Table 1
Transducer Interfaces
Standard handset transducer interfaces are provided by the MT91L60/61. These are:
The handset microphone inputs (transmitter), pins M+/M-. The nominal transmit path gain may be adjusted
to either 6.0 dB or 15.3 dB. Control of this gain is provided by the TxINC control bit (Gain Control register 1,
address 00h).
The handset speaker outputs (receiver), pins HSPKR+/HSPKR-.This internally compensated fully
differential output driver is capable of driving the load shown in Figure 3. The nominal receive path gain may
be adjusted to either 0 dB, -6 dB or -12 dB. Control of this gain is provided by the RxINC control bit (Gain
Control register 1, address 00h). This gain adjustment is in addition to the programmable gain provided by
the receive filter.
