The KKA1062 and KKA1062A are integrated circuits that perform all speech and line interface functions required in fully
electronic telephone sets. They perform electronic switching between dialing and speech. The ICs operates at line voltage down
to 1.6 V DC (with reduced performance) to facilitate the use of more telephone sets connected in parallel.
All statements and values refer to all versions unless otherwise specified. The KKA1062 (KKA1062A) is packaged in a standard
16-pin plastic DIP and special plastic DIP with internal heatsink is also available.

Automatic line loss compensation is achieved by connecting a
resistor (R6) between AGC and VEE.
The automatic gain control varies the gain of the microphone
amplifier and the receiving amplifier in accordance with the DC line
current. The control range is 5.8 dB which corresponds to a line
length of 5 km for a
0.5mm diameter twisted-pair copper cable with a DC resistance of
176 ?/km and average attenuation of
1.2dB/km. Resistor R6 should be chosen in accordance with the
exchange supply voltage and its feeding bridge resistance. The ratio
of start and stop currents of the AGC curve is independent of the
value of R6. If no automatic
line-loss compensation is required the AGC pin may be left open-
circuit. The amplifiers, in this condition, will give their maximum
specified gain.
Sidetone suppression
The anti-sidetone network, R1//Zline, R2, R3, R8, R9 and Zbal
suppresses the transmitted signal in the earpiece. Maximum
compensation is obtained when the following conditions are fulfilled:
⎛ R 8 x ⎞Zbal
R9 x R2 = R1 x R 3 + ⎝⎜ R 8 + Zbal ⎠⎟
(1)
Zbal
Zline
=
Zbal + R 8 Zline+ R 1
KKA1062/1062A
(2)
If fixed values are chosen for R1, R2, R3 and R9, then condition (1)
will always be fulfilled when
To obtain optimum sidetone suppression, condition (2) has to be
fulfilled which results in:
R8
Zbal =
x Zline = k x Zline
R1
R8
Where k is scale factor; k =
R1
The scale factor k, dependent on the value of R8, is chosen to meet
the following criteria:
- compatibility with a standard capacitor from the E6 or
E12 range for Zbal
- |Zbal//R8|<<R8 fulfilling condition (a) and thus
ensuring correct
anti-sidetone bridge operation
- |Zbal + R8|>>R9 to avoid influencing the transmit gain.
In practise Zline varies considerably with the line type and length. The
value chosen for Zbal should therefore be for an average line thus
giving optimum setting for short or long lines.
