Customer question:


I am designing a frequency synthesizer using DDS for C band applications. I have shortlisted AD9954, AD9858 and AD9957. I request you to suggest me the right chip for DDS operations with a VCO to generate RF signals. I am looking at 5.5 to 5.8 GHz linear frequency range at 1Mhz frequency steps. Are the above chosen chips capable of performing these operations?
