ʻO nā pōmaikaʻi o nā Oscillators Sine Wave OCXO
Haʻahaʻa haʻahaʻa loa ka wela wela
Hoʻohana nā OCXO i keʻena wela mau no ka hoʻomalu pono ʻana i ka mahana aniani ma kahi kikoʻī (e like me ka wela o ka helu inflection o kahi aniani ʻokiʻoki AT-), e hoʻopau ana i nā hopena o ka loli ʻana o ka wela ambient ma ka pinepine. ʻO ko lākou kūpaʻa wela ke piʻi maʻamau i ± 0.01 ppb/degere a ±0.1 ppb/degere, ʻoi aku ka maikaʻi ma mua o nā oscillator kristal maʻamau (TCXOs mai ± 1 ppb/degere a ±10 ppb/degere).
-Ui Loa
Hoʻohana nā OCXO hawewe -haʻahaʻa i ka -noise amplifier haʻahaʻa a me -kiʻekiʻe kiʻekiʻe -kiʻekiʻe no ka hoʻopaneʻe ʻana i ka leo ʻāpana i -160 dBc/Hz ma 10 kHz (haʻahaʻa loa ma mua o ka -140 dBc/Hz ma 10 kHz o kahi TCXO). Hōʻike ka walaʻau ʻana i ka manawa pōkole -paʻa alapine a pili pono i ka ratio signal-to-noise (SNR) o nā ʻōnaehana RF.
Kaulana -Loaʻi
Hoʻohana nā OCXO i nā kristal maʻemaʻe kiʻekiʻe a me ka hōʻailona hermetically sealed e hōʻemi i ka ʻelemakule i ±0.05 ppb/makahiki a i ±0.5 ppb/makahiki (ma waena o nā TCXO mai ±1 ppb/makahiki a i ±5 ppb/makahiki). Hōʻike ka helu ʻelemakule i ka neʻe pinepine ʻana i ka manawa a pili pono i ke ola o ka mīkini.
Kūʻē Kūʻē
Hoʻohana ka OCXO i ka ʻano umu -lua (he ʻauʻau wela o loko a me ka umu ma waho) e hoʻokaʻawale i ke kaiapuni, e hōʻoia ana i ka hana paʻa i loko o ka laulā -40 degere a +85 degere (e hana mau nā TCXO mai -20 degere a +70 degere).
Waiwai kū hoʻokahi
Hoʻopuka ka hawewe sinus{0}}OCXO i kahi hōʻailona sinusoidal maʻemaʻe<-80dBc), resulting in lower electromagnetic interference (EMI) and a higher signal-to-noise ratio (SNR) compared to square-wave OCXOs (harmonic distortion <-40dBc).
Ke ʻano o nā Oscillators OCXO Wave Sin
AT-ʻoki i nā OCXO
ʻO kēia ka mea i hoʻohana pinepine ʻia i ka ʻoki aniani. ʻO kona alapine -ka wela wela he parabola cubic, a ma lalo o ka mana thermostat, hiki iā ia ke hoʻokō i kahi koena wela haʻahaʻa loa (maʻamau.<±0.1 ppb/°C).
SC-ʻoki i nā OCXO
ʻOi aku ka palahalaha o ke alapine (frequency) -pie wela, me ka helu helu haʻahaʻa e like me ±0.01 ppb/degere, e kūpono ana ia mau mea no nā kaiapuni wela loa.
IT-oki OCXO
Aia ke alapine (frequency)-anu wela ma waena o ka AT-oki a me SC-keke. ʻOi aku ka maikaʻi o kona kūpaʻa wela ma mua o ko AT-ʻoki ʻoki ʻia akā ʻoi aku ka nāwaliwali ma mua o ko SC-nā kristal ʻokiʻoki. Ua like kona walaau me ko AT-okioki kristal, a he haahaa kona kumu kuai.

Hoʻolaha Satellite
Hāʻawi nā OCXO hawewe -Sine i nā hōʻailona oscillator kūloko no nā transponder ukali. ʻO kā lākou leo haʻahaʻa haʻahaʻa e pale i ka intermodulation distortion i ka wā o ka hui ʻana o ka hōʻailona, e hōʻoia i ka maikaʻi o ke kamaʻilio.
Kuantum Computing
Pono ka ho'ololi 'ana i ka Qubit i ka pololei o ka manawa nanosecond-level. ʻO ka haʻahaʻa haʻahaʻa loa o ka hawewe -sinina OCXO (<50 fSec) ensures the synchronization of laser pulses and reduces decoherence errors.
Ho'āʻo pololei a ana
ʻO nā ʻOCXO hawewe -Sine ma ke ʻano he kumu kuhikuhi ma nā mea nānā kikoʻī a me nā mea hoʻoponopono pūnaewele, a ʻo kā lākou paʻa alapine e pili pono i ka pololei o ka hoʻāʻo.
Kuʻuna Hana o nā Oscillators OCXO Oscillators
ʻO ke kumu o kahi OCXO ka umu. Ke hoʻohana nei kēia umu i kahi mea hoʻomehana no ka mālama ʻana i ka quartz crystal resonator a me kona kaapuni a puni i kahi mahana mau (maʻamau 20-40 degere ma luna o ka wela ambient), e hoʻopau ana i nā hopena o ka loli ʻana o ka mahana ma ke alapine aniani. ʻo kahi laʻana:
Hoʻonohonoho i ka umu hoʻokahi-:Hāʻawi ka umu -papa hoʻokahi i ka paʻa wela o ±0.1 degere a ±0.5 degere, kūpono no nā noi hoʻomalu ʻoihana.
Hoʻonohonoho ʻelua- umu (e like me ka Yangxing Technology YOV5050DP):Mālama pono ka umu i loko i ka mahana aniani, ʻoiai ka umu o waho e hoʻokaʻawale i ke keʻakeʻa ambient, e loaʻa ana ka paʻa wela o ±0.01 degere. He kūpono kēia hoʻonohonoho no nā noi kikoʻī loa e like me ka hoʻokele satellite.
Maʻemaʻe hōʻailona:ʻO ka hōʻailona hoʻopuka o ka hawewe sine OCXO he hawewe sine mau me ka ʻole o ka distortion harmonic (THD maʻamau <-80dBc), me ka leo haʻahaʻa haʻahaʻa loa (maʻamau -150dBc/Hz @ 10kHz offset).
Ka hoohalike ana me na huinaha -hawewe OCXO:Hoʻololi nā OCXO o ka nalu huinaha - i nā nalu ʻālike me ka hoʻohana ʻana i ka mea hoʻohālikelike. He mea kūpono kēia no nā kaapuni kikohoʻe (e like me nā hoʻokomo uaki FPGA), akā hoʻokomo lākou i ka jitter hou (e hoʻonui ana i ka walaʻau ma kahi o 10-20%). Hoʻopuka pololei ʻo Sine-OCXO i nā hōʻailona analog a ʻoi aku ka maikaʻi no nā kaapuni analog a i ʻole nā noi alapine kiʻekiʻe (e like me nā hui RF).
Paʻa pinepine
• Pōkole -Paʻa Paʻa (Allan Variance): Hōʻike i nā loli pinepine i loko o 1 a 100 kekona. Hiki ke ho'okō i ka -pa'a pōkole o ka hawewe sine-OCXO<1×10⁻¹² (1-second threshold).
• Kūpaʻa -Loaʻa: Hoʻopilikia ʻia e ka ʻelemakule aniani, ʻo ka helu maʻamau he ±0.5 ppb/makahiki. Hiki ke ho'emi 'ia nā kŘkohu ki'eki'e (e like me ka -lua OCXO) i ±0.1 ppb/makahiki ma o ka 'oihana kaapuni uku.
Ka leo walaau
• ʻO ka walaʻau o ka pae he metric kumu no ke ana ʻana i ka maʻemaʻe alapine o kahi oscillator. Hōʻike maʻamau ka puʻe walaʻau o ka hawewe OCXO he 1/f³ ma ka ʻāpana alapine haʻahaʻa, kahi pali 1/f² ma waena o ka ʻāpana alapine -a me ka leo keʻokeʻo ma ka ʻāpana alapine kiʻekiʻe.
Ka Amplitude Output a me ka Impedance
• Amplitude Output: ʻO ka amplitude pukana o ka hawewe sine -OCXO maʻamau he 0.5 Vpp a 5 Vpp (hiki ke hoʻololi ʻia), loaʻa ma o ka mea hoʻonui i loko.
• Hoʻopili i ka hoʻokuʻu ʻana: ʻO ka maʻamau 50Ω output impedance e pili ana i nā kaula RF a me nā mea kani e hōʻemi i nā poho noʻonoʻo.
Noʻonoʻo noʻonoʻo o nā Oscillators OCXO Sine Wave
Ka hoʻopololei ʻana i ka walaʻau
Pono ka ripple lako mana<20mV (peak-to-peak). A low-noise LDO (such as the LT3045) or DC-DC converter is recommended, along with a π-type filter (LC filter, L = 10μH, C = 0.1μF + 10μF).
Hoʻohālikelike Hoʻouka
Pono e hoʻouna ʻia ka puka o ka hawewe sine OCXO ma o ke kaula coaxial 50Ω e pale aku i ka noʻonoʻo ʻana i nā hōʻailona ma muli o ka impedance mismatch. Inā he impedance kiʻekiʻe ka ukana (e like me ka hoʻokomo oscilloscope), pono e hoʻopili ʻia kahi resistor 50Ω ma ke ʻano me ka hopena.
Palekana Electromagnetic
Pono e hoʻopili ʻia ka OCXO i loko o kahi pūʻolo metala (e like me ke alumini a i ʻole ke keleawe), a pono e hoʻopili maikaʻi ʻia ka hale me ka ʻāina PCB e hana i kahi hale Faraday a hoʻopaʻa i ka hoʻopili electromagnetic waho (EMI).
