The TUSB4041I-Q1 device accepts a crystal input to drive an internal oscillator or an external clock source. If a clock is provided to the XI pin instead of a crystal, the XO pin is left open. Otherwise, if a crystal is used, the connection must follow these guidelines. Because the XI and XO pins are coupled to other leads and supplies on the PCB, keep traces as short as possible and away from any switching leads. Minimize the capacitance between the XI and XO pins by shielding C1 and C2 with the clean ground lines.
