Functional Description

? 1-32Gbps 1-Lane Two Differential Channel, 2:1 Mux/1:2 De-Mux

General

TDS4A212MX, TDS4B212MX are high-speed differential channel multiplexer(Mux)/demultiplexer(De-Mux)

switches. These devices are designed to support up to 32Gbps high-speed differential interface such as PCIe?

5.0, CXL 2.0, USB4? Version 2.0, ThunderboltTM 4, DisplayPortTM 2.0.

TDS4A212MX and TDS4B212MX have different pinout. TDS4B212MX has an optimized pinout to achieve high

frequency performance, on the other hand TDS4A212MX's pinout is easy to use for board layout.

The A Port (An+, An-) is connected to either the B Port (Bn+, Bn-) or C Port (Cn+, Cn-), which is determined by

the combination of both the select (SEL) and output enable (OE).When the output enable (OE) is held at a highlevel,

the switches are open (high-impedance state), regardless of the state of the select, thus these devices have

lower consumption current.

All pins are equipped with protection circuits to protect from electrostatic discharge damage.

Features
