I-Microchip Technology bc637PCI-V2 GPS Ilungelelaniswe kwi-PCI Ixesha kunye neProsesa yeFrequency

Ulwazi lweMveliso

I-bc637PCI-V2 yi-GPS edibeneyo, ixesha le-PCI kunye ne-frequency processor ebonelela ngexesha elichanekileyo kunye ne-frequency kwi-host computer kunye ne-peripheral data acquisition systems. Imodyuli ifumana ixesha elichanekileyo ukusuka kwinkqubo yesathelayithi yeGPS okanye kwiimpawu zekhowudi yexesha. Ungqamaniso lweGPS lwenza ukuba imodyuli ibe yeyona iwotshi ilungileyo yokulungelelanisa ngokuchanekileyo iikhompyuter ezininzi kwi-UTC. Imodyuli ixhasa ukuveliswa kwekhowudi yexesha elibanzi kunye noguqulelo kunye neziphumo ze-IRIG A, B, G, E, IEEE 1344, NASA 36, XR3, okanye 2137 kuzo zombini. ampi-litude modulated (AM) kunye neefomathi zokutshintsha kwenqanaba le-DC (DCLS). Umguquli ufunda kwaye angasetyenziselwa ukuqeqesha i-oscillator ye-10 MHz ukuya kwi-AM okanye i-DCLS ifomathi ye-IRIG A, B, G, E, IEEE 1344, NASA 36, XR3, okanye i-2137 iikhowudi zexesha. Imodyuli kwakhona ine-state-of-the-art ngqo digital synthesizer (DDS) izinga synthesizer ekwaziyo 0.0000001PPS ukuya 100MPPS.

Imodyuli inomsebenzi ophambili wokwenza ukuphazamiseka kwibhasi yePCI ngamaxabiso acwangcisiweyo. Olu phazamiseko lunokusetyenziselwa ukungqamanisa usetyenziso kwikhompyutha engumamkeli kunye nomqondiso weziganeko ezithile. Igalelo langaphandle lefrikhwensi likwayinto ekhethekileyo evumela ixesha kunye nokuphindaphinda kwemodyuli ukuba ithathwe kwi-oscillator yangaphandle enokuthi iqeqeshelwe (DAC vol.tage controlled) ngokusekelwe kwireferensi yegalelo elikhethiweyo.

Isishwankathelo
I-Microchip GPS ebhekiselele kwimodyuli yexesha le-bc637PCI-V2 inika ixesha elichanekileyo kunye nokuphindaphinda kwikhompyutheni yokusingatha kunye neenkqubo zokufumana idatha ye-peripheral. Ixesha elichanekileyo lifunyanwa kwinkqubo yesathelayithi yeGPS okanye kwiimpawu zekhowudi yexesha. Ungqamaniso lwe-GPS lubonelela nge-170 ns RMS ngexesha elichanekileyo kwi-UTC (USNO) kwaye yenza ukuba i-bc637PCI-V2 ibe yeyona iwotshi ifanelekileyo yokulungelelanisa ngokuchanekileyo iikhompyuter ezininzi kwi-UTC.
Embindini wokusebenza kwemodyuli yi-oscillator ye-TCXO 10 MHz eqeqeshekileyo ibonelela ngewotshi yexesha lemodyuli ye-100-nanosecond. Ixesha langoku (iintsuku ukuya kwi-100 ns) inokufumaneka kuyo yonke ibhasi ye-PCI ngaphandle kweendawo zokulinda zebhasi ye-PCI, evumela izicelo zexesha eliphezulu kakhulu. I-oscillator ekhethiweyo ebhodini okanye ngaphandle kwebhodi ye-10 MHz iqhuba i-frequency yemodyuli kunye nexesha lekhowudi ye-enerator circuitry. Ukuba ireferensi yegalelo ilahlekile, imodyuli iya kuqhubeka nokugcina ixesha (flywheel) ngokusekelwe kwinqanaba elikhethiweyo le-oscillator ye-10 MHz. Ukuba amandla alahlekile, i-RTC exhaswa yibhetri iyafumaneka ukugcina ixesha.
Ukuveliswa kwekhowudi yexesha elide kunye noguqulelo luyaxhaswa. Iziphumo zejenereyitha nokuba IRIG A, B, G, E, IEEE 1344, NASA 36, XR3, okanye 2137 kuzo zombini. ampi-litude modulated (AM) kunye neefomathi zokutshintsha kwenqanaba le-DC (DCLS). Umguquli ufunda kwaye angasetyenziselwa ukuqeqesha i-oscillator ye-10 MHz ukuya kwi-AM okanye i-DCLS ifomathi ye-IRIG A, B, G, E, IEEE 1344, NASA 36, XR3, okanye i-2137 iikhowudi zexesha.
Imodyuli kwakhona ine-state-of-the-art ngqo digital synthesizer (DDS) izinga synthesizer ekwaziyo 0.0000001PPS ukuya 100MPPS. Imodyuli isenokucwangciswa
ukuvelisa uphazamiseko olunye ngexesha elimisiweyo ngokusekelwe kuthelekiso lwexesha
(strobe). Isici sokubanjwa kwexesha lesiganeko sibonelela ngendlela yokubeka ixesha lesiganeko sangaphandle.
Inqaku eliphambili le-bc637PCI-V2 kukukwazi ukuvelisa ukuphazamiseka kwibhasi ye-PCI kwiireyithi ezicwangcisiweyo. Olu phazamiseko lunokusetyenziselwa ukungqamanisa usetyenziso kwikhompyutha engumamkeli kunye nomqondiso weziganeko ezithile.
Igalelo langaphandle lefrikhwensi liyinto ekhethekileyo evumela ixesha kunye nokuphindaphinda kwe-bc637PCI-V2 ukuba ithathwe kwi-oscillator yangaphandle enokuthi iqeqeshelwe (DAC voltage controlled) ngokusekelwe kwireferensi yegalelo elikhethiweyo. Imodyuli inokusebenza kwimo yejenereyitha (engaqeqeshekanga) apho i-10 MHz yangaphandle isuka kwiCesium.
okanye umgangatho weRubidium usetyenziswa njengereferensi yamaza. Oku kudala ikloko esekelwe kwi-PCI ezinzileyo kuyo yonke imisebenzi yexesha le-bc637PCI-V2.
I-bc637PCI-V2 isekela ngokuzenzekelayo zombini i-3.3 V kunye ne-5.0 V yokubonisa ibhasi ye-PCI. Udibaniso lwemodyuli lula lula ngabaqhubi abakhethiweyo beWindows okanye iLinux.

Ezi ntambo zinelebhile zinciphisa imfuno yokudala iintambo ezikhethekileyo ngexesha lophuhliso lweprojekthi kwaye ziqinisekise ukuba iimpawu zexesha ezichanekileyo ziyafikeleleka.
Kwiinkqubo ezidibeneyo zokuxhoma i-rack ezifuna ukufikelela lula kwiimpawu zexesha, iphaneli ye-patch ye-1U kunye ne-high-frequency signal breakout iveza yonke imiqondiso ekhoyo. Iphaneli ibonelela ngembonakalo ecwangcisiweyo neyobuchule kwi-I/O yexesha langaphandle lemisebenzi yekhadi le-PCI. Iphaneli ye-1U ihambelana ne-chassis eqhelekileyo okanye isiqingatha se-rack size. I-adapter ye-high-frequency breakout iveza umqondiso we-high-frequency signal kunye ne-DC yangaphandle yokulawula i-DAC kunye nomhlaba.
