I am trying to select a 160MHz clock oscillator for my FPGA. The least expensive I found was either LVDS or LVPECL type for this frequency. I used a CMOS type before, so the output of the oscillator was GND to VDD. I wanted to ask if I could use LVDS or LVPECL type in the same configuration as CMOS, that is, by connecting OUTN to GND in order to obtain oscillations GND to VDD? Would I still need the 100 Ohm resistor between the terminals? Why?
Also, why are these oscillators so expensive? Are there alternatives?
