V14-V10
A 5 bit coefficient (X) written into this register allows to programme both the tone ringer
attenuation in pulse density mode and the attenuation of the tone generator in square
wave mode. The coefficient in decimal format for a given attenuation can be calculated
as:
X
=
31*10^(

(

)

VOUT
=

20) (V)
In tone generator square wave mode a 4-bit coefficient using bits V13 to V10 allows to
programme the volume where coefficient in decimal format for a given volume can be
calculated as:
X
=
16*10^(
Volume
(
dB
)
20
In receive direction the absolute output value on the speaker and earpiece outputs
depends on AGR and V2.
);X= ( 1…31)
);X= (0…15)
VOUTEP= 6.14 dBm + V2C + V1 + AGR
(dBm)
VOUTSP=6.14 dBm + V2 + V1 + 3 dB
(dBm)
In transmit direction the output value depends on V1 and DGX.
VOUT = 6.14 dBm0 + V1 + DGX
(dBm0)
These bits are the two most significant bits of the 10-bit frequency coefficient.

A 10-bit coefficient (X) written into this register and into bits D0 and D1 of V2 allows to
programme the second frequency from 3.9 Hz to 3996 Hz. The coefficient in decimal
format for a given frequency can be calculated as:
