Description

Pericom Semiconductor’s PI3USB3102 USB3.0 and USB2.0 Com-

bo Switch is a complete 1:2 switching solution for SuperSpeed

USB 3.0 signals. PI3USB3102 provides dierential high-speed

lanes for the USB3.0 4.8 Gbps TX and RX lanes as well as a dier-

ential lane for 480 Mbps USB 2.0 signals and the USB_ID signal.

PI3USB3102 can be used to connect two hosts to a single device

or a single host to two devices.

PI3USB3102 oers excellent signal integrity for high-speed sig-

nals and low power dissipation. Insertion loss is 1.7 dB and return

loss is -16 dB at 2.5 GHz. Power dissipation is 6.6 mW maximum.

Application

Routing of USB3.0 signals with low signal attenuation between

source and sink.

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.

4. Output 2 is for an output with internal conditions such that the output is high except when disabled by the output control.

5. All input impulses are supplied by generators having the following characteristics: PRR ≤ MHz, ZO = 50Ω, tR ≤ 2.5ns, tF ≤ 2.5ns.
