We currently use the Cypress FX2 (CY7C68013)One option could be philips isp1504 or SMSC usb3300 + otg ip-core in low cost FPGA, that is at least working and available solution (I have tested both PHY's). Of course the relative price of the FPGA fabric for the HS OTG core is still relativly high. Antti Lukats

Are those parts generally available or just sampling? Also, do you know of a HS OTG core with the ULPI interface or did you map UTMI <-> ULPI yourself? Thanks, Rob

I think ISP1504 generic availability should be just "know" but I have actually not made any inquires for production. Philips is providing a UTMI - ULPI wrapper but it is not necessary to use it :) Antti

Also, when this IP core is inserted and compiled for the FPGA what clock speeds will be required in order to reduce the possibility of internal timing problems? We have an FPGA available that will be used for several other functions but it's currently unclear how many gates will be available for this IP core or any other additional functions. Brad S.

I have not seen any real small USB OTG IP Core solutions, and I also have never synthesised usb ip-cores as standalone only as part of FPGA softcore SoC system. my thumb guess would be that if your FPGA is S3-1500 or anything similar then you might have enough resources overleft. A 32 bit softcore RISC (microblaze) + some bus peripherals + hs usb ip core takes more than 60% of V2-1000. Thats my best estimates if those would help you. I dont think there is any usbhs otg ipcore really optimized for FPGA so its not yet cost effective option. For ASICs the gate-cost is smaller so its not such an issue. Antti news:openchip.org

I didn't realize that the usb3300 was the ULPI PHY and had nothing to do with the ip-core. Thanks for the clarification. It sounds like an FPGA-based solution isn't a cost-effective solution at this time. Developing an ASIC is not an option for us, so we will have to stay with any commercial USB hosting devices that become available in the near term. Brad.

You can download datasheet here: http://www.semiconductors.philips.com/pip/ISP1760BE.html. The part is marked "Full production", but I don't know if it's true or not. Tomorrow I'll give them a call.

Antonio, Thanks for the link. I downloaded the datasheet and it looks like we could use it but we only need one USB 2.0 port and this part has three (3) ports so it would definitely be overkill. Also, understandably, the part is large (128 pins) and we are trying to conserve as much power and PCB space as we call. If I remember right, I believe the ISP1761 only has one port but isn't available to the general public yet. I'll keep looking. Thanks for your help. Brad.
