Other Parts Discussed in Thread: LMH1983,
Previously when working on a LMH1983 circuit it was recommended that I use Epson's VG-4231CB 27.0000M-GGCZ3 for my VCXO because of its smaller size and better phase noise performance.
My question is since the VG-4231CB 27.0000M-GGCZ3 has a minimum input impedance of 10M, then do I need the LMP7711 buffer? I think it was only there because the original VCXO recommended by TI was CTS 357LB3I027M0000 which has an input impedance of 10K.
Thanks!
