Hana ʻia ka AD9957 ma ke ʻano he modulator I/Q a me ka agile upconverter no nā ʻōnaehana kamaʻilio kahi koʻikoʻi ke kumukūʻai, ka nui, ka hoʻohana mana a me ka hana ikaika.Hoʻohui ka AD9957 i kahi kiʻekiʻe Direct Digital Synthesizer (DDS), kahi hana kiʻekiʻe, kiʻekiʻe kiʻekiʻe 14-bit kikohoʻe i analog converter (DAC), uaki multiplier circuitry, nā kānana kikohoʻe a me nā hana DSP ʻē aʻe i hoʻokahi pahu.Hāʻawi ia no ka hoʻololi ʻana i ka hui kumu no ka lawe ʻana i ka ʻikepili i loko o kahi ʻōnaehana kamaʻilio uea a uea paha.ʻO ka AD9957 ke kolu o ka hāʻawi ʻana i loko o kahi ʻohana o kahi quadrature digital upconverters (QDUCs), e komo pū ana me AD9857 a me AD9856.Hāʻawi ia i nā lanakila hana ma ka wikiwiki o ka hana, ka hoʻohana mana a me ka hana spectral.ʻAʻole like me kona mau mua, kākoʻo pū ia i kahi mode input serial 16-bit no ka ʻikepili base band I/Q.Hiki ke hoʻolālā ʻia ka hāmeʻa e hana ma ke ʻano he kumu sinusoidal kani hoʻokahi a i ʻole he DAC interpolating.Aia i loko o ka circuitry input Clock kahi oscillator kristal, kahi hoʻokomo hoʻokaʻawale kiʻekiʻe-me-ʻelua, a me kahi leo haʻahaʻa PLL no ka hoʻonui ʻana i ke alapine o ka uaki kuhikuhi.
