Abstract: In one aspect of the present invention, a converter is provided comprising a capacitive coupling arranged to receive said input signal to be converter, and a conversion circuitry coupled to the capacitive coupling to produce the converted output signal. A biasing circuit is further arranged to facilitate a fast transition in the converted output signal in response to an active transition in the input signal.

Abstract: A circuit (90) converts a true ECL signal to a true TTL signal. The circuit includes a differential circuit (180) that receives an ECL signal having high and low values. The differential circuit produces a differential signal therefrom that has a high value in response to one of the high and low values of the true ECL signal, and a low value in response to the other of the high and low values of the true ECL signal. A first translator circuit (36, 64) has an input (32) coupled to the differential circuit (180). The first translator circuit (36, 64) transmits a true low TTL output (56) signal having a voltage level referenced to the voltage level of a TTL low supply voltage in response to receiving a high value of the differential signal. A second translator circuit (46, 52) has an input (38) and is coupled to a TTL high supply voltage and the output (56).
