Si5351 + PIC16F1455 USB controller
Vidi, ne mogu da ga napravim kao što ga Rus napravio, nema šanse! Ni približno ... Smile

Tu je termodinamika veoma bitna, to je tako uskladjeno sa težinom/masom/površinom i svaka komponenta je veoma specifično izabrana i uskladjena ne samo električno nego i termički, da li je pozitivan/negativan koeficijent neke tu komponente, nije svima linearna zavistnost i treba ukrstiti tako koliko kriva, pa onoliko koliko ima komponenti tu, treba ukrstiti 20-30 kriva tako da se u jednoj vrlo specificnoj tački oni svi prelome i "nadju" na nekoj tamo izabranoj temperaturi ne znam, na primer na tačno 75*C i tada se dobije tražena stabilnost sa tamo nekim decimalama od PPM, počinje da se koristi PPB merna jedina (Part Per Bilion)

Double-oven ima to sve isto samo fizički dve kutice u kutici za Ultra High Stability OCXO timebase!

Da uzmeš šemu i da precrtaš i da pokušaš da to repliciras isto tako, kako god, NEMA TEORIJE da radi kao to sokoćalo, prvo specilano rezani kristal pa nadalje ...

Taj oscilator je prvi u klasi posle Rubidiumskim oscilatora/standarda, najčešće se koriste za GSM 2/3/4/5G+ Bazne stanice i kod DIY spravica... Ultra mali fazni šum ... Pogledaj DS Morion MV89a ...
Kupuju se isključivo korišćeni/polovni primerci ako negde upecaš ... Smile

Koji god Morion-ov OCXO da najdeš i probaš bićeš prezadovoljan (naravno da je ispravan) ...

To + LMK + GPS = Programabilna (8 kanala) Vremanska/frekvetna referenca, super-mega dobra kratkoročna i dugoročna stabilnost sa/bez GPS.
Fazni šum je u "fazonu" kao kod Macole i BatoMM sa THD "izmerite sami" Smile .. pa se ispostavi da nemaš opremu kako bi to mogao da izmeriš jer je toliko nizak i da bi mogao da izmeriš trebao bi ti bar 10x bolji oscilator tvoje merne sprave a to prelazi u domen "Science Fiction" ...
