PI3USB304
3.3V USB 3.0 SuperSpeed
Dual 2:1 Mux/DeMux Switch with Enable
Description
Pericom Semiconductor’s PI3USB304 is a dual USB 3.0 2:1
switch.It can switch transmit and receive differential signals for
two 5 Gbps SuperSpeed USB 3.0 lanes.
Using advanced high-speed transmission gate technology,
PI3USB304 is bidirectional and offers both excellent signal
integrity and very low power.
-3 dB bandwidth is 8.2 GHz.Insertion loss is extremely low, only
1 dB at 2.5 GHz.All other ac parameters – return loss, crosstalk,
off isolation – lead the industry in performance.Power dissipation
is very small -- 0.5 mW typical (0.15 mA @ 3.3V)
Application
Routing USB 3.0 SuperSpeed signals.
