Example embodiments may provide a counter capable of outputting a count value after holding the count value for an amount of time and a phase locked loop (PLL) including the counter. The counter may include a selection unit that may selectively output a clock signal and a hold signal in response to a selection signal and a counting unit that may perform a counting operation in response to the clock signal and output a count value obtained by the counting operation after holding the count value for an amount of time in response to the hold signal. The counter may stably output an accurate count value regardless of transmission delays.
