HDMI Intel FPGA IP Izikhokelo zoYilo
I-HDMI Intel FPGA i-interface ine-Transition Minimized Differential Differential (TMDS) idatha kunye neendlela zewashi. I-interface iphinda ithwale i-Video Electronics Standards Association (i-VESA) i-Display Data Channel (DDC). Amajelo e-TMDS aphatha ividiyo, iaudio, kunye nedatha encedisayo. I-DDC isekwe kwiprothokholi ye-I2C. I-HDMI ye-Intel FPGA IP core isebenzisa i-DDC ukufunda iDatha yeSazisi eyongeziweyo (EDID) kunye nokutshintshwa koqwalaselo kunye nolwazi lwesimo phakathi komthombo we-HDMI kunye ne-sink.
I-HDMI Intel FPGA IP yeengcebiso zoYilo lweBhodi
Xa uyila inkqubo yakho ye-IP ye-Intel FPGA IP, qwalasela la macebiso alandelayo oyilo lwebhodi.
- Ungasebenzisi ngaphezulu kweendlela ezimbini ngomkhondo kwaye uphephe ngokusebenzisa izibonda
- Tshatisa iperidi yokwahlulahlula kwi-impedance yesiqhagamshelo kunye nendibano yentambo (100 ohm ±10%)
- Ukunciphisa i-inter-pair kunye ne-intra-pair skew ukuhlangabezana nemfuno ye-TMDS ye-skew yesignali
- Kuphephe ukujongisa izibini ezahlukeneyo phezu komsantsa kwinqwelomoya engaphantsi
- Sebenzisa iindlela zoyilo zePCB ezinesantya esiphezulu
- Sebenzisa i-level shifters ukuhlangabezana nokuthotyelwa kombane kuzo zombini i-TX kunye ne-RX
- Sebenzisa iintambo ezomeleleyo, njenge-Cat2 cable ye-HDMI 2.0
Imizobo yeSchematic
I-Bitec schematic diagrams kumakhonkco anikiweyo abonisa i-topology yeebhodi zophuhliso ze-Intel FPGA. Ukusebenzisa i-HDMI 2.0 link topology ifuna ukuba uhlangabezane ne-3.3 V yokuthotyelwa kombane. Ukuhlangabezana nokuthotyelwa kwe-3.3 V kwizixhobo ze-Intel FPGA, kufuneka usebenzise i-level shifter. Sebenzisa i-DC-coupled redriver okanye i-retimer njenge-level shifter ye-transmitter kunye nomamkeli.
Izixhobo zomthengisi zangaphandle ziyi-TMDS181 kunye ne-TDP158RSBT, zombini zisebenza kwii-DCcoupled links. Udinga ukutsalwa okufanelekileyo kwimigca yeCEC ukuze uqinisekise ukusebenza xa usebenzisana nezinye izixhobo zolawulo olukude lwabathengi. I-Bitec schematic diagrams are CTS-certified. Isiqinisekiso, nangona kunjalo, sithe ngqo kwinqanaba lemveliso. Abaqulunqi beqonga bayacetyiswa ukuba baqinisekise imveliso yokugqibela yokusebenza ngokufanelekileyo.

I-Hot-Plug Detect (HPD)
Isiginali ye-HPD ixhomekeke kwisignali yaMandla engenayo + 5V, ngokomzekeloampNoko ke, i-pin ye-HPD inokuqinisekiswa kuphela xa i-+5V yesiginali yaMandla evela kumthombo ibhaqwe. Ukujongana neFPGA, kufuneka uguqulele uphawu lwe 5V HPD kwi FPGA I/O vol.tage level (VCCIO), usebenzisa i-voltagUmguquli we-e onjenge-TI TXB0102, engenazo i-resistors zokutsalela phezulu ezidibeneyo. Umthombo we-HDMI kufuneka uhlise isiginali ye-HPD ukuze ikwazi ukwahlula ngokuthembekileyo phakathi kwesiginali ye-HDD edadayo kunye nevolthi ephezulu.tage kwinqanaba HPD uphawu. I-HDMI isinki +5V isignali yamandla kufuneka iguqulelwe kwi-FPGA I/O voltage level (VCCIO). Isiginali kufuneka itsalwe buthathaka kunye ne-resistor (10K) ukwahlula isignali edadayo +5V yamandla xa ingaqhutywa ngumthombo we-HDMI. Umthombo we-HDMI +5V isignali yamandla inokhuseleko lwangoku olungekho ngaphezu kwe-0.5A.
HDMI Intel FPGA IP Isitishi seDatha sokuBonisa (DDC)
I-HDMI Intel FPGA IP DDC isekelwe kwiimpawu ze-I2C (i-SCL kunye ne-SDA) kwaye ifuna abaxhathisi bokutsala. Ukujongana ne-Intel FPGA, kufuneka uguqulele i-5V SCL kunye nenqanaba lophawu lwe-SDA ukuya kwi-FPGA I/O vol.tage level (VCCIO) usebenzisa i-voltagUmguquleli we-e level, njenge-TI TXS0102 njengoko isetyenziswe kwi-Bitec HDMI 2.0 intombi yekhadi. I-TI TXS0102 voltagIsixhobo somguquli wenqanaba le-e sidibanisa izixhasi zokutsala zangaphakathi ukuze kungabikho zixhasi zokutsalela phezulu ezifunekayo.
