Abstract
In some embodiments related to a smart edge detector, the smart edge detector uses a second clock in a receiver domain (e.g., clock CLK_D) to trigger a first flip-flop having a first clock in a transmitter domain (e.g., clock CLK_D) as input data for the first flip-flop. The clock CLK_Dthrough a delay cell also triggers a second flip-flop having the same clock CLK_Das input data for the second flip-flop. Based on the output of the first flip-flop (e.g., output S) and of the second flip-flop (e.g., output S), the embodiments determine whether the rising and or falling edge of clock CLK_Dshould be used for triggering in a transmitting and receiving application. The embodiments are applicable in both situations where the rising edge or falling edge of clock CLK_Dis used as a triggering edge. Other embodiments are also disclosed.
