    摘要: This description relates to an edge detector including a pulse generator configured to generate a first pulse when a first clock and a second clock are at a same logic level and generate a second pulse when the first clock and the second clock are at different logic levels. The edge detector further includes a first RC circuit configured to charge the first pulse and a second RC circuit configured to charge the second pulse. The edge detector further includes a circuitry that, based on a width of the first pulse or of the second pulse, is configured to provide a select signal to select an edge of the second clock for triggering.

    摘要: 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_D2) to trigger a first flip-flop having a first clock in a transmitter domain (e.g., clock CLK_D1) as input data for the first flip-flop. The clock CLK_D2 through a delay cell also triggers a second flip-flop having the same clock CLK_D1 as input data for the second flip-flop. Based on the output of the first flip-flop (e.g., output S1) and of the second flip-flop (e.g., output S2), the embodiments determine whether the rising and or falling edge of clock CLK_D2 should 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_D1 is used as a triggering edge. Other embodiments are also disclosed.
