Receive Gain (GRX)

00h: Stop any received signal to reach the VFRO0 analog output. In order to open the impedance synthesis

feedback it’s necessary to mute the RX analog amplifier, as well.

>00h: Digital gain is inserted in the RX path equal to:

20Log[prog.value/32768]

The prog. value must be espressed in 16 bits signed format: maximum prog. value is equal to 7FFFh.

Transmit Gain (GTX)

00h:

Stop any transmit signal, null level is transmitted in the corresponding timeslot on DX output.

>00h: Digital gain is inserted in the TX path equal to:

20Log[prog.value/32768]

The prog. value must be espressed in 16 bits signed format: maximum prog. value is equal to 7FFFh.

R Filter Coefficient (RFC)

The register is used to set the 17 coefficients (each of 16 bits) of the R filter of the channel #n.

X Filter Coefficient (XFC)

The register is used to set the 17 coefficients (each of 16 bits) of the X filter of the channel #n.
