Enhanced Pager Decoder for POCSAG
PCD5003A
Notes
1.
32768 Hz reference signal: 32 pulses per 75 clock cycles, alternately separated by 1 or 2 pulse periods
(pulse duration: t
RFP
). The timing is shown in Fig.15.
50 Hz reference signal: square-wave.
The fall time may be faster than prescribed in the I
2
C-bus specification for very low load capacitance values.
To increase the fall time external capacitance is required.
Duration depends on programmed bit rate; after reset t
ZSU
= 1.5 bits.
Nominal values; pause in 12th data bit (see Table 12).
