C2997437 based on SL2.2sUSB2.0 hub chip solution verification board

Overview

This solution verification board is used for functional verification of the SL2.2s USB2.0 hub chip with mall number C2684434. In this solution, USB5V is used for power supply, and the chip integrates 5V to 3.3V. Supports USB2.0 high speed (480MHz), USB2.0 full speed (12MHz), and low speed mode (1.5MHz), with four downstream ports. Supports automatic enumeration switching from self-powered to bus powered. A 12MHz crystal oscillator needs to be used externally. Use a multi-light solution. If there is no need to light the lights, just leave them floating. SL2.2s only supports I2C Master mode and can independently read customized data from external EEPROM. The EEPROM chip address is 0.
