AMU=0 µ Law selected.
AMU=1 A Law selected.
VFXI input must be AC coupled to the signal source; the voltage swing allowed is 1.0Vpp
when the preamplifier gain is set 0dB or 0.66Vpp if the gain is set to 3.52dB (MCU mode
only); higher levels must be reduced through proper dividers.
Typical impedance of VFXI input is 1Mohm.

Receive path
The received PCM signal DR through the decoder section, the gain select block and the D/A
converter is converted in an analog signal which is transferred to VFRO output through an
amplifier stage.
