3 Description

The TS3DS10224 device is a bidirectional differential

crosspoint, 1:4, or 1:2 multiplexer and demultiplexer;

or fan-out switch for high-speed differential signal

applications (up to 720 Mbps). The TS3DS10224

logic table can route any input to any output creating

a wide range of possible switching or multiplexing

configurations. Common configurations include:

differential crosspoint switching, differential 1:4 mux,

or differential 2-channel 1:2 multiplexer and

demultiplexer. The TS3DS10224 offers a high BW of

1.2 GHz with channel RON of 13 Ω (typical).

The TS3DS10224 can also be used to fan out a

differential signal pair to two ports simultaneously

(fan-out configuration). The BW performance is lower

in this configuration.

The TS3DS10224 operates with a 3-V to 3.6-V power

supply. It features ESD protection of up to ±8-kV

contact discharge and 2-kV human-body model on its

I/O pins.

The TS3DS10224 provides fail-safe protection by

isolating the I/O pins with high impedance when the

power supply (VCC) is not present.
