Table 3-12: Receiver characteristics (including Digital Demodulator and PAM-Receiver)
3.10 Characteristics of externally supplied 32.768kHz clock signal
The 32.768kHz clock signal applied to CLK32 has to be a rectangular waveform with a duty cycle of
10% up to 90%. The frequency accuracy has to be better than 250ppm. The rise time and fall time of
the 32.768kHz signal must be below 10
µ
s. The amplitude must satisfy the requirements in Table 3-5.
