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 singleended

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.
