So I have this new gig making a very low cost TDR system for soil moisture and conductivity, for use in agriculture. All very interesting and topical, what with droughts and low aquifers and all.
As one does, I'm planning to use a fast ramp and two comparators to generate the TX pulse and the sampling gate. One will have a fixed comparison voltage, and the other one's will be set by a DAC, or possibly by a slower ramp, depending on the BOM vs performance tradeoff we wind up with.
Sooo, naturally I pulled out my fave LVDS line receiver, the FIN1002. It has nice 250-300 ps edges and pretty low jitter, comes in SOT23, and and costs 30 cents on LCSC.
It even has SPICE models, but of course they're nasty encrypted HSPICE things.
TI's seem to be the same.
Anybody got a nice LVDS receiver with a real SPICE model that mere mortals are allowed to use?
Thanks
