Abstract
The phase detection circuit may allow an operating speed of a semiconductor circuit to be increased irrespective of whether a combinational logic circuit within the semiconductor circuit operates at lower operating speeds. The phase detection circuit may adjust a data rate of an input data signal and selectively enable reference signals and error signals. The phase detection circuit may be included within a clock data recovery circuit.
