Loopback Register (LOOPB)
Addr=2Ah; Reset Value=00h
DL3..0=0: Normal Operation
DL3..0=1: Codec #3..0 is set in Digital Loopback mode, this means that the receive PCM signal applied to the
programmed Receive Time Slot is transferred to the programmed Transmit Time Slot.
AL3..0=0: Normal Operation
AL3..0=1: Codec #3..0 is set in Analog Loopback mode, this means that the VFRO signal is transferred to the
VFXI input internally into the Codec.
When loopbacks are enabled the signal appears also at the corresponding VFRO output. It is possible to have
no signal on the VFRO output programming the GRX command to 00h in case of digital loopback.
Transmit Preamplifier Gain Register (TXG)
Addr=2Bh; Reset Value=00h
TG3..0=0: Transmit preamplifier gain ch. 3..0 = 0dB
TG3..0=1: Transmit preamplifier gain ch. 3..0 = 3.52dB
Overall transmit gain depends on combination of TXG and GTXn registers.
Receive Amplifier Gain Register (RXG)
Addr=2Ch; Reset Value=00h
Rn
0
=0,Rn
1
=0: Receive amp. gain ch #n = mute
Rn
0
=1,Rn
1
=0: Receive amp. gain ch #n = -12dB
Rn
0
=0,Rn
1
=1: Receive amp. gain ch #n = -6dB
Rn
0
=1,Rn
1
=1: Receive amp. gain ch #n = 0dB
Overall receive gain depends on the receive amplifier gain (R3..0) setting in RXG reg. and digital gain (GRXn
reg. setting).
