Analog Switches - Special Purpose datasheet and documents for MAX4889BETO+T

MAX4889BETO+T

Analog Switches - Special Purpose Overview

The MAX4889BETO+T is a high-speed passive switch designed to route PCI Express (PCIe) data between two destinations in desktop or notebook PCs. It features four double-pole/double-throw (4 x DPDT) switches, ideal for switching four half lanes of PCIe data. The device operates from a single +3.0V to +3.6V power supply and supports PCIe Gen I, Gen II, and Gen III data rates up to 8.0Gbps. Key electrical parameters include an on-resistance of 6.4Ω typical at VCC = +3.0V, a turn-on time of 80ns, and a propagation delay of 50ps. It is housed in a 42-pin TQFN package with dimensions of 3.5mm x 9.0mm.

Analog Switches - Special Purpose Feature Summary

Supports PCIe Gen I, Gen II, and Gen III data rates
Features superior return loss better than -10dB typical at 5.0GHz
Utilizes a single digital control input (SEL) to switch signal paths

Analog Switches - Special Purpose Applications

Desktop PCs
Notebook PCs
Servers
Video Graphics Cards—SLI and CrossFire

Analog Switches - Special Purpose Procurement Notes

Verify the component against official Analog Devices datasheets to confirm pinout compatibility and RoHS compliance. Ensure that the operating voltage range aligns with your system's power supply specifications. Check for any specific thermal management requirements due to the exposed pad design.

Analog Switches - Special Purpose Selection Notes

Select this component when routing high-speed differential signals like PCIe or SAS in compact designs. Consider the 42-pin TQFN package size for space-constrained applications. Evaluate the need for Gen III support if higher bandwidth is required compared to lower-generation alternatives.

Analog Switches - Special Purpose Part Context

This part belongs to the MAX4889 family of high-speed passive switches. It is specifically engineered for PCIe lane reallocation in graphics cards and motherboards. The 'ETO+' suffix indicates the TQFN package and lead-free/RoHS-compliant status.
