Texas Instruments provides a recommended PCB layout in the TUSB2077A datasheet, which includes guidelines for component placement, routing, and thermal management. It's essential to follow these guidelines to ensure proper operation and minimize electromagnetic interference (EMI).
The TUSB2077APTRG4 is a USB 2.0 high-speed repeater, and it automatically detects the USB speed of the connected device. However, you can configure the device to operate in low-speed or full-speed mode by using the SPEED pin. You can also use the SUSPEND pin to put the device in a low-power state.
The TUSB2077APTRG4 can support cable lengths up to 5 meters (16.4 feet) while maintaining USB 2.0 high-speed operation. However, the actual cable length supported may vary depending on the quality of the cable, the environment, and the specific application.
To ensure EMC with the TUSB2077APTRG4, follow proper PCB layout and design guidelines, use shielding and grounding techniques, and implement EMI filtering and shielding on the USB cables. Additionally, ensure that the device is operated within its specified operating conditions and that the system is designed to meet relevant EMC standards.
The TUSB2077APTRG4 has a typical power consumption of 150 mA during high-speed operation and 50 mA during low-power mode. The device also has a shutdown mode that reduces power consumption to less than 1 mA.
