18.1 Reset timing requirements
18.2 Oscillator start-up time
The clock applied to the PN512 provides a time basis for the synchronous system’s
encoder and decoder. The stability of the clock frequency, therefore, is an important factor
for correct operation. To obtain optimum performance, clock jitter must be reduced as
much as possible. This is best achieved using the internal oscillator buffer with the
recommended circuitry.
If an external clock source is used, the clock signal must be applied to pin OSCIN. In this
case, special care must be taken with the clock duty cycle and clock jitter and the clock
quality must be verified.
The reset signal is filtered by a hysteresis circuit and a spike filter before it enters the
digital circuit. The spike filter rejects signals shorter than 10 ns. In order to perform a reset,
the signal must be LOW for at least 100 ns.
If the PN512 has been set to a Power-down mode or is powered by a V
start-up time for the PN512 depends on the oscillator used and is shown in
