PCIe has a working frequency well into the GHz. --- End quote --- Not knowing high frequency PCB design has never stopped the guys who are making those cheap boards. I have one particularly bad PCI to SATA controller at home where one channel has a choice of either internal or external connector. They just split the SATA signals and wired them to both connectors, resulting in a 3 cm or so stub no matter which connector was used! With 1.5 Gbps signals! :palm: No wonder it never worked well. |

Hey, sorry for digging out this ancient thread. I am searching for something like this for a hobby project right now and wasn't very successfull. Has somebody found more chips until now? I basically want something, that allows me to stick a single USB Device directly into the PCIe Bus. So a single channel PCIe to USB converter. The goal is to connect one of TIs nice USB Sound Card Chips using PCI-express. I basically want to build my very own audiophool pci-e soundcard. Since I don't know anything about the digital part of this hole idea I am looking for a simplest solution with premade drivers that just works plug and play. Is there something in existence that works like that? The price for this chip isn't really a problem since I just want to build this thing for fun. |

I can't think of any machine that has PCIe but not USB. Just get a PCIe USB card, desolder one of the USB sockets, and build your sound card on that. But why not make a S/PDIF or HDMI connected unit instead? (In the latter case, buy a HDMI audio extractor and replace the DAC in it with a better one.) |

Part of the Challenge I put myself on is the Pci-e Connection. Sure, I could just repurpose an usb expander, but where is the fun in that? ;) |
