TUSB2077A: OSC ppm requirement

Part Number: TUSB2077A

Tool/software:

Hi, 

My customer would like to use TUSB2077A in their project.

According to the spec, customer can choose 6M OSC/CRYTAL or 48M OSC/ external CLK source by setting the MODE pin.

 

Question for OSC selection, I can’t find any description about the OSC ppm requirement.

Can you help to review it and provide some suggestion?

 

Best regards,

Randy
