UNIVERSAL SPEECH

CIRCUIT

integrated speech circuits for using in electronic telephones.

Transmitting and receiving gain are regulated with line length.

Different regulation for various current feeds can be set by

external resistors. Typical current feeds as 48V 2·200Ω, 48V,

2·400Ω, and 36V, 2·500Ω, can be handled. Application

dependent parameters such as line balance, side tone level,

amplification and frequency response are set by external

components. Parameters are set independently which means

easy adaptation for various market needs.

ICs. A separate DTMF input is switched when the circuit is

muted, and an adjustable DC supply is provided for feeding an

external CMOS device.

*Minimum number of inexpensive external components, 5

*Mute function for operation with DTMF-generator.

*Transmit and receive gain regulation for automatic loop loss

*Short start-up time.

*Stabilized DC-supply for low current CMOS dialers and/or

*DTMF-input controlled by mute.
