Whakaahuatanga
Ko te AD9915 he synthesizer mamati tika (DDS) e whakaatu ana i te DAC 12-bit.Ka whakamahia e te AD9915 te hangarau DDS matatau, me te DAC tere o roto, DAC mahi teitei hei hanga i te whakahiato mamati, whakaoti i te reanga teitei e kaha ana ki te whakaputa i te ngaru sinusoidal putanga agile analog ki runga ki te 1.0 GHz.Ma te AD9915 ka taea te peke tere tere me te whakatau pai (64-bit ka taea te whakamahi i te aratau modulus programmable).Ko te AD9915 ano hoki e tuku ana i te waahanga tere me te kaha hikoi kaha.Ka utaina nga kupu whakatikatika me nga kupu whakahaere ki roto i te AD9915 ma te tauranga rangatū, whakarara ranei.Kei te tautoko hoki te AD9915 i te mahi a te kaiwhakamahi mo te hanga i nga ngaru ruruku o te auau, te wahanga, te kaha kaha ranei.He tere teitei, 32-bit parallel data input tauranga kua whakaurua, e taea ai te reiti raraunga teitei mo nga kaupapa whakarereke polar me te tere whakahōtaka o te wahanga, te auau, me te amplitude o nga kupu whakatikatika.
