1.2.2 TX-BPF
The staircase waveform generated by the FG-DAC in combination with the divider by 16 has
to be filtered by an anti-aliasing filter because the SC-Filter clock is not synchronous to the
FSK-signal. There is a 6th order bandpass filter, which is also used as receive-filter in
receive-mode, implemented to reduce the FSK-spectrum. The filter-clock gets canceled by a
smoothing filter at the end of this filter-chain.
Both, AAF and SMF will be designed in a way to move their corner-frequencies according to
the frequency-band programmation. With the help of the resonator built with the transformer
and attached capacitor, the unwanted frequencies (SC-clk, harmonics) are attenuated so that
the signal spectrum at the transformer-output passes the following specification

1.2.3 Output-Stage
AS5502: The output stage is designed to amplify the FSK-signal by a factor of 7 with the
help of an external buffer-stage to 14Vpp. The transfer from the 5V circuitry (asic) to the 24V
buffer-structure is done by current-source outputs. The on-chip resistor-network is done in a
way to shift the DC-operating point from 2.5V (on chip) to 12V (ext. buffer). With this
output-voltage a transformer with a ratio of 2.5:1 can be used (VLmax=2Vrms). The buffer
gives a very low impedance which is needed to modulate the power-line (Line-impedance: 5
.. 150ohm).
AS5501 is available for 12V buffer-supply
- amplification-factor: 3.5 instead of 7.0
- buffer DC-operating point: 6V instead of 12V
