TUSB1044: Will the TUSB1044 work as a USB-C sink for DisplayPort and USB 3 breakout connectors

Part Number: TUSB1044
Other Parts Discussed in Thread: TUSB1064, TUSB564

I'm looking for an alternate chip to the TUSB1064 for use on a device that would split it to a DisplayPort connector and USB 3 (USB3.1 + 2 Lane DP). I was looking into the TUSB1044 but was not sure if it will work for this purpose since the only examples I could find in the datasheet section 8.3.2 as well as the dev board showed the output only routed to a USB C.

Can the TUSB1044 in sink mode be used exactly like the TUSB1064? What are the differences between the two IC's?

Hi,

The TUSB1044 can work in both USB Type-C source and sink application as shown in section 8.3.2. However, the TUSB1044 does not have an internal MUX that can de-mux the Type-C into separate USB and DP. If you need separate USB and DP, then you need to use the TUSB564 or TUSB1064.

Thanks

David

Thanks David, I looked into TUSB564 and looks like its also pin compatible with the 1064 so would work well. Looks like the large difference between the two is this one has a lower bandwidth of 8.1gbps vs 10 on the 1064. Any other large differences between the two devices?

Hi,

Correct, the difference is in the bandwidth. The TUSB564 is intended to be used for USB3.2 Gen 1 5G while the TUSB1064 is intended to be used for USB3.2 Gen 2 10G.

Thanks

David
