1 Features
3 Description
•
Provides bidirectional passive 2:1 MUX / 1:2
DEMUX for four differential channels
Data rate support up to 20 Gbps
Supports PCI Express 4.0 up to 16 Gbps
Also supports USB 3.2, USB 4.0, TBT 3.0, DP 2.0,
SATA, SAS, MIPI DSI/CSI, FPD-Link III, LVDS, SFI
and Ethernet Interfaces
–3-dB differential BW of 13 GHz
Excellent dynamic characteristics for PCIe 4.0
signaling
The TMUXHS4412 is a high-speed bidirectional
passive switch which can be used for both multiplexer
(mux) and demultiplexer (demux) configurations. The
TMUXHS4412 is a analog differential passive mux or
demux that works for many high-speed differential
interfaces for data rates up to 20 Gbps including PCI
Express 4.0. The device can be used for higher data
rates where electrical channel has signal integrity
margins. The TMUXHS4412 supports differential
signaling with common mode voltage range (CMV) of
up to 0 to 1.8 V and with differential amplitude up to
1800 mVpp. Adaptive CMV tracking ensures the
channel through the device remains unchanged for
the entire common mode voltage range.

Adaptive common mode voltage tracking
Supports common mode voltage up to 0 to 1.8 V
Single supply voltage VCC of 3.3 or 1.8 V
Ultra low active (320 μA) and standby power
consumption (0.1 μA)
Industrial temperature option with –40° to 105°C
Pin-to-pin PCIe 4.0 linear redriver option with
DS160PR421 and DS160PR412
The excellent dynamic characteristics of the
TMUXHS4412 result minimum attenuation to the
signal eye diagram with very little added jitter. The
device's silicon design is optimized for excellent
frequency response at higher frequency spectrum of
the signals. Its silicon signal traces and switch
network are matched for best intra-pair skew
performance.
