AD9957BSVZ IC DDS 1GHZ 14BIT 100TQFP

Whakaahuatanga

Ko te AD9957 te mahi hei whakarereke I/Q ao me te kaitahuri huritao mo nga punaha whakawhitiwhiti he mea nui te utu, te rahi, te whakapau hiko me te mahi hihiri.Ko te AD9957 e whakauru ana i te tere teitei Direct Digital Synthesizer (DDS), he mahi nui, he tere tere 14-bit mamati ki te kaitahuri tairitenga (DAC), karaka karaka hiko, whiriwhiringa mamati me etahi atu mahi DSP ki runga i te maramara kotahi.E whakarato ana mo te roopu-whakawhitinga turanga mo te tuku raraunga i roto i te punaha whakawhitiwhiti waea, ahokore ranei.Ko te AD9957 te tuatoru o nga tuku i roto i te whanau o nga kaitahuri matihiko tapawha (QDUC), kei roto ko te AD9857 me AD9856.Ka whakawhiwhia e ia nga hua o te mahi i roto i te tere whakahaere, te whakapau hiko me te mahi whakakitenga.Kaore i rite ki o mua, kei te tautoko ano i te aratau rangatū 16-bit mo nga raraunga roopu turanga I/Q.Ka taea te whakarite te taputapu ki te mahi hei puna sinusoidal oro kotahi, hei DAC hono ranei.Kei roto i te ara iahiko urunga Karaka Tohutoro he oscillator tioata, he whakaurunga wehenga-ma-rua, me te PLL haruru iti mo te whakareatanga o te auau karaka tohutoro.
