HDMI Intel FPGA IP Design Awọn Itọsọna

HDMI Intel FPGA ni wiwo ni o ni Transition Dindindin Iyatọ Signaling (TMDS) data ati aago awọn ikanni. Ni wiwo tun gbejade a Video Electronics Standards Association (VESA) Ifihan Data ikanni (DDC). Awọn ikanni TMDS gbe fidio, ohun, ati data iranlọwọ. DDC naa da lori ilana I2C. HDMI Intel FPGA IP mojuto nlo DDC lati ka Alaye Idanimọ Ifihan Afikun (EDID) ati iṣeto ni paṣipaarọ ati alaye ipo laarin orisun HDMI ati rii.

HDMI Intel FPGA IP Board Design Tips

Nigbati o ba n ṣe apẹrẹ HDMI Intel FPGA IP eto rẹ, ro awọn imọran apẹrẹ igbimọ atẹle wọnyi.

• Lo ko ju meji nipasẹs fun itọpa ati yago fun nipasẹ awọn stubs
• Baramu impedance bata iyatọ si ikọlu ti asopo ati apejọ okun (100 ohm ± 10%)
• Dinkuro laarin bata ati skew intra-bata lati pade ibeere skew ifihan agbara TMDS
• Yago fun lilọ ipa-ọna meji iyatọ lori aafo kan ninu ọkọ ofurufu labẹ
• Lo boṣewa ga iyara PCB oniru ise
• Lo awọn iyipada ipele lati pade ibamu itanna ni mejeeji TX ati RX
• Lo awọn kebulu to lagbara, gẹgẹbi okun USB Cat2 fun HDMI 2.0

Awọn aworan atọka

Awọn aworan atọka Bitec ninu awọn ọna asopọ ti a pese ṣe apejuwe topology fun awọn igbimọ idagbasoke Intel FPGA. Lilo HDMI 2.0 topology ọna asopọ nbeere ki o pade ibamu itanna 3.3 V. Lati pade ibamu 3.3 V lori awọn ẹrọ FPGA Intel, o nilo lati lo iyipada ipele kan. Lo atupapọ DC kan tabi retimer bi ipele ipele fun atagba ati olugba.

Awọn ẹrọ olutaja ita jẹ TMDS181 ati TDP158RSBT, mejeeji nṣiṣẹ lori awọn ọna asopọ DCcoupled.
