Tsanangudzo yePCM1690
Iyo PCM1690 mudziyo ndeyepamusoro-inoshanda, single-chip, 24-bit, sere-channel, audio digital-to-analog converter (DAC) ine zvinobuda zvakasiyana.Iyo sere-channel, 24-bit DAC inoshandisa yakagadziridzwa, yakawanda-level delta-sigma (ΔΣ) modulator uye inotsigira 8-kHz kusvika 192-kHz sampling rates uye 16-/20-/24-/32-bit upamhi hwedhijitari. izwi rekuisa redhiyo pane odhiyo interface.Iyo yekuteerera interface yePCM1690 inotsigira iyo nguva-division-multiplexed (TDM) fomati kuwedzera kune yakajairwa I.2S, kuruboshwe-kururamiswa, kurudyi-kururamiswa, uye DSP mafomati.
Iyo PCM1690 inogona kudzorwa kuburikidza ne-tatu-waya, SPI-inoenderana interface, kana maviri-waya, I.2C-inoenderana serial interface musoftware, iyo inopa mukana kune ese mabasa anosanganisira dhijitari attenuation, zvinyoro zvinyoro, de-kusimbisa, zvichingodaro.Zvakare, Hardware control mode inopa subset yemushandisi-inorongwa mabasa kuburikidza maviri ekudzora mapini.Iyo PCM1690 inowanikwa mune 12-mm × 8-mm (12-mm × 6-mm muviri) HTSSOP-48 package.
Kune ese mapakeji aripo, ona iyo inorongeka yekuwedzera pakupera kwedata sheet.
1. Ndivanaani vashandi mudhipatimendi rako reR & D?Ndezvipi zvidzidzo zvako?
-R & D Mutungamiriri: gadzira chirongwa chekambani chenguva refu R & D uye ubate gwara rekutsvaga nekusimudzira;Tungamira uye tarisa r&d dhipatimendi kuti iite kambani r&d zano uye yegore R&D chirongwa;Dzora kufambira mberi kwekugadzirwa kwechigadzirwa uye gadzirisa chirongwa;Gadzira yakanakisa chigadzirwa chekutsvagisa uye timu yekusimudzira, yekuongorora uye yekudzidziswa ine chekuita nehunyanzvi vashandi.
R & D Maneja: gadzira chigadzirwa chitsva R & D kuronga uye kuratidza kugona kwechirongwa;Tarisa uye gadzirisa kufambira mberi uye kunaka kwer&d basa;Tsvagurudza kugadzirwa kwechigadzirwa chitsva uye kurudzira mhinduro dzinoshanda zvinoenderana nezvinodiwa nevatengi munzvimbo dzakasiyana
Vashandi veR&d: unganidza uye gadzirisa data rakakosha;Computer programming;Kuita zviedzo, bvunzo uye ongororo;Gadzirira zvinhu uye zvishandiso zvekuyedza, bvunzo uye ongororo;Rekodha data yekuyera, ita kuverenga uye gadzira machati;Ita ongororo dzenhamba
2. Ndeipi yako chigadzirwa tsvakurudzo uye budiriro pfungwa?
-Kufunga kwechigadzirwa uye sarudzo yechigadzirwa pfungwa uye yekuongorora tsanangudzo yechigadzirwa uye dhizaini dhizaini uye kusimudzira chigadzirwa kuyedzwa uye kusimbiswa kwekutanga kumusika.
