Texas Instruments provides a recommended PCB layout in the datasheet, but it's also recommended to follow general high-speed PCB design guidelines, such as using a solid ground plane, minimizing trace lengths, and using 50-ohm transmission lines.
To ensure signal integrity, use a well-designed PCB with controlled impedance, minimize signal routing, and use signal termination resistors as recommended in the datasheet. Additionally, use a common mode filter or a common mode choke to reduce electromagnetic interference (EMI).
The maximum cable length supported by the TS3USB221DRCR depends on the specific application and the type of cable used. However, as a general guideline, the USB 2.0 specification recommends a maximum cable length of 3 meters (10 feet) for high-speed devices.
The TS3USB221DRCR has a specific power sequencing requirement, which is outlined in the datasheet. In general, the device should be powered up in the following sequence: VCC, then VCCIO, and finally the input signals. Power-down sequencing should be in the reverse order.
The recommended operating temperature range for the TS3USB221DRCR is -40°C to 85°C, as specified in the datasheet. Operating the device outside of this range may affect its performance and reliability.
