MAX14980ETO+T

Signal Buffers, Repeaters, Splitters Overview

The MAX14980ETO+T is a quad SAS/SATA redriver with equalization, designed for high-speed serial data transmission. It operates as a 6G/PS (PCIe Gen2) compatible signal conditioner to overcome channel losses. The device integrates four bidirectional channels within a single TQFN-HYBRID-42 package. It supports a supply voltage range of 3.0V to 3.6V and functions reliably across an industrial temperature range from -40°C to +85°C. This component serves as a signal integrity solution for storage and peripheral interfaces requiring robust signal regeneration.

Signal Buffers, Repeaters, Splitters Feature Summary

• Integrates four independent bidirectional redriver channels with programmable equalization capabilities.
• Designed to compensate for transmission line losses in high-speed serial data paths.
• Utilizes a compact TQFN-HYBRID-42 package to reduce layout complexity compared to discrete solutions.

Signal Buffers, Repeaters, Splitters Applications

• SAS (Serial Attached SCSI) interconnects
• SATA (Serial ATA) storage links
• PCI Express Gen2 signal conditioning

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the specific suffix 'T' against official Analog Devices documentation to confirm tape-and-reel packaging status, as datasheets may list the 'ETO+' variant without explicit reel specifications. Confirm RoHS compliance details directly from the manufacturer's environmental declaration. Cross-reference the part number with current discontinuation notices, as legacy Maxim Integrated products may have altered availability or end-of-life status.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component when designing systems requiring signal regeneration for 6Gbps serial links. Ensure the PCB trace length and loss characteristics necessitate active equalization rather than passive components. Verify that the system power budget accommodates the specified supply voltage range. Consider the thermal performance within the TQFN-HYBRID-42 package relative to the board's copper area and airflow conditions.
