Overview
The TMUXHS4412IRUAR from Texas Instruments is a high-speed, analog differential passive multiplexer (MUX) and demultiplexer (DEMUX) designed to support various high-speed differential interfaces. This device is capable of handling data rates up to 20Gbps, making it suitable for applications requiring high-speed signal switching with minimal signal degradation.
The TMUXHS4412IRUAR can be configured as either a 2:1 MUX or a 1:2 DEMUX for four differential channels, supporting interfaces such as PCI Express 4.0, USB 3.2, USB 4.0, Thunderbolt 3.0, DisplayPort 2.0, SATA, SAS, MIPI DSI/CSI, FPD-Link III, LVDS, SFI, and Ethernet.
The device features adaptive common-mode voltage tracking, ensuring that the signal integrity is maintained across the entire common-mode voltage range of 0V to 1.8V. It operates with a single supply voltage of either 3.3V or 1.8V and has ultra-low power consumption in both active and standby modes.
