I am wondering if anyone has experience or thoughts on converting a 1PPS signal to LVDS or even LVTTL. The 1PPS GPS signal is defined in ICD-GPS-060B and is logical 1 at 10V or logical 0 at 0V. I have this 1PPS signal coming in as a differential input (1PPS+/1PPS-) coming from an external source (military applications). See image for signal characteristics.
Any pointers on parts or reference designa would be greatly appreciated. Thanks!
We have simulated some 1PPS circuits with the LTC6957 on LTSPice. You may want to refer to this post and see if you can modify the circuit in my response to suit your input signal.
