MF 10:39 PM PCB Development: RE: Is the USB SS connection correct?

> Pin 33/35 are connected to AC11/AD11 on the *FPGA* (USB_TXN/P0), with AC coupling (DC blocking) capacitor.
Will this one also be corrected as follows?
Incorrect: FPGA (USB_TXN/P0)
Correct: AM572x (USB_TXN/P0)

Hi Masayoshi,
It looks like there is an error in the datasheet.
Pin 33/35 are connected to AC11/AD11 on the FPGA (USB_TXN/P0), with AC coupling (DC blocking) capacitor.
Pin 27/29 are connected to AF12/AE12 (USB_RXN/P0) as straig... Michael Williamson

The J3Pin-Out (Table 7) of the MitySOM-AM57 System on Module data sheet describes the USB3.0 SuperSpeed terminals as follows.
Pin27 AC11 USB1_SSRX_N
Pin29 AD11 USB1_SSRX_P
Pin33 AF12 USB1_SSTX_N(2)
Pin35 AE12 USB1_SSTX_P(2)

TC 01:57 PM PCB Development: RE: about MECHANICAL INTERFACE in AM57x DataSheet

Thank you for pointing this out. We will repair the figure references in the next revision of the datasheet. In both cases the erroneous reference is to the figures directly below the text where the error appears. Thomas Catalino

MW 08:07 PM PCB Development: RE: Unconnected pins, board dimensions and hole positions

Hello.
1. Generally speaking, all of the MFIO pins are direct connects to the AM57xx CPU device and if they are unused in your design it is safe to leave them not connected. The Ball numbers are included in the table and can be cross... Michael Williamson

Posting on behalf of customer:
1.The J1 and J3 connectors of MitySOM-AM57 are described as “MFIO” for “Type”.
"If this pin is not used, can it be left unconnected?"
(Table 6, Table 7 in MitySOM-AM57_datasheet.pdf)
2.Is it okay... Thomas Catalino
