| PCIe (any version), usb 2.0 bridge ICs |
| (1/3) > >> |
| lk:
Greetings, I was planning to make my own PCI to USB adapter card, and naive as i was i just expected the bridge chips to be readily available. The only ones i found are 10 USD and up, and as i expect to fail several times before i make this work. I would like something that is cheaper. Does anyone know of an IC that might fit these requirements? I plan to hand solder it, so a package with leads would be appreciated. I have looked at asix, Diodes Inc and TI parts, all very expensive. Does anyone know of a chip that might work, i was surprised that the choices on digikey were so limited. br Lasse |

I assume what you mean is a USB host controller. These are indeed not readily available, and it's going to cost you a lot more than just finding a card. |

Hi, For PCI to USB2 check out the PLX (now Broadcom) part for $15.50 at Digikey. Manufacturer Part Number USB2380-AB25NI G Description IC CONTROLLER PCI USB 2.0 88QFN For PCIe to USB2 check out the PLX part below for $19.32: Manufacturer Part Number USB3380-AB50NI G Description IC CONTROLLER PCI USB 2.0 88QFN The above are USB endpoint controllers. For USB host controllers the silicon is a lot cheaper. Check out the Microchip part below for $1.30 at Digikey. Manufacturer Part Number USB3300-EZK Description IC USB HOST/OTG PHY ULPI 32-QFN Note that Microchip stole the PLX part number. :) |

The ASM1042 is a USB host controller. Not on Digikey but I find it on ebay for $4.38. https://www.ebay.com/itm/ASMEDIA-ASM1042-ASM-1042-QFN-64-IC-Chip-ASMT-USB-3-0-Extension/331728447596?hash=item4d3c8e686c:g:EJwAAOSwPcVVgn1~ The best I can tell, the ASM USB device controllers are SATA to USB. |
