Texas Instruments provides a recommended PCB layout in the datasheet, but it's essential to follow good PCB design practices, such as keeping the signal traces short and away from noise sources, using a solid ground plane, and placing decoupling capacitors close to the device.
To ensure signal integrity, use controlled impedance traces, minimize trace lengths, and use 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 TS3USB221ARSERG4 depends on the specific application and the type of cable used. As a general guideline, the device supports cable lengths up to 3 meters for USB 2.0 and 1 meter for USB 3.2 Gen 1. However, it's recommended to consult the datasheet and perform signal integrity simulations to determine the maximum cable length for a specific application.
To configure the TS3USB221ARSERG4 for USB 3.2 Gen 2 operation, set the MODE pin to a logic high state and ensure that the device is powered from a 3.3V supply. Additionally, use a USB 3.2 Gen 2-compliant cable and ensure that the signal traces are designed to support the higher data rates.
The power consumption of the TS3USB221ARSERG4 depends on the operating mode and the data rate. According to the datasheet, the typical power consumption is around 150 mA for USB 2.0 operation and 250 mA for USB 3.2 Gen 1 operation. However, it's recommended to consult the datasheet and perform power consumption simulations to determine the exact power consumption for a specific application.
