Introduction

TOPVAR MAX398CSE+G55 is an integrated Analog Switch and Multiplexer, Demultiplexer IC, a product of Maxim Integrated. It is mainly aimed at applications requiring high accuracy signal routing, and is suitable for both single-ended and differential signal switching. This device integrates two low-capacitance analog switches, one high linearity multiplexer and one low-loss, low-noise demultiplexer into one single, 55-pin package. The parts included features a PCIe Gen3 lane budgeting with serial data rates up to 3.2Gbps and are designed to minimize crosstalk and connector expense while guarding against EMI emissions from the switch.

Features and Benefits

• Designed for PCIe Gen3 and USB 3.0 applications
• Cross-talk suppression and EMI emissions reduced
• Two low-capacitance analog switches
• High linearity multiplexer and demultiplexer
• Low-loss, low-noise operation
• 3 Amp load driving capability
• 9.92 mm X 9 mm footprint with lid
• Pin/pad compatible to USB 3.0 interface

Application Fields

The MAX398CSE+G55’s integrated analog switch and multiplexer, demultiplexer IC package offers advantages in applications such as PCIe slots, video streaming, USB 3.0 designs, monitor switching, and many more. Since the package is pin/pad compatible to USB 3.0, it is an ideal choice for those looking to incorporate analog switches and multiplexer/demultiplexer capabilities into existing USB 3.0 designs.

Working Principle

The operation of the MAX398CSE+G55 analog switch and multiplexer, demultiplexer IC is based upon the principle of electrical charge transfer. When a voltage is applied to one of the control inputs, the charged particles, or electrons, on the switch make it turn ON, allowing current to flow from one port to the other. When the voltage is removed, the switch turns OFF and the current flow is blocked until the voltage is reapplied.The multiplexer and demultiplexer functions work in the same way as the analog switch, with the addition of the ability to select different channels to route signals to and from. The multiplexer will accept multiple inputs and route them to a single output, while the demultiplexer takes a single input and routes it to multiple outputs.

Conclusion

The MAX398CSE+G55 is an ideal integrated analog switch and multiplexer, demultiplexer IC for applications requiring high precision routing of signals and port switching. Its features include cross-talk suppression, EMI reduction and 3 Amp load driving capability. The device is pin/pad compatible to USB 3.0 and can handle serial data rates of up to 3.2Gbps. Its integrated package is an ideal solution for those looking to incorporate analog switch and multiplexer/ demultiplexer capabilities into existing designs.
