U3810BM
Multi Standard Feature Phone Integrated Circuit
Description
The U3810BM multi-standard feature phone circuit is
designed 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.
