Pericom Semiconductor’s PI2USB3212 is a 1 to 2 bi-directional
differential channel multiplexer/demultiplexer switch supporting
5.0 Gbps applications, such as USB 3.0. Due to its low bit-to-bit
skew, high channel-to-channel noise isolation and high bandwidth,
this product is ideal for switching two sources to a single receiver,
or alternatively, one source to two receivers.

Notes:
1. CL = Load capacitance: includes jig and probe capacitance.
2. RT = Termination resistance: should be equal to ZOUT of the Pulse Generator
3. Waveform 1 is for an output with internal conditions such that the output is low except when disabled by the output control. Waveform 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 on transition per measurement.
