Notes
1. The bit error rate BER is measured using the test facility shown in Fig.12. Note that the BER test facility contains a
digital input filter equivalent to the one used in the PCA5000A, PCF5001 and PCD5003 POCSAG decoders.
2. Capacitor C16 requires re-adjustment to compensate temperature drift.
3. ∆f is the frequency offset between the required signal and the interfering signal.
4. Turn-on time is defined as the time from pin RE going HIGH to the reception of valid data on output pin DO. Turn-on
time is measured using an external oscillator (turn-on time using the internal oscillator is dependent upon the
oscillator circuitry).
