We have implemented the circuit design comprising of phase detector, limiter, loop filter, NCO and clock divider in hardware using FPGA. The disciplined 10MHz is measured to have a long term (10,000 sec) stability of 1.7 x 10-10. In case of non-availability of NavIC 1PPS, the circuit is designed to work with an internal 1PPS …
