Chithunzi cha PCM1690
Chipangizo cha PCM1690 ndi chochita bwino kwambiri, chokhala ndi single-chip, 24-bit, njira eyiti, audio digito-to-analog converter (DAC) yokhala ndi zotuluka zosiyanasiyana.Njira zisanu ndi zitatu, 24-bit DAC imagwiritsa ntchito modulator yowonjezereka, yamitundu yambiri ya delta-sigma (ΔΣ) ndipo imathandizira 8-kHz mpaka 192-kHz miyeso ya zitsanzo ndi 16-/20-/24-/32-bit m'lifupi mwa digito. mawu olowera pamawu omvera.Mawonekedwe omvera a PCM1690 amathandizira mawonekedwe a nthawi-gawo-multiplexed (TDM) kuwonjezera pa muyezo I.2S, kulungamitsidwa kumanzere, kumanja, ndi mawonekedwe a DSP.
PCM1690 imatha kuwongoleredwa kudzera pamawaya atatu, mawonekedwe ogwirizana ndi SPI, kapena mawaya awiri.2C-compatible serial interface mu mapulogalamu, omwe amapereka mwayi wopezeka kuzinthu zonse kuphatikiza kutsitsa kwa digito, kusalankhula mofewa, kutsindika, ndi zina zotero.Komanso, mawonekedwe a hardware amapereka kagawo kakang'ono ka ntchito zogwiritsira ntchito pogwiritsa ntchito zikhomo ziwiri zowongolera.PCM1690 imapezeka mu 12-mm × 8-mm (12-mm × 6-mm thupi) HTSSOP-48 phukusi.
Pamaphukusi onse omwe alipo, onani chowonjezera chomwe chili kumapeto kwa pepala.
1. Kodi ogwira ntchito m'dipatimenti yanu ya R & D ndi ndani?Kodi ziyeneretso zanu ndi zotani?
-R & D Mtsogoleri: pangani dongosolo la nthawi yayitali la R & D ndikumvetsetsa momwe kafukufuku ndi chitukuko;Kuwongolera ndi kuyang'anira dipatimenti ya r&d kuti ikwaniritse njira zamakampani ndi mapulani apachaka a R&D;Kuwongolera kupita patsogolo kwa chitukuko cha mankhwala ndikusintha dongosolo;Khazikitsani gulu labwino kwambiri la kafukufuku wazinthu ndi chitukuko, kufufuza ndi kuphunzitsa ogwira ntchito zaukadaulo.
Woyang'anira R & D: pangani mankhwala atsopano a R & D ndikuwonetsa kuthekera kwa dongosolo;Kuyang'anira ndi kuyang'anira momwe ntchito ya R&d ikuyendera;Fufuzani zachitukuko chazinthu zatsopano ndikupereka mayankho ogwira mtima malinga ndi zomwe makasitomala amafuna m'magawo osiyanasiyana
Ogwira ntchito ndi R&d: sonkhanitsani ndikusankha zofunikira;Mapulogalamu apakompyuta;Kuyesa, kuyesa ndi kusanthula;Konzani zida ndi zida zoyeserera, zoyeserera ndi kusanthula;Lembani deta yoyezera, pangani mawerengedwe ndikukonzekera ma chart;Chitani kafukufuku wamawerengero
2. Kodi lingaliro lanu la kafukufuku ndi chitukuko ndi chiyani?
- Lingaliro lazinthu ndi kusankha kwazinthu ndikuwunika tanthauzo lazinthu ndi kapangidwe ka pulani ya projekiti ndi kuyezetsa kwachitukuko ndikutsimikizira kukhazikitsidwa kwa msika
