HDMI Intel FPGA IP Design Guidelines
Lub HDMI Intel FPGA interface muaj Transition Minimized Differential Signaling (TMDS) cov ntaub ntawv thiab moos raws. Lub interface kuj yog Video Electronics Standards Association (VESA) Display Data Channel (DDC). TMDS channels nqa cov yeeb yaj kiab, suab, thiab cov ntaub ntawv pabcuam. DDC yog raws li I2C raws tu qauv. Lub HDMI Intel FPGA IP core siv DDC los nyeem Cov Ntaub Ntawv Qhia Ntxiv Ntxiv (EDID) thiab sib pauv kev teeb tsa thiab cov ntaub ntawv xwm txheej ntawm HDMI qhov chaw thiab dab dej.
HDMI Intel FPGA IP Board Tsim Cov Lus Qhia
Thaum koj tab tom tsim koj lub HDMI Intel FPGA IP system, xav txog cov lus qhia tsim qauv hauv qab no.
- Siv tsis pub ntau tshaj ob vias rau ib txoj kab thiab tsis txhob siv cov stubs
- Ua kom sib txawv khub impedance rau lub impedance ntawm lub connector thiab cable los ua ke (100 ohm ± 10%)
- Txo kev sib koom ua ke thiab sib koom ua ke skew kom tau raws li TMDS teeb liab skew yuav tsum tau
- Tsis txhob routing ib khub sib txawv ntawm qhov sib txawv ntawm lub dav hlau hauv qab
- Siv cov txheej txheem kev kub ceev PCB tsim kev coj ua
- Siv cov theem hloov pauv kom tau raws li kev ua raws li hluav taws xob ntawm TX thiab RX
- Siv cov cables uas muaj zog, xws li Cat2 cable rau HDMI 2.0
Schematic daim duab
Lub Bitec schematic daim duab nyob rau hauv cov kev sib txuas qhia qhia lub topology rau Intel FPGA kev loj hlob boards. Siv HDMI 2.0 txuas topology xav kom koj ua tau raws li 3.3 V hluav taws xob ua raws. Txhawm rau ua kom tau raws li 3.3 V ua raws li Intel FPGA cov khoom siv, koj yuav tsum tau siv cov qib hloov pauv. Siv DC-coupled redriver lossis retimer raws li qib hloov pauv rau lub transmitter thiab receiver.
Cov khoom siv sab nraud yog TMDS181 thiab TDP158RSBT, ob qho tib si khiav ntawm DCcoupled txuas. Koj xav tau kev rub tawm kom raug ntawm CEC kab kom ntseeg tau tias kev ua haujlwm tau zoo thaum ua haujlwm nrog lwm tus neeg siv khoom siv tswj chaw taws teeb. Bitec schematic daim duab yog CTS-certified. Daim ntawv pov thawj yog, txawm li cas los xij, cov khoom lag luam tshwj xeeb. Platform designers raug qhia kom lees paub cov khoom kawg rau kev ua haujlwm kom raug.

Kub-Plug Detect (HPD)
Lub teeb liab HPD nyob ntawm qhov xaim hluav taws xob + 5V, piv txwv liample, tus pin HPD tuaj yeem lees paub tsuas yog thaum kuaj pom lub zog +5V lub zog los ntawm qhov chaw. Txhawm rau cuam tshuam nrog FPGA, koj yuav tsum txhais 5V HPD teeb liab rau FPGA I / O voltage theem (VCCIO), siv lub voltage theem txhais xws li TI TXB0102, uas tsis muaj rub-up resistors integrated. Ib qho HDMI qhov yuav tsum tau rub tawm HPD teeb liab kom nws tuaj yeem ntseeg tau qhov sib txawv ntawm cov teeb liab HPD ntab thiab qhov siab siab.tage theem HPD teeb liab. HDMI dab dej + 5V Fais fab teeb liab yuav tsum tau muab txhais ua FPGA I/O voltage theem (VCCIO). Lub teeb liab yuav tsum tsis muaj zog rub tawm nrog lub resistor (10K) kom sib txawv qhov ntab + 5V fais fab teeb liab thaum tsis tsav los ntawm HDMI qhov chaw. Ib qho HDMI qhov chaw + 5V Lub zog hluav taws xob muaj kev tiv thaiv tam sim no tsis pub ntau tshaj 0.5A.
HDMI Intel FPGA IP Zaub Cov Ntaub Ntawv Channel (DDC)
Lub HDMI Intel FPGA IP DDC yog raws li I2C teeb liab (SCL thiab SDA) thiab yuav tsum tau rub-up resistors. Txhawm rau cuam tshuam nrog Intel FPGA, koj yuav tsum txhais 5V SCL thiab SDA teeb liab theem rau FPGA I / O voltage theem (VCCIO) siv lub voltage qib txhais lus, xws li TI TXS0102 raws li siv hauv Bitec HDMI 2.0 tus ntxhais daim npav. The TI TXS0102 voltage qib txhais cov cuab yeej sib txuas nrog cov rub-up resistors kom tsis txhob muaj cov kab hluav taws xob rub-up resistors.
