Jean-Samuel Najnudel - BJT PARTNERS SARL jsn at bjtpartners.comHi 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/1557418 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. :-) On Tue, Jul 3, 2012 at 11:40 PM, Andrey Sviyazov <andreysviyaz at gmail.com>wrote: > 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. > > Best regards, > Andrey Sviyazov. > (Sent from my mobile client) > 04.07.2012 1:22 пользователь "Andrey Sviyazov" <andreysviyaz at gmail.com> > написал: > > Hi Jean-Samuel. >> Unfortunately I have no internet connection now. >> Tomorrow I'll check flash and others. >> >> Best regards, >> Andrey Sviyazov. >> (Sent from my mobile client) >> >> 04.07.2012 1:10 пользователь "Alexander Chemeris" < >> alexander.chemeris at gmail.com> написал: >> > >> > On Mon, Jul 2, 2012 at 10:16 PM, Jean-Samuel Najnudel - BJT PARTNERS >> > SARL <jsn at bjtpartners.com> wrote: >> > > 1/ Would you know a distributor for the Murata chokes ?
