channel spacing; unless otherwise specified.
Notes
1.
The bit error rate BER is measured using the test facility shown in Fig.13. Note that the BER test facility contains a
digital input filter equivalent to the one used in the PCA5000A, PCF5001 and PCD5003 POCSAG decoders.
Capacitor C16 requires re-adjustment to compensate temperature drift.
Test circuit Fig.5. P
i(mix)
is the maximum available power at the input of the test board. The bit error rate BER is
measured using the test facility shown in Fig.13.
f is the frequency offset between the required signal and the interfering signal.
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).
