U3500BM Cordless Telephone Signal Processor Description The programmable cordless phone signal processor includes all necessary low frequency parts such as microphone- and earphone amplifier, compander, preemphasis, deemphasis, scrambler, data management, power-supply management, as well as RF receiving parts such as IF converter, FM demodulator. RSSI and low noise amplifier. Several gains and mutes in transmit and receive direction are controlled by serial bus while compander, pre- and deemphasis and scrambler can be bypassed.
