common-mode range (0.05V to VCC − 0.05V).
Its bipolar process enables fast edge rates (≤220ps rise/fall), low added jitter (≤2psRMS), and temperature-compensated LVPECL output levels - all while maintaining <600ps max propagation delay over full temperature and voltage range. Input compatibility spans LVDS, LVPECL, HSTL, and CML without external level-shifting circuitry.

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar differential level translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX9375EUB+ | Single-channel LVDS/anything-to-LVPECL only; no LVDS output channel | Suitable only where LVPECL output is needed without concurrent LVDS translation | Select when system requires only one translation direction and space/power constraints favor single-channel solution |
| SN65LVDS387DGK | LVDS-to-LVPECL only; no anything-input flexibility; 1.6GHz max rate; no LVDS output channel | Limited to LVDS input sources; lacks HSTL/CML compatibility and dual-output capability | Choose only for cost-sensitive LVDS-in/LVPECL-out use cases with lower speed requirements (<1.6GHz) |
Compared with MAX9375EUB+ and SN65LVDS387DGK, the MAX9376EUB+T uniquely delivers simultaneous LVPECL and LVDS outputs from a single differential input source, with broader input standard support and higher 2.5GHz bandwidth - making it irreplaceable in multi-protocol backplane and DSLAM designs requiring co-located translation paths.

FAQ
What signaling standards does the MAX9376EUB+T accept on its differential inputs?
The MAX9376EUB+T accepts LVDS, LVPECL, HSTL, and CML differential inputs directly - no external biasing or level-shifting required. Its input stage supports any differential signal within the supply rails and ≥100mV amplitude, with common-mode range from 0.05V to VCC − 0.05V. This universal input compatibility is confirmed in the MAX9376EUB+T datasheet's "Inputs" section and DC Electrical Characteristics table.
How should the LVPECL outputs of the MAX9376EUB+T be terminated?
The MAX9376EUB+T LVPECL outputs (OUT1, OUT1) must be terminated with 50Ω ±1% resistors connected to VCC − 2.0V (typical), not to ground or VCC. The datasheet specifies this Thevenin-style termination to establish correct DC bias and ensure fast transitions. Improper termination causes distorted waveforms or failure to meet VOH/VOL specifications - verified in Figure 3 and Applications Information section.
Does the MAX9376EUB+T support operation at 2.5GHz, and under what conditions?
Yes, the MAX9376EUB+T guarantees 2.0GHz minimum switching frequency and specifies 2.5GHz maximum for both LVPECL and LVDS outputs - provided VOH − VOL ≥ 250mV (LVPECL) or VOD ≥ 250mV (LVDS). This is documented in the AC Electrical Characteristics tables under fMAX, with test conditions explicitly defined for 3.3V supply and specified input amplitudes.
What is the purpose of the two separate input pairs (IN1/IN1 and IN2/IN2) on the MAX9376EUB+T?
The MAX9376EUB+T features two independent differential input pairs: IN1/IN1 drives the LVPECL output channel (OUT1/OUT1), while IN2/IN2 drives the LVDS output channel (OUT2/OUT2). This allows asynchronous or synchronous translation of two distinct signal sources - confirmed in the Pin Description and Detailed Description sections, where each input pair is assigned to a dedicated output channel.
Can the MAX9376EUB+T operate from a +3.0V supply, and how does that affect performance?
Yes, the MAX9376EUB+T operates across +3.0V to +3.6V - all DC and AC specifications are guaranteed over this full range. At +3.0V, LVPECL output voltage levels shift downward (e.g., VOH = VCC − 1.085V min), but remain within functional limits per the datasheet's DC Electrical Characteristics table. Propagation delay and jitter remain within spec, as confirmed in the Absolute Maximum Ratings and AC Electrical Characteristics sections.
