Samun abun ciki: Haɗa ta hanyar Wi{0}Fi zuwa shagunan sayar da littattafai na kan layi (gina{1}ciki ko na uku{2}} ƙungiya, kamar JD Read, WeChat Read, Kindle) don zazzagewa da daidaita ci gaban karatun.

Bayanan kula & Bayani: Yana ba da damar bayanin kula{0}} ɗauka, haskakawa, da bayanai ta hanyar stylus ko madannai.

Gudanar da Daftarin aiki: Mai da hankali kan karatun PDF, annotation, da sake kwarara; wasu tallafin duba daftarin aiki na Office (madaidaicin aiki / nazari).

Karin Bayanin App: Buɗe tsarin (misali, Android) ƙyale masu amfani su shigar da ƙa'idodin karatu na ɓangare na uku ko masu amfani.

III. Crystal Oscillators a cikin Akwatunan Littattafai na Lantarki: Fakitin, Mitoci, da Ƙayyadaddun bayanai

Wuraren littafai na lantarki, azaman hadaddun tsarin da aka haɗa, suna buƙatar mabambantan tushen agogo don samfura daban-daban. A ƙasa akwai ɓarna na ƙayyadaddun ƙayyadaddun ƙayyadaddun kristal oscillator:

IV. Me yasa waɗannan Crystal Oscillators suke da mahimmanci

Samar da Madaidaicin Lokacin "Zuciyar Zuciya"
Abubuwan haɗin dijital kamar na'urori masu sarrafawa, tsarin sadarwa, da musaya sun dogara da tsayayyen sigina na agogo don daidaita ayyuka. Idan ba tare da su ba, tsarin zai yi aiki ba daidai ba ko kuma yana aiki da kuskure.

Module Haɗuwa{0}}Takamaiman Bukatun

Ayyukan Processor: Maɗaukaki - mitoci, tsayayye na babban agogo (ta hanyar yawaita PLL) yana tabbatar da aikin CPU mai santsi.

Ingancin mara waya: Babban{0}} daidaito, ƙananan-lokaci - kristal amo (misali, 26/40MHz) suna da mahimmanci ga Wi{7}}Fi/BT transceivers, yana tasiri kai tsaye kwanciyar hankali, ƙimar bayanai, da ingancin sigina.

Tsare lokaci: kristal RTC 32.768kHz yana kiyaye ingantaccen lokaci tare da ƙaramin ƙarfi{1}, koda lokacin yanayin bacci.

Haɗin kai Aiki: Samfuran taɓawa, wartsakewa nuni, da sake kunnawa mai jiwuwa kowane yana buƙatar agogon sadaukarwa don daidaita ayyukan.
