U3810BM General Description
The U3810BM multi-standard feature phone circuit isdesigned to be used with a microcontroller using a 2-wire serial bus. It performs all speech and line interface functions required in an electronic telephone set: the ringing function with switching regulator and melody generator, the DTMF dialling, the loudhearing with antilarsen and antidistortion systems, a power supply, a clock and a reset for the microcontroller. Transmit, receive and loudhearing gains control / AGC range / DTMF frequencies, pre-emphasis and level / melody generator, and mutes are programmable through the serial bus.
