AC CHARACTERISTICS (470 MHz)
VP = 2.05 V; Tamb =25 °C; test circuit Figs 3 or 4; fi(RF) = 469.950 MHz with ±4.0 kHz deviation; 1200 baud pseudo
random bit sequence modulation (tr = 250 ± 25 s measured between 10% and 90% of voltage amplitude) and 20 kHz
channel spacing; unless otherwise specied.
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. Test circuit Fig.5. Pi(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.12.
4.
f is the frequency offset between the required signal and the interfering signal.
5. 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).
