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.
