Munyika yemagetsi, kuve nechaizvo zvikamu zvakakosha kuti uve nechokwadi chekushanda kwakanaka kwechero dunhu. Chimwe chezvinhu zvakakosha kuita izvi ndeye oscillating makristasi uye ceramic resonators, kunyanya avo vane kuwanda kwe 16 MHz, senge yakakurumbira HC-49S package kana iyo CSTCE16M0V53 ceramic resonator. Kunyangwe iwo achigona kutaridzika akafanana pakutanga pakuona, imwe neimwe inoita chaiwo mabasa anoita kuti akwanise kune akasiyana maapplication.
Kuziva mutsauko pakati pezvikamu izvi uye kunzwisisa mashandisiro azvinoita kunogona kuve kiyi yekusarudza iyo yakakodzera yemagetsi mapurojekiti ako. Muchikamu chino, tichaenda pamusoro pezvinhu zvose zvakakosha pamusoro pezvikamu. HC-49S piezoelectric makristasi uye muenzaniso CSTCE16M0V53, kubva kune ayo maficha kusvika kune ayo anonyanya kushandiswa mumidziyo yemazuva ano.
Chii chinonzi crystal oscillator uye chinoshanda sei?
Un crystal oscillator yakavakirwa pa mechanical resonance Chinhu chepiezoelectric, kazhinji quartz, chinoshandiswa kugadzira chiratidzo chemagetsi cheiyo frequency chaiyo. Chiitiko ichi chinoitika apo kristaro inodedera pakugamuchira kuchaji kwemagetsi, ichigadzira frequency yakagadzikana inogona kushandiswa sewachi kana chiratidzo chenguva mumaseketi edhijitari. Kuti uwedzere ruzivo rwako rwekuyedza uye kuona izvi zvikamu, unogona kubvunza gwara redu pa nzira yekuedza zvinhu zvemagetsi.
Muenzaniso HC-49S Ndiyo imwe yemapakeji akajairika kune aya makristasi. Iyo ine mapini maviri, inoshanda yakatevedzana kuramba inosvika makumi matatu ohms, a kushanda frequency ye16 MHz nekushivirira kwe +/- 20 ppm uye kugona kuri pedyo ne20 pF. Huremu hwayo hwakatenderedza 2 magiramu, ichiita kuti ive yakakodzera kune zvishandiso zvisina zvakakomba saizi zvinorambidzwa.
Ceramic resonators: imwe nzira yakasiyana-siyana
Pamberi pegirazi reHC-49S, isu tinowanawo iyo ceramic resonators s CSTCE16M0V53-R0, muenzaniso unopa maitiro akafanana, asi nenzira yakasiyana. Ichi chikamu chinokosheswa zvakanyanya nekuda kwekugona kwacho gadzira yakagadzikana frequency oscillation kuburikidza nekudengenyeka kweceramic material panzvimbo yequartz. Muchinyorwa Mhando dzeMEMS oscillators uye nezvimwe iwe unogona kunyura zvakadzika mukati mayo akasiyana matekinoroji.
Aya maresonators anoshandiswa nguva, frequency control uye chiratidzo chekugadzirisa mune zvakasiyana-siyana zvezvigadzirwa zvemagetsi. Kushandiswa kwayo kwakajairika muzvikamu zvakaita semagetsi evatengi, mota, uye kunyange microcontroller-based embedded system.
Mhando dze16 MHz ceramic resonators
Iwo akasiyana eceramic resonators anowanikwa pamusika anovhara zvakasiyana siyana zvinodiwa. Mamwe emhando dzakajairika anosanganisira:
- Standard model: Yakakwana kune zvakajairwa zvikumbiro apo kurongeka kwakanyanya kusingakoshi.
- Tembiricha yakabhadharwa resonators: Ivo vanochengetedza kugadzikana kwefrequency kunyangwe pasi pekuchinja kwakakosha kwekupisa, kwakanakira maindasitiri kana nharaunda dzemotokari.
- Low profile modhi: Yakagadzirirwa midziyo ine muviri nzvimbo inogumira.
- High frequency variants: Kunyangwe chiyero chiri 16 MHz, kune zvakare sarudzo dzinobvumidza yakakwirira ma frequency kune chaiwo zvinodiwa.
Misiyano yakakosha pakati peHC-49S uye CSTCE16M0V53 girazi
Kunyangwe zvese zviri zviviri zvikamu zvinoshanda kugadzira chaiwo ma frequency, pane inocherekedza misiyano yehunyanzvi pakati pe HC-49S kristaro and the Ceramic resonator CSTCE16M0V53:
- Material: Iyo HC-49S inoshandisa quartz, nepo CSTCE16M0V53 iri ceramic-yakavakirwa.
