Receiver Functions
2.5.3.1
In order to additionally reduce the bit error rate in severe conditions, the IPAC performs
oversampling of the received signal and uses majority decision logic.
The receiver consists of a differential to single ended input stage, a peak detector and a
set of comparators. Additional noise immunity is achieved by digital oversampling after
the comparators. The following
figure 29
describes the functional blocks of the receiver
(for receiver tansformer ratio 2:1). The equivalent internal circuit for transformer ratio 1:1
(CONF:AMP=1) is shown in
figure 26
.

Receiver Circuit
The input stage works together with external 10 k
resistors to match the input voltage
to the internal thresholds. The data detection thresholds are chosen to 35 % of the peak
voltage to increase the performance in extended passive bus configurations. However
they never go below 85 mV with respect to the line signal level. This guarantees a
maximum line attenuation of at least 13 dB in point-to-point configurations with a margin
of more than 70 mVpp with respect to the specified 100 mVpp noise.
