Malangizo Opanga a HDMI Intel® FPGA IP
Maupangiri opangira amakuthandizani kuti mugwiritse ntchito ma IP a Intel FPGA IPs a High-Definition Multimedia Interface (HDMI) pogwiritsa ntchito zida za FPGA. Malangizowa amathandizira mapangidwe a board a HDMI Intel® FPGA IP makanema apakanema.

Malangizo a HDMI Intel FPGA IP Design
Mawonekedwe a HDMI Intel FPGA ali ndi data ya Transition Minimized Differential Signaling (TMDS) ndi mawotchi. Mawonekedwewa amanyamulanso Video Electronics Standards Association (VESA) Display Data Channel (DDC). Makanema a TMDS amakhala ndi mavidiyo, ma audio, ndi data yothandizira. DDC imachokera ku protocol ya I2C. HDMI Intel FPGA IP pachimake imagwiritsa ntchito DDC kuwerenga Extended Display Identification Data (EDID) ndikusintha masinthidwe ndi chidziwitso cha chikhalidwe pakati pa gwero la HDMI ndi sinki.
Malangizo a HDMI Intel FPGA IP Board Design
Pamene mukupanga HDMI Intel FPGA IP yanu, ganizirani malangizo otsatirawa a board.
- Gwiritsani ntchito njira zosapyola ziwiri potsatira ndikupewa kudzera pa stubs
- Gwirizanitsani kusagwirizana kwa awiriwa ndi kulepheretsa kwa cholumikizira ndi chingwe (100 ohm ± 10%)
- Chepetsani skew yapakati-awiri ndi intra-pair kuti mukwaniritse kufunikira kwa chizindikiro cha TMDS
- Pewani kuloza magulu awiri osiyana pa kusiyana kwa ndege yomwe ili pansi
- Gwiritsani ntchito mapangidwe a PCB othamanga kwambiri
- Gwiritsani ntchito zosinthira kuti mukwaniritse kutsata kwamagetsi pa TX ndi RX
- Gwiritsani ntchito zingwe zolimba, monga chingwe cha Cat2 cha HDMI 2.0
Zojambulajambula
Zithunzi zamadongosolo a Bitec mumalumikizidwe operekedwawo zikuwonetsa mitu yama board a Intel FPGA. Kugwiritsa ntchito ulalo wa HDMI 2.0 kumafuna kuti mukwaniritse kutsata kwamagetsi kwa 3.3 V. Kuti mukwaniritse kutsata kwa 3.3 V pazida za Intel FPGA, muyenera kugwiritsa ntchito chosinthira. Gwiritsani ntchito chojambulira chophatikizana ndi DC kapena chosinthira nthawi ngati chosinthira pa cholumikizira ndi cholandila.
Zida zamalonda zakunja ndi TMDS181 ndi TDP158RSBT, zonse zikuyenda pamalumikizidwe a DCcoupled. Mufunika kukokera koyenera pamizere ya CEC kuti muwonetsetse kuti mukugwira ntchito mukamagwiritsa ntchito zida zina zowongolera zakutali. Zithunzi za Bitec schematic ndi CTS-certified. Chitsimikizo, komabe, chimakhala chokhazikika pazogulitsa. Okonza nsanja amalangizidwa kuti atsimikizire kuti chinthu chomaliza chimagwira ntchito bwino.

Hot-plug Detect (HPD)
Chizindikiro cha HPD chimadalira chizindikiro champhamvu cha + 5V chomwe chikubwera, mwachitsanzoample, pini ya HPD ikhoza kutsimikiziridwa pokhapokha chizindikiro cha + 5V Power kuchokera kugwero chadziwika. Kuti mulumikizane ndi FPGA, muyenera kumasulira chizindikiro cha 5V HPD kupita ku FPGA I/O vol.tage level (VCCIO), pogwiritsa ntchito voltage level translator monga TI TXB0102, amene alibe kukoka-mmwamba resistors Integrated. Gwero la HDMI liyenera kutsitsa chizindikiro cha HPD kuti chizitha kusiyanitsa pakati pa siginecha yoyandama ya HPD ndi voliyumu yayikulu.tagndi chizindikiro cha HPD. Sink ya HDMI + 5V Mphamvu yamagetsi iyenera kumasuliridwa kukhala FPGA I/O voltage level (VCCIO). Chizindikirocho chiyenera kugwetsedwa mofooka ndi chotsutsa (10K) kuti chisiyanitse chizindikiro cha Mphamvu yoyandama + 5V pamene sichiyendetsedwa ndi gwero la HDMI. Gwero la HDMI +5V Power siginecha ili ndi chitetezo chopitilira pano chosaposa 0.5A.
HDMI Intel FPGA IP Display Data Channel (DDC)
HDMI Intel FPGA IP DDC idakhazikitsidwa pazizindikiro za I2C (SCL ndi SDA) ndipo imafuna zotsutsa zokoka. Kuti mulumikizane ndi Intel FPGA, muyenera kumasulira siginecha ya 5V SCL ndi SDA kupita ku FPGA I/O vol.tage level (VCCIO) pogwiritsa ntchito voltage level translator, monga TI TXS0102 monga momwe amagwiritsidwira ntchito mu Bitec HDMI 2.0 khadi lamwana. Chithunzi cha TI TXS0102tagChipangizo chomasulira cha e level chimaphatikiza zopinga zamkati zokokera mmwamba kuti pasakhale zopinga zokokera mmwamba zomwe zimafunikira.

Zindikirani: Chikalatachi chili ndi malangizo a mapangidwe a HDMI Intel FPGA omwe adachotsedwa ku AN 745: Malangizo Opanga a DisplayPort ndi HDMI Interfaces ndikusinthidwanso AN 745: Malangizo Opanga a Intel FPGA DisplayPort Interface. |
Malingaliro a kampani Intel Corporation Maumwini onse ndi otetezedwa. Intel, logo ya Intel, ndi zizindikiro zina za Intel ndi zizindikiro za Intel Corporation kapena mabungwe ake. Intel imalola kuti FPGA yake ndi zinthu zopangira semiconductor ziziwoneka bwino malinga ndi chitsimikizo cha Intel koma ili ndi ufulu wosintha zinthu ndi ntchito zilizonse nthawi iliyonse popanda kuzindikira. Intel sakhala ndi udindo kapena udindo chifukwa chakugwiritsa ntchito kapena kugwiritsa ntchito zidziwitso zilizonse, malonda, kapena ntchito zomwe zafotokozedwa pano kupatula monga momwe Intel adavomerezera momveka bwino. Makasitomala a Intel amalangizidwa kuti apeze mtundu waposachedwa kwambiri wamakina a chipangizocho asanadalire zidziwitso zilizonse zosindikizidwa komanso asanayike maoda azinthu kapena ntchito.
Mayina ena ndi mtundu zitha kunenedwa kuti ndi za ena.
