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.
