Hi Andrey,
Thank you very much for your reply.
I try to find where to buy the TI160808U601 and TI201209-121 chokes. I do not know where I should find these. Would you know where I should order these components ?
By the way, do you confirm the ISSI SRAM is pin compatible with the Cypress chip ? http://www.digikey.com/product-detail/en/IS61NLP51236-200TQLI/706-1103-ND/15...
Is this ISSI chip fine for our application ? Is 18 MBit enough ? Do you confirm this ISSI chip is the best value for what we need ? Are you sure we cannot find a lower cost chip with similar performances and/or a better performances chip with similar cost ? Are you sure we will not need to reroute the PCB ?
We really need to be sure before starting the PCB production. If both you and Alexander confirm everything is fine, I will ask the fab to start the PCB.
Please let me know.
Again, thanks a lot for your help.
Best regards.
Jean-Samuel. :-)

Please inform me what actually rf chockes partnumbers are problem to order. Unfortunately MuRata produce few billion pcs and then stopped for a few years. So, possible we have to find some Chinese fab partnumbers to order.

Hi Jean-Samuel.
Unfortunately I have no internet connection now. Tomorrow I'll check flash and others.

some issue to source these.
Andrey is looking into this.
2/ Would you suggest a distributor for the GPS chip ?
Try contacting manufacturer directly: http://www.transystem.com.tw/product.php?b=g&m=pe&cid=4&sid=&...
They have a distributor in UK, but I think it might be easier to buy from the manufacturer directly: http://www.castlemicrowave.com/castle-contact.asp
This chip is popular in Russia, so it is easy to source them here, shipping them to EU might be a pain in big batches, but I think we could send few chips for this prototyping batch if manufacturer's lead time is too long. Here it costs $14.50/chip for more then 16 chips: http://www.compel.ru/infosheet/TSI/EB-570/
