In the circuit is the phase-lock loop frequency doubler. This circuit can switch the 1MHz standard frequency into the 10MHz reference frequency, and the stability and precision of the output frequency are the same with the 1MHz standard frequency. The PLL integrated circuit in the circuit is XR210. The 1MHz reference signal is coupled on the 4-pin of IC1 by capacitor C1, and the output signal of the counter 9316 is added on the 6-pin, they are compared by the phase comparator inside IC1. The output of the phase comparator is filtered by capacitor C4.
