Taw qhia

Lub koob yees duab hauv smartphones yog MIPI, thiab qee lub koob yees duab (xws li qee yam khoom siv uas txhawb nqa DVP interface) yog DVP.

MIPI yog luv luv rau Mobile Industry Processor Interface (In luv luv, USB stands rau Universal Serial Bus, MIPI stands rau Mobile Industry Processor Interface, DVP stands for digital video port, thiab CSI stands for CMOS Sensor Interface.

 

1.DVP interface

DVP

DVP tsheb npav PCLK txwv txog li 96M, thiab qhov ntev ntawm txoj kab tsis tuaj yeem ntev dhau, qhov siab tshaj plaws ntawm tag nrho DVP yog qhov zoo tshaj plaws tswj hauv qab 72M, PCB layout yooj yim rau kos

DVP yog qhov chaw nres nkoj sib npaug thiab xav tau PCLK, VSYNC, HSYNC, D[0:11] - tuaj yeem yog 8/10/12-ntsis cov ntaub ntawv, nyob ntawm ISP lossis baseband kev txhawb nqa

DVP tso zis ib feem: VSYNC (thav duab sync teeb liab), HSYNC (kab sync teeb liab), PCLK (pixel moos), cov ntaub ntawv kab (8-ntsis lossis 10-ntsis) - thawj RGB cov ntaub ntawv xa mus

MIPI yog qhov sib txawv ntawm qhov chaw nres nkoj sib kis, nrawm nrawm, tiv thaiv kev cuam tshuam.Mainstream xov tooj ntawm tes modules tam sim no siv MIPI kis tau tus mob.

MIPI lub koob yees duab muaj peb lub zog siv: VDDIO (IO lub zog), AVDD (analog zog), DVDD (kernel digital zog), sib txawv sensor module lub koob yees duab fais fab mov txawv, AVDD muaj 2.8V lossis 3.3V;DVDD feem ntau siv 1.5V lossis siab dua, cov tuam txhab tsim qauv sib txawv.

Cov lus ceeb toom ntxiv: MIPI lub koob yees duab interface hu ua CSI, thiab MIPI zaub interface hu ua DSI.

CSI-2 interface specification yog tso tawm los ntawm MIPI (Mobile Industry Processor Interface) Alliance lub koom haum ntawm lub koob yees duab serial interface.

MIPI CSI-2 interface siv tsawg dua cov peev txheej los ntawm CPU - ua tsaug rau nws cov txheej txheem ntau yam.Nws yog lub koob yees duab default interface rau Raspberry Pi thiab Jetson Nano.Raspberry Pi lub koob yees duab module V1 thiab V2 kuj yog raws li nws.

MIPI yog tus qauv qhib rau cov ntawv thov mobile processors pib los ntawm MIPI Alliance, thiab MIPI-CSI-2 raws tu qauv yog sub-protocol ntawm MIPI Alliance raws tu qauv, uas yog tsim tshwj xeeb rau lub interface ntawm lub koob yees duab nti.

 

Ronghua, yog cov chaw tsim khoom tshwj xeeb hauv R & D, kev kho kom haum, tsim khoom, muag thiab kev pabcuam ntawm lub koob yees duab modules, USB DVP

thiab MIPI lub koob yees duab modules, lo ntsiab muag thiab lwm yam khoom.Yog xav tiv tauj peb, thov:
