HDMI Intel FPGA IP Design Guidelines
Khokahano ea HDMI Intel FPGA e na le data ea Transition Minimized Differential Signaling (TMDS) le likanale tsa oache. Khokahano e boetse e na le Video Electronics Standards Association (VESA) Display Data Channel (DDC). Liteishene tsa TMDS li na le data, audio, le data e thusang. DDC e ipapisitse le protocol ea I2C. The HDMI Intel FPGA IP core e sebelisa DDC ho bala Extended Display Identification Data (EDID) le phapanyetsano ea tlhophiso le lintlha tsa boemo lipakeng tsa mohloli oa HDMI le sinki.
HDMI Intel FPGA IP Board Design Tips
Ha o ntse o rala sistimi ea hau ea HDMI Intel FPGA IP, nahana ka malebela a latelang a moralo oa boto.
- Sebelisa li-vias tse fetang tse peli ho latela mohlala 'me u qobe ka li-stubs
- Bapisa sekheo sa para e fapaneng le sehokelo sa sehokelo le kopano ea thapo (100 ohm ± 10%)
- Fokotsa li-inter-pair le intra-pair skew ho fihlela tlhoko ea TMDS signal skew
- Qoba ho tsamaisa para e fapaneng holim'a lekhalo sefofaneng se ka tlase
- Sebelisa mekhoa e tloaelehileng ea meralo ea PCB ea lebelo le holimo
- Sebelisa li-level shifters ho kopana le melao ea motlakase ho TX le RX ka bobeli
- Sebelisa lithapo tse matla, joalo ka thapo ea Cat2 bakeng sa HDMI 2.0

Ho sebelisa topology ea khokahano ea HDMI 2.0 ho hloka hore u kopane le 3.3 V tsa motlakase. Ho kopana le 3.3 V ho latela lisebelisoa tsa Intel FPGA, o hloka ho sebelisa boemo bo feto-fetohang. Sebelisa mochine o kopanyang oa DC kapa retimer e le sesebelisoa sa boemo ba transmitter le se amohelang.
