When in baseband mode, AD9161/AD9162/AD9163/AD9164 DACs support DOCSIS 3.1 cable infrastructure compliance. The AD9161/AD9162 DACs use a minimum of two carriers to operate across a full 1.794GHz spectrum. The AD9163/AD9164 DACs use a minimum of one carrier to operate up to a 1GHz (AD9163) or 1.791GHz (AD9164) signal bandwidth. A 2x Interpolator filter (FIR85) allows the AD9161/AD9162/AD9163 DACs to operate at lower data rates and converter clocking. This reduces the overall system power and eases the filtering requirements.
