LINEAR TECHNOLOGY LTC6909 3 i le 8 Output Multiphase Oscillator ma SSFM
FAAMATALAGA
Fa'aaliga fa'ata'ita'iga 1446 o lo'o fa'aalia ai le LTC6909 multi-ple output oscillator fa'atasi ai ma le fa'avasegaina o alaleo fa'asolosolo (SSFM). O le LTC®6909 o se fa'aoga sa'o sa'o oscillator faigofie e mafai ona tu'uina atu 1-, 2-, 3-, 4-, 5-, 6-, 7- po'o le 8-vase fa'atasi galuega. O le LTC6909 fa'asalalau fa'asologa o alaleo (SSFM), e mafai ona fa'aagaina e fa'aleleia le fa'aogaina o feso'ota'iga eletise (EMC). E valu galuega eseese e maua ai e oo atu i le valu rail-to-rail, 50% ti'eti'e fa'ailoga uati. I le faʻaaogaina o mea faʻaoga e tolu, o galuega faatino e faʻatulagaina mo le vaeluaga o vaega, mai le 45 ° i le 120 ° (tolu i le valu vaega). E mafai fo'i ona fa'amaualalo pe fa'atutu mo le Hi-Z le fa'atinoina o le uati. O se tasi tetee (RSET) faʻatasi ma le faʻatulagaina o vaega, faʻatulagaina le faʻasologa o galuega, faʻavae i luga o le fua faʻatatau:
fOUT = (20MHz x 10k)/(RSET x PH)
lea PH = 3, 4, 5, 6, 7 po o le 8
ole fOUT laina ole 12.5kHz i le 6.67MHz.
O le PH0, PH1 ma le PH2 logic inputs o loʻo faʻamalamalamaina le LTC6909 multi-phase mode of operation ma pulea ana galuega faatino e pei ona taua i lalo:
PH2 PH1 PH0 FAIGA
0 0 0 O Galuega Fa'atino uma o lo'o Opeopea (Hi-Z)
0 0 1 O Galuega Fa'atino uma o lo'o Fa'amaulalo
0 1 0 3-Vaega Tulaga (PH = 3)
0 1 1 4-Vaega Tulaga (PH = 4)
1 0 0 5-Vaega Tulaga (PH = 5)

1 1 0 7-Vaega Tulaga (PH = 7)
1 1 1 8-Vaega Tulaga (PH = 8)
O le DC1446 o lo'o i ai se LTC6909 ma fa'amaufa'ailoga mo su'ega e valu. I luga o le laupapa osooso ua saunia e seti le LTC6909 vaega vaega (PH0, PH1 ma PH2) ma le SSFM modulation. O le fa'asologa o taimi fa'apipi'i i luga o le laupapa (RSET) o lo'o fa'apipi'iina muamua i le 100k luga o le mauga re-sistor (fa'aopoopo, e lua pine fa'amau e tu'uina atu mo le fa'aogaina o le RSET fa'aulu).
Fuafuaga files mo lenei laupapa matagaluega o loʻo avanoa.
Valaau le fale gaosi LTC. LTC, LT o fa'ailoga fa'ailoga a le Linear Technology Corporation.
Vave Amata Taualumaga
Fa'ata'ita'iga circuit 1446 e faigofie ona fa'atutu ma fa'ata'ita'i. Va'ai i le Ata 1 mo le seti su'ega vave ma mulimuli i le fa'agasologa o lo'o i lalo:
- Tuu tagata osooso i tulaga nei:
JP3 (PH0) i le V+, JP4 (PH1) i le V+, JP1 (PH2) i le V+ ma le JP1 (MOD) i le SSFM OFF. - 2. Seti le eletise i le 5V.
- Ki le sapalai eletise.
- Faatasi ai ma se su'esu'ega 10x e feso'ota'i ma OUT1 e tatau ona fa'aalia e le oscilloscope se 5V, 250kHz, sikuea faatafafa (±4.5%).
FA'ATA'U AMATA VAIVAI 
FAAMANATU: O galuega faatino e 6909 (OUT1-OUT8) e mafai ona ave le 1k ma le 50pF uta. Afai e fa'aogaina se su'esu'ega o alaleo e fua ai le fa'asalalauina o alaleo fa'asalalau ona fa'aoga lea o se su'esu'ega maualuga e mata'ituina ai galuega faatino (e masani lava o le fa'aogaina o le fa'aoga ole alaleo ole 50 ohms).
