Ce circuit répond aux exigences de performances et d’encombrement des équipements utilisés dans les infrastructures de réseaux cellulaires multistandards 3G et 4G, tels que CDMA2000, WB-CDMA, LTE, TD-SCDMA et GSM multi-porteuses. Entre autres applications-clés, citons les appareils médicaux portables, les oscilloscopes, les instruments portatifs et alimentés par batteries.<\/p>\n

Ce convertisseur se caractérise par une architecture pipeline différentiel multi-étages avec logique de correction d’erreurs intégrée. Il consomme seulement 122 mW par canal à la fréquence d’échantillonnage de 125 Méch\/seconde et affiche d’excellentes performances dans la plage dynamique sans interférence (SFDR) de 91 dBc à 70 MHz. Avec une fréquence d’échantillonnage en fréquence intermédiaire (FI) pouvant atteindre 200 MHz, il convient aux architectures de réception numérique multimodes.
\nUne version 12 bits double canal référencée AD9635 présentant un brochage compatible facilite la migration entre convertisseurs 12 bits et 14 bits avec des fréquences d’échantillonnage variant de 20 à 125 Méch\/seconde. Disponibles en boîtier LFCSP 32 contacts conforme aux réglementations RoHS, ces deux circuits sont spécifiés dans la plage de température industrielle de -40 °C à +85 °C. Ils sont dotés d’une sortie numérique LVDS série 1,8 V comprenant deux voies par canal.<\/p>\n
