Mai karamin SiTime mai sauƙi na MEMS yana haɓaka daidaitattun 5ppb don haɓaka 5G

Na'urori suna dogara ne akan sassan 100ppb da aka saki a cikin shekaru biyu da suka gabata kuma, duk da haka ciki har da tanda, auna 7 x 9 x 6.5mm.

Kamfanin yana amfani da samfurin lokaci a cikin kayayyakin 5G, inda za a yada yawancin ƙananan wurare a fadin wuri, a wurare marasa tsaro idan aka kwatanta da tushen 3G ko 4G - a kan ginshiƙai, alal misali, wanda za a fallasa zuwa karin vibration da thermal bambancin.

"Za mu iya cimma ± 50ppt / ° C maɓallin mita mita, wanda shine 10x mafi alhẽri fiye da kowane mabudin OCXO mun gani," SiTime v-p na tallan kamfanin Piyush Sevalia ya shaida wa Electronics Weekly. "Tsayayyar bidiyo shine ± 0.1ppb / g, sau 10-20 fiye da ma'adini da muka gani."

Tare da wannan matakin kare kariya, a cewar Sevalia, ana iya sanya oscillator kusan a ko'ina cikin PCB, kuma babu buƙatar ƙara yawan wanda ya dace da iska - magoya bayan kunnawa da aka sani sun tsara yawan ƙaddamar da na'urori na OCXOs, ya ya ce, kara da cewa yawancin zafin jiki yana saukowa zuwa tanderun da aka tanada da kuma diyya. Allan kuskure ne 2e^-11 karkashin iska

Tsayayyar juyawa suna saukowa zuwa masallacin minuscule na resonator silicon. "Yaduwar makamashi da ma'aurata suke ciki ƙananan," in ji Sevalia.

Ƙara wutar ta ƙara yawan amfani da wutar lantarki, zuwa 650mA idan aka kwatanta da 40mA ta farkon 100ppb wanda ba a cikin tanda ba, wanda ya fi ƙasa a 5 x 3.2mm.

Hanyar da aka kulle lokaci-lokaci yana nufin mita fitarwa yana iya canzawa kuma za'a iya shirya shi a fadin 1-60MHz ko 60-220MHz dangane da bambancin.

Ana gudanar da aiki tsakanin -40 zuwa + 85 ° C, tare da -40 zuwa + 95 ° C da -40 zuwa + 105 ° C a cikin bututun mai.

Umurni na kan wutar lantarki na samar da wutar lantarki yana ƙaruwa da rinjayen tasirin jiragen ruwa, kuma yana kawar da buƙatar ƙirar waje, zuwa wani adadi wanda ba a saki ba a lokacin rubutawa. "Muna fatan za mu kasance mai kyau, tun da yake muna amfani da irin kayan gine-gine na zamani da fasahohin kamar yadda aka saba da su a yau," in ji Sevalia.

Zaɓuɓɓukan fitowa sune LVCMOS ko zane-zane.

Siffofin don telecoms za su kasance samuwa gamuwa Stratum 3E tabarau, wanda ya hada da:

• Tsararren kyauta mai shekaru 20 na +/- 4.6 ppm
• 24 hours riƙeover na ± 10ppb hada da zazzabi effects
• 1 ppb / day (a ± 5 ° C) shawarwarin

An kirkiro fasahar da aka yi amfani da shi a cikin 'Emerald Platform'.

Ana samo samfurori na Emerald a yanzu don abokan ciniki mai cin gashin kanta, tare da yawan kayan da aka shirya su a Q2 2019.
