Hello community,

i found some inconsistence in the LS1088A RM.

The figure below shows that the LS1088A has a USBCLK-Input, but i can't find anything about that Input in the Datasheet.

But the LS1088A Datasheet says:

Does the LS1088A has such an USB-Clock-Input ?

Best regards,

Juergen

The LS1088a USB controllers are the same as LS1043a or LS1046a USB controllers. See the Section 3.13.4 of the LS1043 Datasheet:

USB 3.0 SSPHY needs a reference clock. There are two options for the reference clock: SYSCLK or DIFF_SYSCLK/DIFF_SYSCLK_B.


Have a great day,
