Quick Start

Figure 2. Quick Start Evaluation

1. Connect the PC to the USB connector J3 through a USB cable.
2. Make sure the 3.3-V LDO output is enabled by opening J8 without a jumper.
3. Make sure the TS3USB221/A/E IC is enabled by shunting J7 with a jumper.
4. Connect two USB downstream devices (for example, mouse, keyboard, USB memory stick, etc) to J4

and J5 on the EVM.

5. To select USB downstream device 1 connected to J4, make sure J6 is shunted with a jumper. To

select USB downstream device 2 connected to J5, make sure J6 is open without a jumper.

6. Connector J1 and J2 are connected together without a USB switch. This through-path can serve as a

reference to compare with the TS3USB221/A/E path.
