Condition
Measured at a data rate of 1.2
kbit/s, 60 kHz IF and 20 kHz
frequency separation with a bit
error rate better than 10
other settings see p.12.
Depends on external components
placement
Receive mode, series equivalent.
For matching details see “Input/
output matching” p. 13.
With precharging, 9.6 kbit/s
Without precharging, 9.6 kbit/s
With precharging, 1.2 kbit/s
Without precharging, 1.2 kbit/s
See “Demodulator precharging
for reduced turn-on time” p. 18.
Complies with EN 300 220 class
2 receiver requirements.
See p. 15 for more details.
The IF is programmable. Either
60 kHz, 200 kHz or 455 kHz can
be chosen.
An optional external IF filter can
be used if 455 kHz is chosen.
The impedance level is 1.5 kΩ
The crystal frequency accuracy
and drift (ageing and
temperature dependency) will
determine the frequency accuracy
of the transmitted signal.
C151 and C161 are loading
capacitors, see page 14.
