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, 190mW total power consumption, and integrated 150Ω differential on-chip 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 signal integrity at 2.125Gbps, low-jitter cascaded timing performance, on-chip termination compatibility with 150Ω differential interfaces, and QSOP-16 thermal/power behavior across 0°C to +70°C operation.
Technical Context
The MAX3750CEE implements a TTL-controlled 2:1 multiplexer routing either IN± or LIN± to OUT± and LOUT±, with SEL logic selecting between local (IN→OUT) and loop-through (LIN→OUT) paths. Its output stage drives both differential output ports (OUT± and LOUT±) simultaneously with >1000mVp-p swing into 150Ω loads.
Internal 150Ω differential input termination on IN± and LIN± eliminates external resistors, while on-chip 150Ω back-termination on OUT± and LOUT± reduces reflections from board vias and inductive connectors-critical for maintaining signal fidelity in multi-drop FC-AL cascades.

Pinout & Package
MAX3750CEE is housed in a 16-pin QSOP package (5.3mm × 10.2mm, 1.0mm height), with exposed pad not electrically connected. Pin pitch is 0.65mm; lead finish is lead-free (RoHS-compliant).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 5, 8, 16 | GND | Electrical ground reference for analog and digital sections; multiple pins reduce ground impedance |
| 2 | LOUT+ | Noninverted differential output for loop-through path; driven when SEL = High |
| 3 | LOUT- | Inverted differential output for loop-through path; pairs with LOUT+ for FC-AL return channel |
| 6 | OUT+ | Noninverted differential output for local port; driven when SEL = Low |
| 7 | OUT- | Inverted differential output for local port; pairs with OUT+ for FC-AL transmit channel |
| 9 | SEL | TTL-level select input controlling multiplexer path; Low = IN→OUT, High = LIN→OUT |
| 10, 11 | LIN-, LIN+ | Differential loop-in input with internal 150Ω termination; receives upstream FC-AL data |
| 14, 15 | IN-, IN+ | Differential local input with internal 150Ω termination; connects to disk drive TX/RX |
| 12, 13 | VCC | +3.3V supply input; dual pins reduce IR drop and improve PSRR at 2.125Gbps |
Key Features
| Feature | Design Value |

Applications
| Fibre Channel Arbitrated Loop Node | RAID Controller Bypass Interface |
|---|---|
Use Scenario: A Fibre Channel host bus adapter connects to multiple disk drives via an arbitrated loop, where each drive must be individually bypassed upon failure or removal. IC Role / Device Role / Timing Role: MAX3750CEE acts as a transparent port bypass switch, rerouting loop traffic around inactive or absent drives while maintaining signal integrity at 2.125Gbps. Use Value: Enables zero-downtime maintenance by preserving loop continuity without manual reconfiguration or physical rewiring. | Use Scenario: A RAID controller board integrates multiple MAX3750CEE devices to manage bidirectional FC-AL traffic between controller ASIC and up to eight JBOD enclosures. IC Role / Device Role / Timing Role: Each MAX3750CEE provides independent local-port and loop-through signal routing under SEL control, enabling dynamic topology reconfiguration. Use Value: Reduces FPGA I/O resource usage and simplifies timing closure by offloading FC-AL signal switching to dedicated bypass ICs. |
| Mass Storage Backplane Interconnect | Cascaded FC-AL Expansion Chassis |
Use Scenario: A 1U storage chassis uses a passive backplane with daisy-chained FC-AL traces; each slot hosts a disk drive with integrated MAX3750CEE. IC Role / Device Role / Timing Role: MAX3750CEE serves as the interface between backplane differential pairs and drive transceivers, providing on-die termination and drive strength matching. Use Value: Achieves consistent 2.125Gbps eye diagrams across all slots without per-slot tuning or external termination networks. | Use Scenario: An enterprise storage array expands capacity using three stacked FC-AL expansion chassis, each containing eight drives and one MAX3750CEE per drive. IC Role / Device Role / Timing Role: MAX3750CEE operates in cascade mode, passing signals through successive LOUT±/LIN± ports while maintaining sub-10ps deterministic jitter per stage. Use Value: Supports full 2.125Gbps bandwidth across 24-drive configurations without link degradation or protocol timeouts. |
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 termination architecture | Designed for legacy FC-AL systems operating at half-speed; not suitable for 2.125Gbps Class 3 links | Select MAX3751CEE only when backward compatibility with 1x FC speed is required and jitter margin allows |
| SY88932LKC | 2.5Gbps data rate, 3.3V supply, but requires external 100Ω termination and lacks integrated back-termination | Used in SFP-based optical modules; no native support for FC-AL electrical signaling or hot-swap control logic | Choose SY88932LKC only for non-FC-AL 2.5G serial links where board space permits external termination |
Compared with MAX3751CEE and SY88932LKC, the MAX3750CEE uniquely combines 2.125Gbps FC-AL compliance, integrated 150Ω differential termination on all ports, and SEL-driven hot-swap bypass logic-making it the only drop-in solution for commercial-grade FC-AL storage node designs requiring zero-layout-change upgrades from legacy systems.

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 Class 2 and Class 3 arbitrated loop specifications. This rate is verified under standard operating conditions (VCC = +3.3V, TA = +25°C) with deterministic jitter held to 10ps peak-to-peak. The MAX3750CEE does not support higher rates such as 4.25Gbps or 8.5Gbps, and its AC performance is not characterized beyond 2.125Gbps.
Does the MAX3750CEE require external termination resistors?
No, the MAX3750CEE does not require external termination resistors. It integrates 150Ω differential termination on all four differential ports: IN±, LIN±, OUT±, and LOUT±. This on-chip termination eliminates the need for eight discrete 150Ω resistors per device, reducing PCB layout complexity and improving signal integrity consistency across production units.
How does the SEL pin control signal routing in the MAX3750CEE?
The SEL pin on the MAX3750CEE is a TTL-compatible control input that selects the active signal path: when SEL is logic low, the device routes signals from IN± to OUT± and LOUT±; when SEL is logic high, it routes signals from LIN± to OUT± and LOUT±. This enables dynamic switching between local port and loop-through modes without interrupting FC-AL traffic flow.
What is the thermal performance of the MAX3750CEE in a 16-QSOP package?
The MAX3750CEE in 16-QSOP has a maximum continuous power dissipation of 667mW at +70°C ambient, with a thermal derating factor of 8.3mW/°C above that temperature. Measured supply current is ~57mA at +25°C and rises to ~84mA at +70°C, confirming stable operation within commercial temperature range without forced airflow or heatsinking in typical storage backplane layouts.
Is the MAX3750CEE pin-compatible with the MAX3751CEE?
Yes, the MAX3750CEE and MAX3751CEE share identical 16-QSOP packaging, pin configuration, and electrical interface-including matching VCC, GND, SEL, IN±, LIN±, OUT±, and LOUT± assignments. However, they differ in data rate (2.125Gbps vs. 1.0625Gbps) and power consumption (190mW vs. 180mW), so substitution requires verification of system-level timing and protocol compliance.
