A couple of days ago, I was tasked to create a PCB that essentially converts power from a USB-C to a firewire socket. A rough schematic was made and a custom footprint was created for the anticipated firewire female port. Yesterday, the Schematic was updated from a reference workflow doesn't have a footprint for the IEEE1394 (firewire) female port. So a suitable part was researched for this project and one was found on mouser here and Digikey as well, here . This is the 929 by Keystone Electronics. This datasheet schematic was used to make a custom footprint for the 929. Here's the custom footprint.
