1. Is there any recommended transformer Balun for making the DAC output and the clock input single ended for circuit design using AD9912 Synthesizers ?
2. For wide output band operation (25-400), is a single LPF operating at 400 will suffice for rejecting harmonics or a switchable network like LPF 50MHz for Harmonic rejection between 25-50, LPF 100 for 51-100, LPF 200 for 100-200 and LPF 400 for 200+ frequencies. Out of the above 2, which design is recommended ?
Thank you !
