CMOS Digital Integrated Circuits Silicon Monolithic TDS5B212MX,TDS5C212MX
1. Functional Description
• 1-64GT/s 1-Lane Two Differential Channel, 2:1 Mux/1:2 De-Mux 2. General
TDS5B212MX, TDS5C212MX are high-speed differential channel multiplexer(Mux)/demultiplexer(De-mux)
switches. These devices are designed to support up to 64GT/s high-speed differential interface such as PCIe® 6.0,
CXL 3.x, USB4®Version 2.0, ThunderboltTM 5, DisplayPortTM 2.0.
TDS5C212MX and TDS5B212MX have different pin layout.TDS5C212MX has an optimized pin assignment to
achieve high frequency performance, while TDS5B212MX uses the same pin layout as conventional products.
The A Port(An+/An-) is conneceted 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 pins (OE). When the output enable (OE) is held at a
high-level, the switches are open (high-impedance state), regardless of the state of the select, thus these devices
have lower consumption current.
For device switch adjustment operations, Port A (An+, An-) has a weak differential resistance of 20 kΩ between
the positive and negative terminals (An+, An-), and a weak pull-down resistance of approximately 1 MΩ from
the An+ and An-terminals to GND.
The devices are designed to operate in temperatures from -40 to 125 � and can be used for application including
industrial use cases. 3. Features
