Sharaxaada Alaabta
Soo koobida alaabta
SR812ST-R waa heerkeena ugu dambeeyay ee laba-soo-saarka shabakada CATV soo-dhoweeyaha indhaha. Cod-weyneeye ka hor wuxuu qaataa-GaAs MMIC oo buuxa, cod-sameeyaha dambe wuxuu qaataa moduleka GaAs. Nakhshad wareeg ah oo la hagaajiyay oo ay weheliso 15 sano ee waayo-aragnimada naqshadaynta xirfadeed, waxay ka dhigtaa qalabku inuu gaaro tusmooyinka waxqabadka wanaagsan. Xakamaynta Microprocessor, soo bandhigida dhijitaalka ah ee cabirrada, khaladka injineernimada ayaa si gaar ah u fudud. Waa qalabka ugu muhiimsan ee lagu dhisayo shabakada CATV.
Tilmaamaha Waxqabadka
- Jawaab sare tuubada beddelka sawir-qaadaha PIN.
- Naqshad wareeg ah oo la wanaajiyey, wax soo saarka habka SMT, iyo dariiqa calaamadaha la hagaajiyay ayaa ka dhigaya gudbinta signalka sawir-qaadista mid siman.
- Chip attenuation RF gaar ah, oo leh feejignaan RF wanaagsan iyo toosan siman, saxsanaan sare.
- Qalabka cod-weyneeye ee GaAs, soo-saarka korontadu laba-laabanto, oo leh faa'iido sare iyo qallooc hoose.
- Hal Chip Microcomputer (SCM) qalabka kontoroolka shaqada, LCD waxay soo bandhigtaa cabbirada, ku habboonaanta iyo hawlgalka dareenka leh, iyo waxqabadka xasilloon.
- Waxqabadka AGC heer sare ah, marka cabbirka awoodda indhaha ee wax gelinta uu yahay -9 ～＋2dBm, heerka wax soo saarku isma beddelo, iyo CTB iyo CSO asal ahaan isma beddelaan.
- Interface isgaadhsiinta xogta kaydsan, waxay ku xidhmi kartaa fasalka Ⅱ maamulka shabakada jawaabaha, oo marin kara nidaamka maaraynta shabakada.
Soo-celinta soo-celinta waxay dooran kartaa qaabka dillaaca si uu si xooggan u yareeyo isku-dhafka dhawaaqa oo loo yareeyo lambarka hore ee qaataha.
