AD9957BSVZ IC DDS 1GHZ 14BIT 100TQFP

Kev piav qhia

AD9957 ua haujlwm raws li universal I / Q modulator thiab agile upconverter rau kev sib txuas lus systems uas tus nqi, qhov loj me, kev siv hluav taws xob thiab kev ua haujlwm zoo yog qhov tseem ceeb.AD9957 integrates high speed Direct Digital Synthesizer (DDS), kev ua haujlwm siab, kev kub ceev 14-ntsis digital rau analog converter (DAC), moos multiplier circuitry, cov ntxaij lim dej digital thiab lwm yam DSP ua haujlwm rau ib nti.Nws muab rau lub hauv paus band up-hloov rau cov ntaub ntawv kis tau tus mob nyob rau hauv ib tug wired los yog wireless kev sib txuas lus system.AD9957 yog qhov thib peb muab rau hauv tsev neeg ntawm quadrature digital upconverters (QDUCs), uas suav nrog AD9857 thiab AD9856.Nws muab kev ua tau zoo nce hauv kev khiav hauj lwm ceev, kev siv hluav taws xob thiab kev ua haujlwm spectral.Tsis zoo li nws cov neeg ua ntej, nws tseem txhawb nqa 16-ntsis serial input hom rau I / Q cov ntaub ntawv hauv paus band.Cov cuab yeej tuaj yeem hloov tau los ua haujlwm los ua ib lub suab sinusoidal los yog ua DAC interpolating.Lub Sijhawm Clock input circuitry muaj xws li siv lead ua oscillator, kev kub ceev sib faib-los ntawm ob lub tswv yim, thiab lub suab qis PLL rau kev sib npaug ntawm qhov siv moos zaus.
