FUNCTIONAL DESCRIPTION
Speech part
For numbering of components refer to Figs 28 and 29.
SUPPLIES VCC, LN, SLPE, REG AND STAB
Power for the IC and its peripheral circuits is usually
obtained from the telephone line (see Fig.4).
The circuit creates a stabilized voltage (Vref = 3.7 V)
between LN and SLPE. This reference voltage is
temperature compensated and can be adjusted by means
of an external resistor RVA. It can be increased by
connecting an RVA resistor (R60) between REG and SLPE
or decreased by connecting an RVA resistor (R61)
between REG and LN. This internal voltage reference is
decoupled by capacitor C3 between REG and VEE.
This decoupling capacitor realises the set impedance
conversion from its DC value to its AC value in the audio
frequency range.
The internal transmission part of the circuitry (including the
earpiece amplifier) is supplied from VCC. This voltage
supply is derived from the LN voltage via a dropping
resistor (R1) and must be decoupled by a capacitor (C1)
between VCC and VEE. This supply point may also be used
to supply the dialler/ringer (VDD) part or external circuit e.g.
electret microphone.
The DC current flowing into the set is determined by the
exchange supply voltage Vexch, the feeding bridge
resistance Rexch and the DC resistance of the telephone
line Rline. When the line current (Iline) is more than 0.5 mA
greater than the sum of the IC supply current (ICC) and the
current drawn by the peripheral circuitry connected to VCC
(Ip), the excess current is shunted to SLPE via LN.
