The initial plan was to take the PPS and connect it to the FPGA. The FPGA samples the line and then generates a similar pulse 20us width (simple clock counter) instead of 80us (which is provided by the gps) and then connect the output to the level translator and get what I desired. But what...
Hello, I have a GPS module, an FPGA spartan 3 development kit and a voltage switch 3.3v -10v and vice versa.
I need to take the 1 pulse per second (PPS) which is coming from the GPS and change its width 80µs to 20µs, rise time to 20ns max and amplitude from 3.3v to 10v.
Everyone is connected...
