is determined by the selected telecom codec sample rate. This voice band filter is activated by setting TEL_VOICE_ENA
in the telecom control register B. The resulting telecom input filter curves are given in Fig.38 and Fig.39.
The output section of the telecom codec is designed to interface with a 600
line through an isolation transformer. The
built-in mute function is activated by TEL_MUTE in the telecom control register B. The output driver remains active in the
mute mode, however no output signal is produced. Loading the drivers with a capacitive load may cause high frequency
oscillations and should be done cautiously.
