Monolithic integrated digital circuit including an internal clock generator and circuitry for processing multi-digit signals

摘要

A monolithic integrated digital circuit including at least one circuit for the serial data processing of multi-digit data signals synchronized to a clock system, the serial data processing circuits using a clock signal coming from a clock oscillator which is also integrated. The clock oscillator includes an odd number of ring-connected inverting stages. The output of the oscillator is provided to a counter. When the counter counts a number of pulses equal to the number of digits of the output signal of the data processing circuit, the counter stops the clock oscillator. The system clock signal is applied to both the reset input of the counter and the synchronizing input of the data processing circuit.
