Features

very low power consumption. The CX24113A has a built-in auto-tuning machine that eliminates the need for software calibration and accelerates the calibration time. The on-chip fractional synthesizer enables fine frequency step size without adversely affecting lock time. The CX24113 does not require a balun, thus reducing external bill of materials (BOM) cost. Its highly integrated design saves valuable board space and simplifies RF layout. The company’s broad portfolio of semiconductor products also includes client-side xDSL and cable modem solutions, home network processors, broadcast video e.
