The main power supply will be provided through a double connection. These connections are respectively the pin 3 and 4 for the +5V and the pins 1 and 2 for the ground (GND). The power supply is 5V +/-5% 1A.
3.2.2 Serial Link RS232
This interface is needed for communication with a remote terminal with respect to the RS232 V.28 standard levels. As the integ rated modem does not include a transceiver MAX3238 or MAX3237, this one has to be added outside with a SUBD9. The conn ection between t he WMOi3 and the tr ansceiver must not exceed 10 cm. The table below lists the needed signals for this inte rface :

3.2.4.2 Microphone 1
The MIC1 inputs are differential and do not include internal bias. To use these inputs with an electret microphone, bias has to be generated outside the WMOI3 modem according to the characteristic of this electret microphone. These inputs are the standard ones used for an external headset or a handsfree kit. The connection can be either differential or single-ended but using a differential co nnection in order to reje ct common mode noise and TDM A noise is recommended. When using a single-ended connection, be sure to have a very good ground plane, a very good filtering as well as shielding in order to avoid any disturbance on the audio path.
The gain of MIC1 inputs is internally adjusted. The gain can be tuned from 30dB to 51dB.

Speaker outputs SP K2 are push-pull amplif iers and can be loaded down to 50 Ohms and up to 1nF. These outputs are differential and the output power can be adjusted by step of 2dB. The output can be directly connected to a speaker. The connection can be differential or single-ended but using a differential connection to reject common mode noise and TDMA noise is recommended. When using a single-ended connection, be sure to have a very good ground plane, a very good filtering as well as shielding in order to avoid any disturbance on the audio path.
