Product details
Overview
ISL36411DRZ-T7 from Renesas (formerly Intersil) is a quad-channel receive-side lane extender IC designed for high-speed serial interconnects, supporting data rates up to 11.1 Gbps per channel with CML I/O, 1.2V single-supply operation, and programmable equalization boost up to 30 dB. It extends signal reach up to 10 m on 28 AWG twin-axial cable and preserves line silence for DisplayPort v1.3, USB 3.1 Gen 2, and InfiniBand QDR protocols.
For engineers reviewing the ISL36411DRZ-T7 datasheet, ISL36411DRZ-T7 pinout, ISL36411DRZ-T7 application, or ISL36411DRZ-T7 equivalent, key selection criteria include per-lane LOS detection, pin-selectable equalizer boost (0–8 levels), low latency (<500 ps), differential input impedance (80–120 Ω), and compatibility with 46-lead 4 mm × 7 mm QFN packaging for active copper cable modules.
Technical Context
The ISL36411DRZ-T7 implements four independent CML-based signal paths, each comprising a fixed-gain adjustable equalizer followed by a limiting amplifier. Its architecture supports protocol-transparent line-silence preservation via dual DT threshold pins (DT1 for channels 1–2, DT2 for channels 3–4) and individual LOSB indicators per lane.
Equalization is set externally using two CMOS control pin pairs (CP1A/B for lanes 1–2, CP2A/B for lanes 3–4), enabling deterministic, non-adaptive boost configuration without convergence delay. Input return loss meets -12 + 2√f (dB) up to 4.1 GHz and follows -6.3 + 13 log₁₀(f/5.5) (dB) from 4.1–11.1 GHz, ensuring robust high-frequency signal integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | Up to 11.1 Gbps per lane - enables HBR3 DisplayPort, USB 3.1 Gen 2, and 40GBase-CR4 compliance. |
| Supply Voltage | 1.2 V ±100 mV - single-rail operation simplifies power delivery in space-constrained cable assemblies. |
| Power Consumption | 440 mW total (110 mW/lane) - enables thermal management in dense QSFP+ and DP1.3 active cables. |
| Equalization Boost | 0–30 dB in 8 discrete levels - set via external CP pin logic, eliminating adaptation latency and pattern sensitivity. |
| Propagation Delay | 500 ps max per lane - ensures sub-nanosecond timing alignment critical for multi-lane synchronization. |
| Input Impedance | 80–120 Ω differential - matches standard 100 Ω PCB traces and twin-axial cable impedances. |
| LOS Response Time | 50 µs assert/deassert - provides fast, deterministic link status signaling for protocol-level error recovery. |
Pinout & Package
ISL36411DRZ-T7 is housed in a RoHS-compliant 46-lead QFN package (4 mm × 7 mm, 0.75 mm height, exposed thermal pad). Pin layout supports straight-through routing for minimal trace discontinuity in active cable paddle cards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD (Pins 1,5,9,13,24,27,28,31,32,35,36,39) | Power supply input | 1.2 V rail requiring local 10nF + 100pF decoupling per pin to suppress broadband noise above 100 MHz. |
| IN1[P,N]–IN4[P,N] (Pins 2–3,6–7,10–11,14–15) | Differential CML inputs | Accepts attenuated high-speed signals post-cable; DC-coupled with 100 nF blocking caps required. |
| OUT1[P,N]–OUT4[P,N] (Pins 25–26,29–30,33–34,37–38) | Differential CML outputs | Delivers restored 650 mVP-P signal to host ASIC; matched 100 Ω differential load required. |
| LOSB1–LOSB4 (Pins 4,8,12,16) | Active-low LOS indicators | Open-drain outputs pulled low when corresponding input falls below DT threshold - used for module fault reporting. |
| CP1A/B, CP2A/B (Pins 42–43,19–20) | Equalizer boost control | CMOS logic inputs setting 2-bit code per pair; internal 25 kΩ pull-down enables float/GND/VDD configuration. |
| DT1, DT2 (Pins 44,18) | Detection threshold reference | Analog voltage inputs defining mute threshold for lanes 1–2 and 3–4; set via external RDT (e.g., 15 kΩ for >12 dB loss). |
| GND (Pins 17,23,40,46) | Ground reference | Must connect directly to solid PCB ground plane; exposed pad also serves as primary thermal and electrical ground path. |
Key Features
| Feature | Design Value |
|---|---|
| Quad-channel lane extension | Four independent 11.1 Gbps paths in 4 mm × 7 mm footprint - enables compact QSFP+/DP1.3 active cable modules with straight-through routing. |
| Line silence preservation | Detects and mutes output during electrical idle without distorting quiescent state - essential for InfiniBand QDR and DisplayPort AUX channel integrity. |
| Deterministic equalization | Pin-selectable boost (0–8 levels) eliminates adaptation time and avoids false lock on pathological patterns - guarantees first-bit reliability. |
| Lane-specific LOS monitoring | Four dedicated LOSB outputs provide per-lane fault visibility - supports hot-plug diagnostics and link training in multi-lane optical/electrical modules. |
| Low-latency signal restoration | 500 ps propagation delay with <50 ps lane-to-lane skew - maintains timing alignment across all four lanes for coherent multi-lane protocols. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad-channel receive-side equalizer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ISL35411DRZ-T7 | Transmit-side quad driver (4× Tx) with 4 dB de-emphasis; 340 mW total power; no LOS support. | Targeted at active cable transmitter ends (e.g., host-side DP source), not receiver-side extension. | Select ISL35411DRZ-T7 only when implementing transmit equalization; not interchangeable with ISL36411DRZ-T7 due to opposite signal direction and missing Rx features. |
| QLX4600-SL30 | 6.25 Gbps quad Rx equalizer with 30 dB boost; includes 4 dedicated LOS pins but lacks DT threshold flexibility and line-silence preservation. | Designed for PCIe 2.0 and SAS-6Gb applications; insufficient bandwidth for 10+ Gbps protocols like USB 3.1 Gen 2. | Choose QLX4600-SL30 only for legacy 6 Gbps systems where lower power (312 mW) and simpler control suffice; not suitable for ISL36411DRZ-T7's 11.1 Gbps use cases. |
Compared with ISL35411DRZ-T7 and QLX4600-SL30, the ISL36411DRZ-T7 uniquely combines 11.1 Gbps capability, deterministic pin-selectable equalization, per-lane LOS reporting, and protocol-aware line-silence preservation-making it the sole option for next-generation DisplayPort v1.3, USB 3.1 Gen 2, and 40G Ethernet active cable receivers.

FAQ
What is the maximum supported data rate per channel for the ISL36411DRZ-T7?
The ISL36411DRZ-T7 supports up to 11.1 Gbps per channel, validated for NRZ signaling across protocols including DisplayPort v1.3 HBR3 (8.1 Gbps), USB 3.1 Gen 2 (10 Gbps), and 40G Ethernet (10.3125 Gbps per lane). This rating is specified under VDD = 1.2 V, TA = +25°C, and input amplitude of 600–1600 mVP-P, with performance confirmed via PRBS27-1 testing and oscilloscope eye analysis per FN6965 Rev 2.00.
Does the ISL36411DRZ-T7 support line-silence preservation for InfiniBand QDR?
Yes, the ISL36411DRZ-T7 explicitly supports line-silence preservation for InfiniBand QDR through its DT threshold detection and output muting circuitry. When input amplitude falls below the DT-set level, the limiting amplifier output is muted while holding common-mode voltage constant-preserving electrical idle states required for QDR link training and power management without disrupting protocol timing.
How is equalization boost configured on the ISL36411DRZ-T7?
Equalization boost on the ISL36411DRZ-T7 is configured using two external CMOS control pin pairs: CP1A/B sets boost for lanes 1–2, and CP2A/B sets boost for lanes 3–4. Each pair encodes an 8-level boost (0–30 dB) as a 2-bit value (e.g., GND/VDD = level 2), with internal 25 kΩ pull-down resistors enabling float/GND/VDD connections. No software or dynamic adaptation is involved-configuration is static and deterministic at power-up.
What package type and dimensions does the ISL36411DRZ-T7 use?
The ISL36411DRZ-T7 uses a 46-lead thin quad flat no-lead (TQFN) package measuring 4.0 mm × 7.0 mm × 0.75 mm with an exposed thermal pad. Per L46.4x7 package drawing, it features 0.4 mm pitch leads, 42 perimeter pads, and 4 corner pads, optimized for thermal dissipation and high-density routing in active cable paddle cards and module substrates.
Can the ISL36411DRZ-T7 be used in USB 3.1 Gen 2 applications?
Yes, the ISL36411DRZ-T7 is explicitly qualified for USB 3.1 Gen 2 (10 Gbps) applications, as stated in the datasheet's supported protocols list and Figure 1 typical application circuit. Its CML I/O, 100 Ω differential impedance, 0.35 UI residual jitter, and LFPS signal pass-through capability (down to 100 kHz) ensure full compatibility with USB 3.1 Gen 2 electrical specifications and link training requirements.
