Pakuyenda-kulondola kwambiri kwa satellite, kagwiridwe kake ka ma frequency source kumatsimikizira kulondola komanso kusasunthika kwa makina. Popeza BeiDou System (BDS) ikugwiritsidwa ntchito kwambiri m'mapulogalamu monga kuyendetsa galimoto, IoT, ndi kuyanjanitsa nthawi, kufunikira kwapamwamba-kumagwira ntchito, kutsika{3}}mphamvu{3}}magawo afupiafupi afupiafupi kukukulirakulira. The TT53H4-10.000-33NQDTN 10 MHz TCXO yochokera ku Suzhou Hangjing ndi njira yokhazikika yokhazikika nthawi yomwe idapangidwa ndendende kuti ikwaniritse izi.
Kufunika Kwambiri kwa Mapulogalamu a BeiDou
Mkati mwa cholandila cha BeiDou, kuyambira kumapeto kwa RF ndi m'badwo wa oscillator wamba kupita ku zitsanzo za baseband ndi kuyanjanitsa nthawi, wotchi yokhazikika yokhazikika ndiyofunikira. TT53H4 10 MHz TCXO imagwira ntchito yofunika kwambiri m'magawo otsatirawa:
Kupeza Siginecha Yokwezeka ndi Kutha Kutsata
Chipangizochi chimapereka kukhazikika kwafupipafupi:
Kukhazikika pafupipafupi:±0.5 ppm (–40 digiri mpaka +85 digiri)
Kulekerera Koyamba Kwambiri:± 1.0 ppm
Kulandila kwa ma sign a BeiDou, izi zimamasulira ku:
Kuchepetsa kulakwitsa kwafupipafupi
Masanjidwe osaka a Doppler
Liwiro lakupeza ma sigino a satana
2. Nayi kumasulira kwachingerezi kwa gawo lomwe mwapemphedwa, kusungitsa katswiri, boma, komanso kamvekedwe kachidule.
Kukhazikika Kwabwino Kwambiri ndi Kuthamanga Kwambiri
Zolakwika pafupipafupi mu TCXO zimamasulira kukhala zolakwika za nthawi, zomwe zimakhudzanso kuwerengera kwa pseudorange. TT53H4 imachepetsa kusonkhanitsa zolakwika zomwe zimachitika chifukwa cha kusintha kwa chilengedwe kudzera:
Kukhazikika kwa Voltage:± 0.2 ppm (Vcc ± 5%)
Kukhazikika kwa Katundu:± 0.2 ppm
Izi zimatsimikizira kuti ma terminals a BeiDou amakhalabe okhazikika ngakhale m'malo osinthika.
3.Low Phase Noise Design for Enhanced Ofooka Signal Performance
Chitsanzochi chimakhala ndi phokoso labwino kwambiri:
-97 dBc/Hz @ 10 Hz
-125 dBc/Hz @ 100 Hz
-145 dBc/Hz @ 1 kHz
-155 dBc/Hz @ 100 kHz
Ubwino:
Kupititsa patsogolo kutsata ma siginecha ofooka
Siginolo yolandirira bwino-mpaka-chiwerengero cha phokoso (SNR)
Kuchepetsa pang'ono zolakwika (BER)
Izi ndizofunikira makamaka m'malo ovuta monga ma canyons akumatauni ndi malo amkati.
4. Thandizo la BeiDou Timing ndi Holdover
Pazida zowerengera nthawi, zizindikiro za satellite zikatayika kwakanthawi, TCXO iyenera kusunga nthawi yakumaloko. TT53H4 imapereka:
Mlingo Wochepa Wokalamba:±1 ppm/chaka
Yambani Mwachangu-Mmwamba:5 ms
Izi zimawonetsetsa kuti makinawa azikhala ndi nthawi yokhazikika (monga 10 MHz + PPS) ngakhale pakatha-kutayika kwanthawi kochepa.
Mfundo Zazikulu Zazogulitsa
Basic Parameters
Nthawi zambiri:10.000 MHz
Mtundu Wotulutsa:Zithunzi za HCMOS
Supply Voltage: 3.3V
Kukula Kwa Phukusi:SMD 5.0 × 3.2 mm (kapangidwe kakang'ono)
Ubwino Wamagetsi Amagetsi
Ntchito Yozungulira:45% ~ 55% (mawonekedwe abwino kwambiri ofananira)
Nthawi Yokwera/Yogwa:6 ns (yogwirizana ndi-makina othamanga kwambiri a digito)
Kugwiritsa Ntchito Panopa:6 mA (zochepa{1}}mapangidwe amagetsi)
Wide Temperature Range & High Kudalirika
Kutentha kwa Ntchito:-40 digiri ~ +85 digiri
Woyenerera kudzera mu mayeso angapo odalirika:
>>Kutentha panjinga (1,000 cycle)
>>Kutentha kwakukulu ndi chinyezi (85 digiri / 85% RH)
>>Kugwedezeka / Dontho / ESD
Kuyenda pafupipafupi:Zonse zimasungidwa mkati mwa ± 1 ppm
III.Zochitika Zofananira za Ntchito
TT53H4-10.000-33NQDTN imagwiritsidwa ntchito kwambiri mu:
BeiDou / GNSS Receivers
Kuyenda pagalimoto
Malo ogwirira m'manja
Kuyika kwa Drone
Communication & Synchronization Zida
Maselo ang'onoang'ono a 5G
Ma seva olumikizana nthawi
Zida zowerengera nthawi pa intaneti
Mapulogalamu a Industrial & IoT
Smart grid
Machitidwe oyendetsera mafakitale
Kupeza zambiri-zolondola kwambiri
IV.Chifukwa Chiyani Sankhani TT53H4?
Poyerekeza ndi ma crystal oscillator (XO) ndi -okwera mtengo kwambiri a OCXOs, TT53H4 imakwanitsa kuchita bwino kwambiri ndi mtengo wake:
ppm-kukhazikika kwapamwamba kuti zikwaniritse zofunikira pa pulogalamu ya BeiDou
Mapangidwe a phokoso otsika kuti azigwira bwino ntchito m'malo ovuta
Kukula kocheperako + kugwiritsa ntchito mphamvu zochepa, koyenera pazida zophatikizidwa
Kudalirika kwakukulu kwa malo ogulitsa mafakitale
Mtengo wabwino kwambiri-kagwiridwe ka ntchito pa-kutumiza kwakukulu
V. Mapeto
Pamene BeiDou System ikupitilira kusinthika kukhala yolondola kwambiri, kugwiritsa ntchito mphamvu pang'ono, ndi miniaturization, TCXO yakhala malo oyambira pafupipafupi pazida zama terminal. TT53H4-10.000-33NQDTN, yokhala ndi kukhazikika kwafupipafupi, kachitidwe kaphokoso kakang'ono, ndi kudalirika kwakukulu, imapereka maziko olimba ndi odalirika a nthawi ya BeiDou navigation, kugwirizanitsa nthawi, ndi machitidwe olankhulana.
Sichiwongolero chabe-ndi "gwero la kugunda kwa mtima" lofunika kwambiri lomwe limatsimikizira kugwira ntchito kwadongosolo ndi bata.
