TX
The TX and RX audio signal paths have a programmable gain block. If a TX or RX voltage gain other than the nominal
power-up default is desired it can be programmed via the microcontroller interface.
The gain blocks can be used during final test of the telephone to electronically adjust for gain tolerances in the telephone
system. The RX gain and the TX gain selection covers a dynamic range from 7.5 to +8 dB in steps of 0.5 dB and can
be programmed independently from each other.
