32.768kHz n-gun rawng ai n-gun rawng ai jak ni hpe jai lang ai lam hpe sawk sagawn ai
32.768kHz crystal oscillators ni hpe grai hkrak ai, n-gun n law ai, ngang grin ai frequency arawn alai ni a majaw aten masat masa (sh) n-gun n law ai ahkying hpe ra ai electronic jak ni hta grai lang ma ai. Lahta na lam ni gaw, laksan jai lang ai lam ni hpe sawk sagawn ai lam nkau mi rai nga ai:
1. Tengman ai-Aten Hkying (RTC) Module
Laika shawk shawn ai lam ni:
Smart meter, IoT jak, server motherboard, mawdaw jak ni zawn re ai jak ni hpe aten ka matsing nna, shingdaw ai lam galaw ai.
Bungli byin ai:
32.768kHz gaw RTC module ni a matu masat da ai nsen re. Frequency garan ngut ai hpang (15-stage binary garan ai hku nna: 215=32768), dai gaw 1Hz hkrak rai nna, lahkawng ngu na pulse signal hpe hkrak sha shachyut lu ai.
Mabyin masa ni:
Smart watch: Aten hpe madun ai hpe n-gun n law ai- masa hta tawn da ai; main CPU gaw sleep mode kaw nga ai shaloi RTC sha bungli galaw ai.
Server motherboard: Mabyin masa ni a matu aten masat ni hpe ka matsing da ai; wan n-gun yawm mat ai hpang mung, coin cell battery hku nna aten hpe hkan sa ya ai.
2. N-gun n law ai-MCU System ni
Laika shawk shawn ai lam ni:
Battery- hte galaw ai jak ni (ga shadawn, sensor node ni, wire n lang ai tsan tsan kaw na hkang ai jak ni).
Bungli byin ai:
Standby mode hta n-gun jai lang ai lam hpe shayawm na matu Microcontroller (MCUs) ni a matu n-gun n law ai-lawan ai ahkying source langai hku nna magam gun ai. Ga shadawn, STM32 series MCU ni a LSE (N-gun n law ai-Speed Shinggan Ahkying) masa hpe lang ai.
Mabyin masa ni:
Katsi ai hte katsi ai sensor: Data ni hpe shinggyin la na matu minit 10 shagu rawt ai; 32.768kHz crystal oscillator hpe kam hpa nna ngam ai aten hpe aten masat ya ai, μA madang daram sha n-gun jai lang ai.
3. Jai lang ai Electronic arung arai ni
Laika shawk shawn ai lam ni:
Mobile phone, tablet, digital camera zawn re ai ni hpe lang ai.
Bungli byin ai:
Madung crystal oscillator hpe pat kau ai aten hta pyi, madung aten masat masa galaw ai lam ni hpe galaw lu na matu, madung system a matu karum shingtau ahkying hpe jaw ya ai.
Mabyin masa ni:
Smartphone: Hkring mat ai hpang aten hpe n-gun jaw ya ai; power on galaw ai shaloi aten hpe reset galaw ra na n re.
4. Mawdaw hte seng ai Electronics
Laika shawk shawn ai lam ni:
-mawdaw kata na infotainment system ni, jak rung ni, ECU ni (Engine hpe hkang ai jak ni) ni hta lang ai.
Bungli byin ai:
Mabyin masa ni hpe ka matsing na matu hte mara hpe sawk sagawn na matu aten masat masa hku nna lang ai, shing nrai CAN bus matut mahkai lam a matu karum ai ahkying aten hku nna lang ai.
Mabyin masa ni:
Driving recorder: Accident byin ai aten hpe hkrak hkrak ka matsing da ai (±20ppm laman hta shut ai lam nga ai).
5. Tsi mawan ni
Laika shawk shawn ai lam ni:
Hkamja lam hte seng ai tsi mawan ni (ga shadawn, sai hta na glucose meter, myit masin hpe yu ai jak ni).
Bungli byin ai:
Device gaw aten kadun laman hta data ni hpe shinggyin la lu ai (sh) low-power mode hta pyi alarm ni hpe shabyin ya lu ai hpe kam shangun ai.
Mabyin masa ni:
Myit masin n-gun shayawm ai jak: 32.768kHz crystal oscillator a ngang grin ai lam hpe kam hpa nna, myit masin n-gun shayawm ai lam hpe hkrak hkra galaw lu ai.
6. Hpaga lam hpe hkang zing ai lam
Laika shawk shawn ai lam ni:
PLCs (Program galaw mai ai Logic hpe hkang ai), hpaga lam hta galaw ai sensor ni.
Bungli byin ai:
Device law law a aten hpe synchronize galaw ai (sh) operation log ni hpe ka matsing da ai.
Mabyin masa ni:
Automated galaw ai line: Sensor law law gaw 32.768kHz ahkying hku nna data upload aten hpe shingdaw ya ai.
7. Design hpe myit yu ra ai lam ni
Load Capacitance hpe shingdaw ai lam: Shinggan na n-gun (galaw madang 6~12pF) hpe crystal oscillator a masat da ai hte maren gram lajang na; n rai yang, frequency n bung ai lam byin chye ai.
PCB a hkrang: Crystal oscillator hpe IC hte mai byin ai daram ni htep hkra tawn da na; n-gun kadun ai hpe lang nna, -frequency signal n-gun kaba ai hpe koi nga u.
Hka lum ai lam hta hkra machyi ai lam: Hka lum ai lam hpe galu kaba hkra galaw na matu (-40℃~85℃), grai hkrak ai kristal oscillator (ga shadawn, ±5ppm) hpe lata la u.
8. Masha law malawng hkrum katut ai lam ni
Oscillate n lu galaw ai: Capacitance n htap htuk ai majaw, crystal oscillator hkrat sum ai majaw, PCB n san seng ai majaw rai na re.
Frequency n bung ai lam: Load n-gun (sh) crystal oscillator a asak kaba wa ai hpe jep yu u.
32.768kHz crystal oscillators ni hpe rational hku jai lang ai hku nna, jak ni a kam hpa mai ai lam hte n-gun atsam jai lang ai lam hpe grai kaja hkra galaw lu na re.
