TI recommends a 4-layer PCB with a solid ground plane, and to keep the signal traces as short as possible. Additionally, it's essential to follow the recommended layout guidelines for the USB interface to ensure compliance with USB 2.0 specifications.
The TXU0101DRYR has built-in support for USB suspend and resume. To handle these events, the system should assert the SUSPEND pin low to enter suspend mode, and de-assert it to resume. The device will automatically enter low-power mode during suspend and wake up when resume is detected.
The TXU0101DRYR supports cable lengths up to 3 meters (10 feet) while maintaining compliance with USB 2.0 specifications. However, it's recommended to use high-quality, shielded cables to minimize signal degradation and ensure reliable operation.
The TXU0101DRYR is configured for high-speed operation by default. To configure it for full-speed operation, the HSFS pin should be tied low. Additionally, the device can be configured for high-speed operation with an external 27 MHz crystal oscillator or an internal 27 MHz oscillator.
The TXU0101DRYR has several power management options, including automatic power management, which allows the device to enter low-power mode when the USB bus is idle. Additionally, the device can be powered down using the PWROFF pin, and it has a built-in voltage regulator to generate the required internal voltages.
