Attenuation Distortion
The signal attenuation in either path is nominally independent of the frequency. The deviations from nominal attenuation will stay
within the limits shown in Figure 1 and Figure 2. The reference frequency is 1014 Hz and the signal level is
= 3300 Hz, f
The End-to-End Group Delay is the sum of the transmit and receive group delays (both measured using the same time and clock slot).
Typical values not tested in production.
