Le syst\u00e8me \u2018Head-Unit\u2019 complexe du v\u00e9hicule doit \u00eatre capable d&rsquo;accepter plusieurs tuners, de g\u00e9rer la dissipation thermique et de recevoir plusieurs c\u00e2bles d&rsquo;antenne. En outre, les signaux analogiques re\u00e7us rajoutent du bruit lors de leur propagation depuis l&rsquo;antenne jusqu&rsquo;au syst\u00e8me \u2018Head-Unit\u2019 du v\u00e9hicule. Enfin, le traitement bande de base fait appel \u00e0 un circuit d\u00e9di\u00e9, ce qui suppose une nouvelle conception pour chaque norme radio utilis\u00e9e dans le monde.<\/p>\n<p>Gr\u00e2ce \u00e0 cette solution, des tuners RF to Bits peuvent d\u00e9sormais \u00eatre install\u00e9s dans un environnement moins bruit\u00e9, \u00e0 proximit\u00e9 de l&rsquo;antenne, pour minimiser le bruit. Pendant ce temps, les sorties num\u00e9riques de ces tuners sont s\u00e9rialis\u00e9es \u00e0 l&rsquo;aide d&rsquo;un SerDes GMSL (Gigabit Multimedia Serial Link) sur un seul c\u00e2ble coaxial bon march\u00e9. L&rsquo;alimentation \u00e9lectrique du tuner distant est \u00e9galement fournie par ce m\u00eame c\u00e2ble. Non seulement cette configuration am\u00e9liore les performances radio, mais elle r\u00e9duit \u00e9galement le poids du v\u00e9hicule ainsi que sa consommation.<\/p>\n<p>Retirer tous les tuners du syst\u00e8me \u2018Head-Unit\u2019 permet de gagner de la place, mais aussi de r\u00e9duire la complexit\u00e9 syst\u00e8me et la chaleur dissip\u00e9e dans ce syst\u00e8me. Par exemple, dans une radio 4 canaux, 4 W peuvent \u00eatre gagn\u00e9s au niveau du \u2018Head-Unit\u2019. En outre, le tuner d\u00e9port\u00e9 assure le traitement de bande de base par logiciel sur un SoC automobile du march\u00e9. Cette approche SDR (Software Defined Radio) rend possible une mise en \u0153uvre tr\u00e8s souple en \u00e9vitant le recours \u00e0 un processeur de bande de base d\u00e9di\u00e9. En changeant simplement le logiciel, n&rsquo;importe quelle norme radio mondiale peut d\u00e9sormais \u00eatre support\u00e9e.<\/p>\n<hr \/>\n<p>\u00ab\u00a0En proposant aux OEM une solution permettant de r\u00e9duire le nombre de c\u00e2bles, nous leur permettons aussi de gagner de la place, de faciliter la conception et d&rsquo;am\u00e9liorer les performances,\u00a0\u00bb d\u00e9clare William Chu, Directeur G\u00e9n\u00e9ral Automobile chez Maxim Integrated. \u00ab\u00a0Maxim est la seule soci\u00e9t\u00e9 \u00e0 proposer les trois composants RF, SerDes et alimentation dans sa solution.\u00a0\u00bb<\/p>\n<p>Ainsi, cette solution de tuner d\u00e9port\u00e9 comprend&nbsp;le r\u00e9cepteur radio hybride analogique\/num\u00e9rique, \u00e0 frontal RF to Bits MAX2175, le d\u00e9-s\u00e9rialiseur GMSL 14 bits MAX96708 et le s\u00e9rialiseur GMSL 14 bits MAX96711, ainsi qu\u2019un r\u00e9gulateur lin\u00e9aire LDO 1A MAX15027 et un convertisseur \u00e0 d\u00e9coupage synchrone 36 V\/ 2 A MAX20002.<\/p>\n<p>Pour \u00e9valuer les performances de ce r\u00e9cepteur, les kits MAX2175R1EVKIT# et MAX2175J1EVKIT# sont \u00e9galement propos\u00e9s.<br \/>\n&nbsp; &nbsp;<\/p>\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Gr\u00e2ce au tuner d\u00e9port\u00e9 MAX2175 de Maxim Integrated Products, les concepteurs peuvent vraiment simplifier la conception d&rsquo;un syst\u00e8me \u2018Head-Unit\u2019 automobile et aussi r\u00e9duire le nombre de c\u00e2bles.
