Si5351 + PIC16F1455 USB controller
Nema STM32/PIC tu nikakve veze sa kontrolom i upravljanjem, njegov zadatak je samo da postavi fiksno delitelje tako da do XOR stignu bliske frekvencije, rekoh da se može menja opseg frekvencija, različito radi ako se postavi 10kHz, 100kHz, 1MHz, 10MHz ili bilo koji neka druga kombinacija deliteleja, drugačji je opseg hvatanja, druga je "strmina" detekcije, sa tim se praktičo menja PROCESNO POJAČANJE!

Kada to proradi STM/PIC bukvalno mogu da se odkače jer nadalje radi anlogni PID regulaciju temperature.
Postoji samo začkoljica pre nego što stigne na zadatu temperaturu kako se tad upravlja.

U upticaju su
1) Si5351A vrlo jeftin 0.8$, treba dva komada za full postavku
2) Si5351C, skuplji oko 3.9$, ima dva ulaza, slično kao pod 1)
3) CDCE6124, slično kao 2) oko 6$ ali ima EEPROM pa može da zapamti delitelje! Mozda se izbegne MCU!!!
4) LMK03318, LMK5B12204m vrlo sličnoo kao 3) samo ima manji jitter

BTW: Može bilo koja kombinacija neka dva fino granulirana programabilna delitelja, tehnički može da se napravi sve sa dva mala 8-pin PIC-a, mora dva jer svaki ima po jedan NCO (to je neka vrsta finog delitelja) i jedan PIC je sa TCXO dok je drugi sa XO, zajedno dolazi do 4046 i dalje se analogno to sve procesira.

Komparator je 74HC4046 zbog veće brzine (do 38MHz).

Grejač je Thermal Track sa OP-AMP, imamo to već ovde u temi samo signal dolazi sa LPF umesto sa temp senzora.

Dodatno opciono termalna zaštita sa LM10 preko interne diode od TT.
