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 highspeed

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 singleended

and differential signaling such as I2C, UART,

DisplayPort AUX, and USB2, just to name few.

The high-speed channel's dynamic characteristics

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 750μA. The device also offers a power-down mode

in which all channels become Hi-Z and the device

operates with minimal power of just 30μA.
