Fa'amatalaga mo le PCM1690
O le masini PCM1690 o se faʻaogaina maualuga, tasi-chip, 24-bit, valu-channel, leo numera-i-analog converter (DAC) faʻatasi ai ma gaioiga eseese.O le valu-auala, 24-bit DAC faʻaaogaina se faʻaleleia atili, tele-level delta-sigma (ΔΣ) modulator ma lagolagoina le 8-kHz i le 192-kHz sampling rates ma le 16-/20-/24-/32-bit lautele numera numera. upu fa'aoga leo i luga ole fa'aoga leo.O le faʻalogo leo o le PCM1690 e lagolagoina le faʻasologa o taimi-vaega-faʻatele (TDM) faʻaopoopo i le tulaga I.2S, agavale-tautonu, sa'o-tautonu, ma DSP faatulagaga.
O le PCM1690 e mafai ona pulea e ala ile tolu-uaea, fesoʻotaʻiga SPI, poʻo le lua-uaea, I.2C-compatible serial interface i software, lea e maua ai le avanoa i galuega uma e aofia ai le attenuation numera, mute malu, de-fa'amamafa, ma isi.E le gata i lea, o le faʻaogaina o meafaigaluega e maua ai se vaega o galuega e mafai ona faʻaogaina e le tagata e ala i pine e lua.Ole PCM1690 o lo'o maua ile 12-mm × 8-mm (12-mm × 6-mm tino) HTSSOP-48 afifi.
Mo afifi uma o lo'o avanoa, va'ai le fa'aopoopo fa'atonu i le pito o le pepa fa'amatalaga.
1. O ai le aufaigaluega i lau matagaluega R & D?O a ou agavaa?
-R & D Fa'atonu: fa'atulagaina le fuafuaga a le kamupani mo se taimi umi R & D ma malamalama i le itu o su'esu'ega ma atina'e;Ta'ita'i ma va'ava'ava'a matagaluega e fa'atino fuafuaga fa'ata'ita'i a le kamupani ma fuafuaga tau su'esu'ega fa'aletausaga;Pulea le alualu i luma o le atinaʻeina o oloa ma fetuunai le fuafuaga;Fa'atu au su'esu'e ma atina'e oloa lelei, su'etusi ma a'oa'oga tagata faigaluega fa'apitoa.
Pule o le R & D: faia ni oloa fou R&D fuafuaga ma fa'aalia le fa'atinoina o le fuafuaga;Vaavaaia ma pulea le alualu i luma ma le tulaga lelei o galuega su'esu'e;Su'esu'e le atina'eina o oloa fou ma tu'uina atu ni fofo lelei e tusa ai ma manaoga o tagata fa'atau i vaega eseese
Aufaigaluega R&d: aoina ma fa'avasega fa'amaumauga autu;Polokalame faakomepiuta;Fa'atinoina o su'ega, su'ega ma au'ili'ili;Saunia meafaitino ma meafaigaluega mo suʻega, suʻega ma suʻesuʻega;Fa'amaumau fa'amaumauga o fua, fai fa'atatau ma saunia siata;Faia su'esu'ega fuainumera
2. O le a lau su'esu'ega oloa ma manatu atina'e?
- Fuafuaga o oloa ma filifiliga manatu o oloa ma iloiloga fa'amatalaga o oloa ma fa'ata'ita'iga o fuafuaga fa'atino ma atina'e fa'ata'ita'iga o oloa ma fa'amaonia fa'alauiloa ile maketi
