MAX4986CTO+

Analog Switches - Special Purpose Overview

The MAX4986CTO+ is a single-lane SAS/SATA multiplexer/demultiplexer and redriver supporting data rates up to 6.0Gbps. It operates from a single +3.3V supply with typical standby current of 1mA. The device features independent programmable input equalization (0dB or 4dB) and output preemphasis (0dB or 3dB). Inputs and outputs include internal 50Ω terminations and require AC coupling. It supports SAS I/II/III and SATA out-of-band signaling, cable detection, and is housed in a 42-pin TQFN package.

Analog Switches - Special Purpose Feature Summary

• Active 2:1/1:2 multiplexing and demultiplexing for SAS/SATA signals
• Programmable input equalization and output preemphasis for signal integrity
• Integrated 50Ω input/output terminations and AC-coupling requirements
• Supports SAS/SATA out-of-band signaling with squelch functionality

Analog Switches - Special Purpose Applications

• PC Servers
• Workstations
• Desktops
• Docking Stations

Analog Switches - Special Purpose Procurement Notes

Verify the component's lead-free status and RoHS compliance against the datasheet specifications before integration. Confirm that the commercial temperature range (0°C to +70°C) aligns with the target system environment. Ensure proper power sequencing and grounding practices are followed during assembly to maintain signal integrity and device reliability.

Analog Switches - Special Purpose Selection Notes

Select this component for applications requiring a single-lane SAS/SATA switch with integrated signal conditioning. Consider the MAX4986ETO+ if an extended industrial temperature range (-40°C to +85°C) is required. Ensure the design accommodates the 42-pin TQFN footprint and provides adequate thermal relief for the exposed pad.

Analog Switches - Special Purpose Part Context

The MAX4986CTO+ belongs to the MAX4986 family of active multiplexer/demultiplexers designed for high-speed serial storage interfaces. It serves as a bridge between host controllers and storage devices, managing signal routing while compensating for channel losses through equalization and preemphasis capabilities.

Analog Switches - Special Purpose Replacement Considerations

The MAX4986ETO+ is a verified alternative within the same family, offering identical functionality but specified over an extended temperature range of -40°C to +85°C compared to the commercial range of the MAX4986CTO+.
