FPDLINK ibhazi rekufambisa rakasiyana-siyana rakagadzirwa neTI, rinonyanya kushandiswa kutumira data yemifananidzo, yakadai sekhamera uye data yekuratidzira.Iyo chiyero inogara ichishanduka, kubva kune yekutanga mitsetse inotumira 720P@60fps mifananidzo kune yazvino kugona kufambisa 1080P@60fps, iine machipi anotevera anotsigira kunyange yepamusoro-soro mifananidzo.Iyo yekufambisa kureba zvakare yakarebesa, inosvika kutenderera 20m, ichiita kuti ive yakakodzera kune mota application.

FPDLINK ine chiteshi chepamusoro-chekumberi chekufambisa data yemufananidzo wepamusoro uye chikamu chiduku chekutonga data.Kune zvakare yakaderera-inomhanya yekumashure chiteshi chekufambisa kwereverse control information.Iyo yekumberi nekumashure kutaurirana inoumba bi-directional control chiteshi, iyo inotungamira kune yakangwara dhizaini yeI2C muFPDLINK iyo ichakurukurwa mupepa rino.

FPDLINK inoshandiswa ne serializer uye deserializer yakabatanidzwa pamwe chete, CPU inogona kubatanidzwa kune serializer kana deserializer, zvichienderana nekushandiswa.Semuenzaniso, mune kamera application, kamera sensor inobatanidza kune serializer uye inotumira data kune deserializer, nepo CPU inogamuchira iyo data yakatumirwa kubva kune deserializer.Muchiratidziro chekuratidzira, iyo CPU inotumira data kune serializer uye iyo deserializer inogamuchira iyo data kubva kune serializer uye inotumira kune iyo LCD skrini kuti ionekwe.

Iyo CPU's i2c inogona kubva yabatanidzwa kune serializer kana deserializer's i2c.Iyo FPDLINK chip inogamuchira iyo I2C ruzivo inotumirwa neCPU uye inoendesa iyo I2C ruzivo kune rumwe rutivi kuburikidza neFPDLINK.Sezvatinoziva, mu i2c protocol, iyo SDA inowiriraniswa kuburikidza neSCL.Mumashandisirwo akajairika, data yakasungirirwa pamucheto unokwira weSCL, izvo zvinoda kuti tenzi kana muranda agadzirire data pamucheto unodonha weSCL.Zvisinei, muFPDLINK, sezvo FPDLINK kuendesa kune nguva, hapana dambudziko apo tenzi anotumira data, kazhinji muranda anogamuchira data maawa mashomanana gare gare kupfuura iyo tenzi anotumira, asi pane dambudziko apo muranda anopindura kuna tenzi. , semuenzaniso, apo muranda anopindura tenzi ne ACK apo ACK inotapurirwa kuna tenzi, yatove gare gare kupfuura nguva yakatumirwa nemuranda, kureva kuti yakatopfuura neFPDLINK kunonoka uye inogona kunge yakapotsa kusimuka. chikamu cheSCL.

Neraki, iyo i2c protocol inotora mamiriro aya.i2c inotsanangura pfuma inonzi i2c stretch, zvinoreva kuti i2c muranda anogona kudhonzera SCL pasi asati atumira ACK kana isati yagadzirira kuitira kuti tenzi anokundikana pakuedza kukwevera SCL kumusoro kuti tenzi arambe achiedza. dhonza SCL kumusoro uye umirire iyo, Naizvozvo kana uchiongorora iyo i2c waveform paFPDLINK Slave side, tichaona kuti nguva yega yega kero yemuranda chikamu inotumirwa, pane chete 8 bits, uye ACK ichapindurwa gare gare.

TI's FPDLINK chip inotora mukana wakazara wechinhu ichi, pane kungoendesa mberi yakagamuchirwa i2c waveform (kureva kuchengeta mwero webaud wakafanana neatumira), inotumirazve data yakagamuchirwa pachiyero chebaud chakaiswa paFPDLINK chip.Izvi zvakakosha kuti uzive kana uchiongorora iyo i2c waveform paFPDLINK Slave side.Iyo CPU i2c baud rate inogona kuita 400K, asi i2c baud rate paFPDLINK muranda wedivi i100K kana 1M, zvichienderana neSCL yakakwirira uye yakaderera marongero muFPDLINK chip.
