Abstract
A timing circuit can include: a low-precision clock source configured to generate a low-precision clock signal; a high-precision clock source configured to intermittently generate a high-precision clock signal; and a cycle conversion circuit configured to count the pulses of the high-precision clock signal and the low-precision clock signal during a same period, and to obtain a conversion cycle according to count results and a rated cycle of the high-precision clock signal.
