The TMUXHS4212 is a generic analog differential passive mux or demux that can work for any high-speed interface with differential signaling where common mode voltage (CMV) and differential amplitude up to 1800 mVpp. It employs adaptive input voltage tracking that ensures the channel remains unchanged for the entire common mode voltage range. Two channels of the device can be used for electrical signals that have different CMV between them. Two channels can also be used in such a way that the device switches two different interface signals with different data and electrical characteristics.

Excellent dynamic characteristics of the device allow high speed switching with minimum attenuation to the signal eye diagram with very little added jitter. While the device is recommended for the interfaces up to 16 Gbps, actual data rate where the device can be used highly depends on the electrical channels. For low loss channels where adequate margin is maintained, the device can potentially be used for higher data rates.

The TMUXHS4212 is only recommended for differential signaling. However, certain low voltage single ended signaling (such as, Mipi DPHY LP signaling) can pass through the device. It is recommended to analyze the data line biasing of the device for such single ended use cases.

The TMUXHS4212 comes in two different pinout options that provide layout implementation choices.
