AD9914BCPZ IC DDS 12BIT 88LFCSP

Whakaahuatanga

Ko te AD9914 he synthesizer mamati tika (DDS) e whakaatu ana i te DAC 12-bit.Ka whakamahia e te AD9914 te hangarau DDS matatau, me te DAC tere o roto, DAC mahi teitei hei hanga i te whakahiatotanga mamati, whakaotihia te auau teitei e kaha ana ki te whakaputa i te ngaru sinusoidal putanga tairitenga-a-roto ki te 1.4 GHz.Ma te AD9914 ka taea te peke tere tere me te whakatau pai (64-bit ka taea te whakamahi i te aratau modulus programmable).Ko te AD9914 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 AD9914 ma te tauranga whakauru/putanga rangatū, whakarara ranei.Kei te tautoko hoki te AD9914 i tetahi aratau tiihi raina kua tautuhia e te kaiwhakamahi mo te whakaputa i nga ngaru ruruku raina 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.Ko te AD9914 kua tohua kia mahi i runga i te awhe wera o te ahumahi (tirohia te waahanga Whakatauranga Morahi Rawa).
