Register BCR4:
Register TSTR4:
Register LMCR1: TEST-EN = 1
This setting results in a receive gain of 11.88 dB caused by the internal filters. Based on
this, a factor K

To prevent overloading the analog input, the maximum AC transversal current may not
be higher than 9 mA rms.
Usage of Tone Generator as Signal Source
To simplify the formulas, the programmable receive and transmit gain is disabled.
This is done by setting the following bits:
Register BCR4:
Register TSTR4:
Register LMCR1: TEST-EN = 1
The tone generator level is influenced by a factor K
coefficients. The internal filter attenuation is 2.87 dB.
