LTC2208 ADC module for DIY HF receiver/transceiver.
I'm not an electronics/rf proffesional so design is non optimal, has a space to improve e.t.c.
It has LPF in the input- cutoff frequency is around 60MHz.
RD/RE - use 0 resistor to disable or enable randomizer.
With my project for QMTech module it has not good IMD3 DR for this ADC - around 70dbFS, I think it because of traces (designed for LVDS mode) on the QMTech module,
but also can be partially caused by design of this ADC board.
