3 Description

The TMUXHS4612 is a high-speed bidirectional passive switch in mux or demux configurations. The device is protocol agnostic supporting many applications including HDMI 1.4 / 2.0 / 2.1, and DisplayPort 1.4 / 2.1. The TMUXHS4612 is a generic analog differential passive mux or demux that works for many high-speed differential interfaces with data rates up to 20Gbps. The TMUXHS4612 high-speed channels support differential signaling and single-ended signaling as long as the single-ended signals do not violate VP-N_ABSMAX parameter. The sideband channels are 5V tolerant and support single-ended and differential signaling such as I2C, UART, DisplayPort AUX, and USB2, just to name few. The dynamic characteristics of the high-speed channel allows high-speed switching with minimal attenuation to the signal eye diagram and with very little added jitter. The silicon design of the device is optimized for excellent frequency response at higher frequency spectrum of the signals. The device supports differential signaling with common-mode voltage range (CMV) of 0V to 3.6V in the Dxx datapaths.

The TMUXHS4612 consumes very low active power of 800μA. The device also offers a power-down mode in which all channels become Hi-Z and the device operates with minimal power of just 32μA.
