... Combi-terminals (e.g. telephone and answering machine or FAX) Modems and base units of cordless telephones. GENERAL DESCRIPTION The PCA1070 is a CMOS integrated circuit performing all speech and line interface functions in fully electronic telephone sets. The device requires a minimum of external components. The transmission parameters are ...

... All values in the Chapter “Functional description” are typical unless stated otherwise. Line interface DC VOLTAGE DROP Power for the PCA1070 and its peripheral circuits is obtained from the telephone line. The IC develops its own supply voltage at V and regulates its DC voltage drop DD between pins SLPE and V ...

... It should be noted that the AC impedance into pin LN is reduced considerably when DST = 1. Power control I PCA1070 NTERNAL RESET The PCA1070 has an internal reset circuit that monitors the supply voltage below the threshold level DD DD (1.2 V) then the circuit is in reset-mode. In this mode the current consumption is low and the internal reset is active and writes the default values into all registers ...

... After hook-on V decreases and the output RMC will VMC change from logic 0 to logic 1 when V threshold level, however the PCA1070 will stay in the normal operating mode until the internal reset at 1.2 V takes place. By decreasing V the internal reset signal will change ...

... V SS (b) Fig.5 Microphone arrangements. DTMF channel The PCA1070 has an asymmetrical DTMF input. Its input impedance is 200 and its gain is default at 21 dB. DTMF signals can be sent to the line by setting control bit ‘Sending Mute’ (SM) to logic 1 (default SM = 0); by setting ‘Receiving Mute’ (RM) also to logic 1 (default RM = 0), the dialling tones are also sent to the receiving output to generate a confidence tone in the earpiece ...

... All functions can be accessed by writing an 8-bit word to the PCA1070. In order to set up the PCA1070, a control message consisting of the device address, a R/W bit, a subaddress byte and one or more data bytes must be written to the PCA1070. If more than one data byte follows the subaddress, these bytes are stored in the successive registers by the automatic increment feature ...
