iskreno EI mi deluje sporiji od kineza za prototip (a znatno je skuplji), od kineza dvostranu dobijes za 2-5 nedelja sto nije mnogo drugacije u odnosu na ono sto sam cuo za Ei .. po znatno nizoj ceni ... a za vise slojeva, jbg .. nisu tu ni kinezi jeftini (4 Layer 5cm*5cm 10pcs - $65)

Nije direktno vezano za temu, u pitanju je Clock kao nezaobilazna komponenta uz bilo koji eksterni ADC/DAC i evo jedan nov dokument koji se bavi problemom i nacinima resavanja Jitter-a:

Citat:
As clock speeds and communication channels run at ever higher frequencies, engineers who have previously had little need to consider clock jitter and phase noise are finding that they need to increase their knowledge of these subjects. This primer provides an overview of jitter, offers practical assistance in making jitter measurements, and examines the role of phase-locked loops (PLLs).

Ovo sa Audio AD konvertorom mi polako prelazi u totalno drugi domen :). Mislim da cu odustati sa Audio ADC-ovima jer je vec neko vreme vrlo aktuelna varijanta sa brzim ADC-ovima od nekih 3Mbsp iz ultra jeftinog USB DVB-T prijemnika (RTL2832U) koji ima prakticno sve sto treba u sebi. Evo ovde link iz SDR teme gde smo se uhvatili te zaludjice :)
