Texas Instruments provides a recommended PCB layout in the datasheet, but it's also recommended to follow the layout guidelines in the application note 'TS3USB221 PCB Layout Guidelines' (SLVAUH5) for optimal performance.
To ensure signal integrity, follow the guidelines in the datasheet for impedance matching, termination, and routing. Additionally, use a signal integrity analysis tool to simulate the signal transmission and identify potential issues.
The maximum cable length supported by the TS3USB221DRCRG4 depends on the specific application and the type of cable used. As a general guideline, the device can support cable lengths up to 3 meters for USB 2.0 and 1 meter for USB 3.0. However, it's recommended to consult the USB specification and perform testing to determine the maximum cable length for a specific application.
To configure the TS3USB221DRCRG4 for USB 3.0 operation, set the MODE pin to a logic high and ensure that the device is powered from a 3.3V supply. Additionally, follow the guidelines in the datasheet for impedance matching and termination to ensure reliable operation at high speeds.
The power consumption of the TS3USB221DRCRG4 depends on the operating mode and the frequency of operation. According to the datasheet, the typical power consumption is around 150mA for USB 2.0 operation and 250mA for USB 3.0 operation. However, it's recommended to consult the datasheet and perform testing to determine the actual power consumption for a specific application.
