  • The RHFOSC04 is a crystal oscillator driver and divider. It consists of an oscillator section and 4-stage ripple-carry binary counter. The oscillator section allows the implementation of crystal oscillator circuits. The output is buffered and it is controlled by a 2-bit digital cell to deliver one among four divided frequency, from F to F/2, F/4 and F/8 frequencies. A disable function is available to set the circuit in power-down mode while keeping a high impedance output.

    Designed in rad-hard rules on robust CMOS technology already proven in space, the RHFOSC04 shows an excellent stability in total-ionizing-dose (TID) up to 300 krad(Si) and it is SEL-free and SET-free up to 125 MeV.cm²/mg.
    It comes in hermetic ceramic Flat-10 lead, and can operate from -55 °C to +125 °C ambient temperature.
