ISL35411DRZ-T7

Specialized Overview

The ISL35411DRZ-T7 is a quad de-emphasis driver designed for advanced protocols operating at data rates up to 11.1Gbps. It integrates high-speed drivers with built-in de-emphasis to compensate for frequency-dependent attenuation in PCB traces and twin-axial copper cables. The device operates on a single 1.2V supply, supporting per-channel throughputs from 10Gbps to 11.1Gbps using Current Mode Logic (CML) inputs and outputs. Key specifications include low power consumption of 90mW per channel, adjustable output de-emphasis, line silence preservation, and support for 64b/66b encoded data with long run lengths. It is housed in a compact 4mm x 7mm 46 Ld QFN package.

Specialized Feature Summary

• Integrates four high-speed drivers with limiting amplifiers and built-in de-emphasis for signal integrity compensation
• Supports straight route through architecture via CML input/output interfaces for simplified routing
• Features adjustable output de-emphasis and line silence preservation capabilities
• Operates on a single 1.2V power supply with low power consumption of 90mW per channel

Specialized Applications

• QSFP active copper cable modules
• InfiniBand (QDR) interconnects
• 40G Ethernet (40GBASE-CR4/SR4) links
• High-speed active cable assemblies
• High-speed printed circuit board (PCB) traces

Specialized Procurement Notes

Verify the obsolete status of the ISL35411DRZ-T7 before procurement planning. Confirm RoHS compliance details and check for End-of-Life notices such as PLC21060. Ensure that replacement strategies are evaluated due to the component's discontinued status. Validate packaging specifications and carrier types against current inventory records to avoid sourcing errors.

Specialized Selection Notes

Select this component when designing systems requiring quad channels with data rates up to 11.1Gbps. It is suitable for applications needing low latency and adjustable de-emphasis to mitigate trace attenuation. Consider pairing with the ISL36411 receive-side equalizer for active copper cable assemblies exceeding 15 meters. Ensure the design accommodates the 1.2V supply requirement and the 4mm x 7mm QFN footprint.

Specialized Part Context

The ISL35411 is part of Renesas' high-speed interface driver portfolio, specifically engineered for serial data transmission over lossy media. It complements the ISL36411 receiver to form complete link solutions for standards like DisplayPort v1.3, InfiniBand, and 40G Ethernet. The device addresses signal integrity challenges in high-density electronic systems by providing integrated equalization functions within a small form factor.

Specialized Replacement Considerations

Public confirmed substitute part numbers are not available. The ISL35411 series is marked as obsolete. Designers should evaluate alternative high-speed quad drivers from current Renesas portfolios or other manufacturers that support similar data rates and pin compatibility.
