AD9833 Waveform Generator
#6
Jos jednom pohvale, svidja mi se kako je sve ispalo tako kompaktno a i signali su odlicni za taj nivo konstrukcije.

Evo jos malo da zabiberim : ), uspravo mi "javili" iz Silicon Labs da pustaju novi generator Si5332, bruka, do 12 nezavisnih kanala do 350MHz, ima u chipu integrisan oscilator (kvarcni ili MEMS ne znam) a karakteristike sa 175fs RMS phase jitter tek da zagolicaju ... : )

Spominjem jer je isto I2C device i moze tu da se zakaci sa malo dorade u firmware, sprava "bije" ko blesava ako ti treba tako cist i precizan pravougaoni oblik za vrlo visoke frekvencije, sve ispod toga moze i malac Si5351 i ovaj AD9833 da zavrsi posao.

----
Si5332

• Embedded 50 MHz crystal option
• Input frequency range:
• External crystal: 16 to 50 MHz
• Differential clock: 10 to 250 MHz
• LVCMOS clock: 10 to 170 MHz
• Output frequency range:
• Differential: 5 to 333.33 MHz
• LVCMOS: 5 to 170 MHz

Strasno tj predivno, ovo se zakaci na Morio MV89 ili neki slicni duplo temperaturno kontrolisani OCXO (sa Ebay) i dobijete fenomenalnu spravicu sa vrlo vrlo ozbiljnim karakteristikama, 12 nezavisnih kanala sa 0ppm greske u delitelju i sa stabilnoscu generisane frekvencije u nekoliko ppb.
