Abstract: This device includes a programmable component having an output able to send an inhibiting signal upon successful configuration of the programmable component and an input able to receive a reconfiguration signal; an automatic burn-in circuit for the configuration of the programmable component, having: selection means which, in a first state, connect the programmable component to a first configuration memory space and, in a second state, connect the programmable component to a second configuration memory space; and watchdog means having an input able to receive the inhibition signal and an output for sending, when no inhibition signal has been received for a predetermined period of time, a configuration signal intended for the programmable component to command the reconfiguration thereof and of the selection means to modify the state thereof.

Abstract: The input interface for a transmit/receive radio station includes an input for receiving a signal either with a variable voltage over a pre-determined voltage range, or an open collector signal having a voltage (0V) corresponding to the low logic state; a first output for the variable voltage signal, and a second open collector output. The first and second outputs are connected to the same input and the input is connected to a reference potential through a first voltage divider bridge, the middle point of which is connected to the positive terminal of an open loop comparator, the output of which is connected to the second output.

Abstract: A circuit for switching clocks includes a first input intended to receive a first clock signal at a frequency alternately equal to a first value or a second value, a second input intended to receive a second clock signal, synchronous with the first clock signal, at a third frequency and an output intended to deliver a third clock signal at a frequency alternately equal to the first value or the third value.
