Description

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.
