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)

Notes:
1. CL = Load capacitance: includes jig and probe capacitance.
2. RT = Termination resistance: should be equal to ZOUT of the Pulse Generator
3. Output 1 is for an output with internal conditions such that the output is low except when disabled by the output control. output 2 is for an output with internal conditions such that the output is high except when disabled by the output control.
4. All input impulses are supplied by generators having the following characteristics: PRR ≤ MHz, ZO = 50Ω, tR ≤ 2.5ns, tF ≤ 2.5ns.
5. The outputs are measured one at a time with one transition per measurement.
