Product details
Overview
MAX3750CEE+ from Maxim Integrated is a +3.3V Fibre Channel port bypass IC optimized for 2.125Gbps arbitrated loop (FC-AL) topologies, featuring a high-speed multiplexer, mismatch-tolerant output driver, 10ps deterministic jitter, >1000mVp-p differential output swing, and on-chip 150Ω differential termination on all inputs and outputs. It enables hot-swap capability for storage devices in RAID/JBOD systems.
For engineers reviewing the MAX3750CEE+ datasheet, MAX3750CEE+ pinout, MAX3750CEE+ application, or MAX3750CEE+ equivalent, key selection criteria include FC-AL data rate compliance, low-jitter signal integrity in cascaded loops, thermal performance at 0°C to +70°C, QSOP-16 package layout compatibility, and TTL-level SEL control logic behavior.
Technical Context
The MAX3750CEE+ implements a dual-path analog multiplexer with TTL-selectable signal routing: low SEL routes IN± to OUT±, while high SEL routes LIN± to OUT±. Its internal 150Ω differential input termination and 150Ω back-termination on LOUT±/OUT± reduce external component count and improve impedance matching across vias and connectors.
Designed for FC-AL hot-swap operation, it supports cascaded topologies with deterministic jitter ≤10ps (peak-to-peak) and random jitter ≤1.6ps (RMS), while maintaining signal integrity under load mismatches typical of board-level interconnects and inductive connectors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | 2.125Gbps - fully compliant with Fibre Channel FC-AL Class 2 timing requirements. |
| Deterministic Jitter | 10ps peak-to-peak - ensures reliable bit-error-rate performance in multi-stage cascaded FC-AL loops. |
| Supply Voltage | +3.0V to +3.6V - operates from standard 3.3V rail with ±10% tolerance, no auxiliary supplies required. |
| Output Swing | >1000mVp-p differential - drives 150Ω FC-AL loads without external amplification or level-shifting. |
| Power Dissipation | 190mW total - includes output current; enables compact thermal design in dense storage controller PCBs. |
| Operating Temp | 0°C to +70°C - specified for commercial-grade mass storage enclosures and JBOD chassis environments. |
| Input Termination | 150Ω differential on IN± and LIN± - eliminates need for external termination resistors, reducing BOM and layout complexity. |
Pinout & Package
MAX3750CEE+ is housed in a 16-pin QSOP (Quarter-Size Outline Package) with 0.635mm lead pitch, 7.4mm × 5.0mm body size, and exposed pad not present. Pin 1 is located at top-left corner when notch faces up.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 5, 8, 16 | GND | Electrical ground reference for analog and digital sections; multiple pins minimize ground bounce in high-speed switching. |
| 2 | LOUT+ | Noninverted port data output - routed from LIN± path when SEL = high; differential pair with Pin 3. |
| 3 | LOUT- | Inverted port data output - forms 150Ω-terminated differential pair with Pin 2 for loop-through signaling. |
| 6 | OUT+ | Noninverted data output - driven by either IN± (SEL = low) or LIN± (SEL = high); differential pair with Pin 7. |
| 7 | OUT- | Inverted data output - completes differential output stage with Pin 6; supports hot-swap isolation during device insertion. |
| 9 | SEL | TTL-compatible select input - logic low enables IN±→OUT± path; logic high enables LIN±→OUT± path for port bypass control. |
| 10, 11 | LIN-, LIN+ | Noninverted/inverted port data input - receive upstream FC-AL loop signals; internally terminated to 150Ω differential. |
| 14, 15 | IN-, IN+ | Noninverted/inverted data input - accept local device TX signals; 150Ω differential termination reduces stub reflections. |
| 12, 13 | VCC | +3.3V supply - dual pins lower IR drop and improve PSRR for high-frequency analog core operation. |
Key Features
| Feature | Design Value |
|---|---|
| Hot-swap–enabled port bypass | Enables seamless insertion/removal of storage devices in live FC-AL loops without disrupting upstream/downstream traffic. |
| On-chip 150Ω differential termination | Eliminates four external 150Ω resistors per device, reducing PCB area and improving signal fidelity at 2.125Gbps. |
| Mismatch-tolerant output driver | Stable operation despite impedance discontinuities from board vias, connector inductance, or unterminated stubs. |
| Low 10ps deterministic jitter | Preserves eye opening in multi-stage cascaded FC-AL configurations, supporting ≥3-tier loop expansion. |
| TTL-level SEL control | Direct interface with microcontroller GPIO or FPGA logic without level-shifting; compatible with 3.3V CMOS I/O standards. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Fibre Channel port bypass applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX3751CEE+ | 1.0625Gbps data rate, 180mW power, identical pinout and feature set except reduced speed. | Targeted at legacy FC-AL systems operating at 1x speed (1.0625Gbps), not 2x speed (2.125Gbps). | Select MAX3751CEE+ only when system bandwidth requirement is strictly ≤1.0625Gbps and backward compatibility is mandatory. |
| SY88932LHC | 2.5Gbps data rate, +3.3V supply, but lacks integrated 150Ω input/output termination and SEL-controlled dual-path mux. | Requires external termination and signal routing logic; suited for custom high-speed serial links beyond FC-AL spec. | Choose SY88932LHC only if higher bandwidth (2.5Gbps) is needed and board space permits added discrete components. |
Compared with MAX3751CEE+, the MAX3750CEE+ delivers 2× FC-AL bandwidth at marginally higher power (190mW vs. 180mW), while SY88932LHC offers greater speed headroom but increases BOM cost and layout complexity due to missing on-chip termination and mux logic.

FAQ
What is the maximum data rate supported by the MAX3750CEE+?
The MAX3750CEE+ supports a maximum data rate of 2.125Gbps, fully compliant with Fibre Channel arbitrated loop (FC-AL) Class 2 specifications. This rate is confirmed in the AC Electrical Characteristics table of the official datasheet, where "Data Rate" is specified as 2.125Gbps for the MAX3750 variant. The MAX3750CEE+ does not support 1.0625Gbps operation - that is exclusive to the MAX3751CEE+.
Does the MAX3750CEE+ require external termination resistors?
No, the MAX3750CEE+ integrates 150Ω differential termination on all inputs (IN±, LIN±) and back-termination on all outputs (OUT±, LOUT±), eliminating the need for external resistors. This is explicitly stated in the Features section and verified in Figures 2–5 of the datasheet schematic. External termination is only required if interfacing with non-standard impedances outside the FC-AL 150Ω specification.
How does the SEL pin control signal routing in the MAX3750CEE+?
The SEL pin on the MAX3750CEE+ is a TTL-compatible control input: when pulled low, it routes the IN± input pair to the OUT± output pair; when pulled high, it routes the LIN± input pair to OUT±. This dual-path selection enables flexible port bypass and loop-through configurations. The behavior is documented in the Pin Description and Circuit Description sections, with timing validated under AC conditions.
What is the operating temperature range for the MAX3750CEE+?
The MAX3750CEE+ is rated for operation from 0°C to +70°C, as specified in the Ordering Information table and Absolute Maximum Ratings section. This commercial temperature grade aligns with typical mass storage enclosure environments. It is not rated for extended industrial (–40°C to +85°C) operation - that range applies to the unreleased/unlisted MAX3750 variant without the "E" suffix.
Is the MAX3750CEE+ pin-compatible with the MAX3751CEE+?
Yes, the MAX3750CEE+ and MAX3751CEE+ share identical 16-pin QSOP packaging, pin configuration, and electrical interface - including identical VCC, GND, SEL, IN±, LIN±, OUT±, and LOUT± assignments. This pin compatibility is confirmed in the Pin Configuration diagram and Ordering Information table. However, they differ in data rate (2.125Gbps vs. 1.0625Gbps) and power consumption (190mW vs. 180mW), so functional substitution requires system-level bandwidth validation.
