Analog Switches - Special Purpose datasheet and documents for MAX4888AETI+G3U

MAX4888AETI+G3U

Analog Switches - Special Purpose Overview

The MAX4888AETI+G3U is a high-speed passive switch designed for routing PCI Express data between two destinations. It features four single-pole/double-throw (4 x SPDT) channels, supporting PCIe Gen I and Gen II data rates up to 5.0 Gbps. The device operates from a single +3.0V to +3.6V power supply with a maximum quiescent current of 120µA. Key electrical parameters include an on-resistance of 7Ω, same-pair skew of 7ps, turn-on time of 250ns, and turn-off time of 50ns. It is housed in a 28-pin TQFN package (3.5mm x 5.5mm) and functions within a temperature range of -40°C to +85°C.

Analog Switches - Special Purpose Feature Summary

Single digital control input (SEL) switches signal paths between common and normally open/closed terminals.
Low same-pair skew ensures minimal timing differences between differential signal lines.
Flow-through pin configuration simplifies PCB layout and impedance matching.

Desktop computers
Servers and storage area networks
Laptops

Analog Switches - Special Purpose Procurement Notes

Verify the component against official Analog Devices documentation to confirm specifications and compliance. Ensure the ordering suffix matches the required lead-free and RoHS-compliant packaging standards. Cross-reference the part number with authorized distributors to validate authenticity and availability status before procurement.

Analog Switches - Special Purpose Selection Notes

Select this component for applications requiring bidirectional switching of PCIe lanes. Verify that the system power supply falls within the specified +3.0V to +3.6V range. Consider the 28-pin TQFN package dimensions for board space constraints. Ensure ESD protection requirements are met during handling and assembly.

Analog Switches - Special Purpose Part Context

The MAX4888A belongs to the MAX4888A/MAX4889A family of high-speed passive switches. These devices are engineered for reallocating PCIe lanes in graphics applications, such as splitting a 16-lane bus into two 8-lane buses for SLI or CrossFire configurations. The family shares similar operational characteristics but differs in channel count and package size.

Analog Switches - Special Purpose Replacement Considerations
