GENERAL DESCRIPTION

The TEA1114A is a bipolar integrated circuit that performs
all speech and line interface functions required in fully
electronic telephone sets. It performs electronic switching
between speech and dialling. The IC operates at a line
voltage down to 1.45 V DC (with reduced performance) to
facilitate the use of telephone sets connected in parallel.

When the line current is high enough, a fixed amount of
current is derived from the LN pin in order to create a
strong supply point at pin VDD. The voltage at pin VDD is
regulated to 3.3 V to supply peripherals such as dialler,
LCD module and microcontroller.

FUNCTIONAL DESCRIPTION

All data given in this chapter are typical values, except
when otherwise specified.

Supply (pins LN, SLPE, REG, VCCand VDD)

The supply for the TEA1114A and its peripherals is
obtained from the telephone line (see Fig.3).

T

HE LINE INTERFACE (PINS LN, SLPE AND REG)

The IC generates a stabilized reference voltage (V

ref

)

between pins LN and SLPE. V

ref

is temperature
compensated and can be adjusted by means of an
external resistor (RVA). V

ref

equals 4.15 V and can be
increased by connecting RVA between pins REG and
SLPE or decreased by connecting R

VA

between pins
REG and LN. The voltage at pin REG is used by the
internal regulator to generate V

ref

and is decoupled by

C

REG

, which is connected to VEE. This capacitor,
converted into an equivalent inductance
(see Section “Set impedance”)realizesthesetimpedance
conversion from its DC value (R

SLPE

) to its AC value
(RCCin the audio-frequency range). The voltage at
pin SLPE is proportional to the line current.

The voltage at pin LN is:

where:

I

line

= line current
ICC= current consumption of the IC
IP= supply current for external circuits
I

SUP

= current consumed between LN and VEE by the

VDD regulator.

Thepreferredvalue for R

SLPE

is 20 Ω.ChangingR

SLPE

will
affect more than the DC characteristics; it also influences
the microphone and DTMF gains, the gain control
characteristics, the sidetone level and the maximum
output swing on the line.

The DC line current flowing into the set is determined by
the exchange supply voltage (V

EXCH

), the feeding bridge

resistance (R

EXCH

), the DC resistance of the telephone

line (R

line

) and the reference voltage (V

ref

). With line
currents below 9 mA, the internal reference voltage
(generatingV

ref

)isautomatically adjusted to a lower value.
This means that more sets can operate in parallel with
DC line voltages (excluding the polarity guard) down to an
absolute minimum voltage of 1.45 V. At currents below
9 mA, the circuit has limited sending and receiving levels.
This is called the low voltage area.

THE INTERNAL SUPPLY POINT (PIN VCC)
The internal circuitry of the TEA1114A is supplied from

pin V

CC

. This voltage supply is derived from the line

voltage by means of a resistor (R

CC

) and must be

decoupled by a capacitor C

VCC

. It may also be used to

supply some external circuits. The V

voltage depends

on the current consumed by the IC and the peripheral
circuits as:

THE REGULATED SUPPLY POINT (PIN VDD)
The V

DD

regulator delivers a stabilized voltage for the
peripherals in transmission mode (nominal VLN) as well as
in ringer mode (VLN= 0 V). The regulator (see Fig.6)
consistsofa sense input circuit, a current switchandaV

DD

output stabilizer. The regulator operates as a current
source at the LN input in transmission mode; it takes a
constant current of 4.3 mA (at nominal conditions) from
pin LN. The current switch reduces the distortion on the
line at large signal swings. Output VDD follows the
DC voltage at pin LN (with typically 0.35 V difference) up
to VDD= 3.3 V. The input current of the regulator is
constantwhiletheoutput(source)currentis determined by
the consumption of the peripherals. The difference
betweeninputand output current is shunted bytheinternal
V

DD

stabilizer.

Inringer mode, the stabilizer operates as ashunt stabilizer
to keep V

DD

at 3.3 V. In this mode, the input voltage
VLN= 0 V while the input current into pin VDD is delivered
by the ringing signal. VDD has to be decoupled by a
capacitor C

VDD

.

Set impedance

In the audio frequency range, the dynamic impedance is
mainly determined by the RCC resistor. The equivalent
impedance of the circuit is illustrated in Fig.7.

Transmit stage (pins MIC+, MIC− and DTMF)

MICROPHONE AMPLIFIER (PINS MIC+ AND MIC−)
The TEA1114A has symmetrical microphone inputs.

The input impedance between pins MIC+ and MIC− is
64 kΩ (2 × 32 kΩ). Thevoltage gain from pins MIC+/MIC−
to pin LN is set at 44.2 dB (typically).

Automatic gain control is provided on this amplifier for line
loss compensation.

DTMF AMPLIFIER (PIN DTMF)
When the DTMF amplifier is enabled, dialling tones may

be sent on line. These tones are also sent to the receive
output RX at a low level (confidence tone).

The TEA1114A has an asymmetrical DTMF input.
The input impedance between DTMF and VEE is 20 kΩ.
The voltage gain from pin DTMF to pin LN is set at 26 dB.

Automatic gain control has no effect on the DTMF
amplifier.

TEA1114A

Receiving stage (pins IR, RX, GAR and QR)

The receive part consists of a receive amplifier and an
earpiece amplifier.

THE RECEIVE AMPLIFIER (PINS IR AND RX)
The receive amplifier transfers the receive signal from

input IR to output RX. The input impedance of the receive
amplifier, between pins IR and VEE,is20kΩ. The voltage
gain from pin IR to RX is set at 33.4 dB. RX output is
intended to drive high ohmic (real) loads. Automatic gain
control is provided on the receive amplifier.

THE EARPIECE AMPLIFIER (PINS GAR AND QR)
The earpiece amplifier is an operational amplifier having

its output (QR) and inverting input (GAR) available. It can
be used in conjunction with two resistors to get someextra
gain or attenuation.

In an usual configuration (see Fig.8), output RX drives the
earpiece amplifier by means of RE1 connected between
RX and GAR. Feedback resistor RE2 of the earpiece
amplifier is connected between QR and GAR. Output QR
drives the earpiece.

The gain of the earpiece amplifier (from RX to QR) can be
set between +12 and −14 dB by means of resistor RE2.

The preferred value of RE1 is 100 kΩ.
The earpiece amplifier offers a gain boost facility relative

to the initial gain. Resistor RE2 has to be replaced by the
network of R

E21

, R

E22

and R

E23

as shown in Fig.8.
The initial gain is defined by:
which corresponds to R

E23

= ∞. The gain boost is realized

by a defined value of R

E23

and is:

Two external capacitors C

GAR

(connected between GAR

and QR) and C

GARS

(connected between GAR and VEE)

ensure stability. The C

GAR

capacitor provides a first-order
low-pass filter. The cut-off frequency corresponds to the
time constant C

GAR

× RE2. The relationship

C

GARS

=10×C

GAR

must be fulfilled to ensure stability.

The output voltages of both amplifiers are specified for
continuous wave drive. The maximum output swing
depends on the DC line voltage V

LN

, the RCCresistor, the
ICC current consumption of the circuit, the IP current
consumption of the peripheral circuits and the load
impedance.

TEA1114A

Automatic gain control (pin AGC)

The TEA1114A performs automatic line loss
compensation. The automatic gain control varies the gain
of the microphone amplifier and the gain of the receive
amplifier in accordance with the DC line current.

The control range is 6.0 dB (which corresponds
approximately to a line length of 5 km for a 0.5 mm
diametertwisted-pair copper cable with a DC resistanceof
176 Ω/km and an average attenuation of 1.2 dB/km).

The ICcan be used withdifferent configurations of feeding
bridge (supply voltage and bridge resistance) by
connecting an external resistor R

AGC

between pins

AGC and VEE. This resistor enables the I

start

and I

stop

line

currents to be increased(the ratio between I

start

and I

stop

is
not affected by the resistor). The AGC function is disabled
when pin AGC is left open-circuit.

Mute function (pin MUTE)

The mute function performs the switching between the
speech mode and the dialling mode.

When MUTE is LOW, the DTMF input is enabled and the
microphone and receive amplifier inputs are disabled.
In this mode, the DTMF tones are sent to the receive
output at a low level (confidence tone).

When MUTE is HIGH, the microphone and receiving
amplifiers inputs are enabled while the DTMF input is
disabled. The MUTE input is provided with an internal
pull-up current source to VCC.

line

, R

, R

, R

and Z

(see Fig.9)
suppresses the transmitted signal in the earpiece.
Maximum compensation is obtained when the following
conditions are fulfilled:

The scale factor k is chosen to meet the compatibility with
a standard capacitor from the E6 or E12 range for Z

bal

.

In practice, Z

line

varies considerably with the line type and

thelinelength. Therefore, the value of Z

bal

shouldbefor an
average line length which gives satisfactory sidetone
suppression with short and long lines. The suppression
also depends on the accuracy of the match between Z

bal

and the impedance of the average line.
The anti-sidetone network for the TEA1114A attenuates

the receiving signal from the line by 32 dB before it enters
the receiving amplifier. The attenuation is almost constant
over the whole audio frequency range.

A Wheatstone bridge configuration (see Fig.10) may also
be used.

More information on the balancing of an anti-sidetone
bridgecan be obtained inour publication

SOLDERING
Introduction

Thistextgives a very brief insight to acomplextechnology.
A more in-depth account of soldering ICs can be found in
our

“Data Handbook IC26; Integrated Circuit Packages”

(document order number 9398 652 90011).
There is no soldering method that is ideal for all IC

packages. Wave soldering is often preferred when
through-holeandsurfacemountcomponentsaremixedon
one printed-circuit board. However, wave soldering is not
always suitable for surfacemount ICs, orfor printed-circuit
boards with high population densities. In these situations
reflow soldering is often used.

Through-hole mount packages

SOLDERING BY DIPPING OR BY SOLDER WAVE
The maximum permissible temperature of the solder is

260 °C; solder at this temperature must not be in contact
with the joints for more than 5 seconds. The total contact
time of successive solder waves must not exceed
5 seconds.

The device may be mounted up to the seating plane, but
the temperature of the plastic body must not exceed the
specified maximum storage temperature (T

stg(max)

). If the
printed-circuit board has been pre-heated, forced cooling
may be necessary immediately after soldering to keep the
temperature within the permissible limit.

MANUAL SOLDERING
Apply the soldering iron (24 V or less) to the lead(s) of the

package, either below the seating plane or not more than
2 mm above it. If the temperature of the soldering iron bit
is less than 300 °C it may remain in contact for up to
10 seconds. If the bit temperature is between
300 and 400 °C, contact may be up to 5 seconds.

Surface mount packages

REFLOW SOLDERING
Reflow soldering requires solder paste (a suspension of

fine solder particles, flux and binding agent) to be applied
tothe printed-circuit board by screenprinting,stencilling or
pressure-syringe dispensing before package placement.

Several methods exist for reflowing; for example,
infrared/convection heating in a conveyor type oven.
Throughput times (preheating, soldering and cooling) vary
between 100 and 200 seconds depending on heating
method.

Typical reflow peak temperatures range from
215 to 250 °C. The top-surface temperature of the
packages should preferable be kept below 230 °C.

WAVE SOLDERING
Conventional single wave soldering is not recommended

forsurfacemountdevices (SMDs) or printed-circuit boards
with a high component density, as solder bridging and
non-wetting can present major problems.

To overcome these problems the double-wave soldering
method was specifically developed.

If wave soldering is used the following conditions must be
observed for optimal results:

• Use a double-wave soldering method comprising a
turbulent wave with high upward pressure followed by a
smooth laminar wave.

• For packages with leads on two sides and a pitch (e):
– larger than or equal to 1.27 mm, the footprint

longitudinal axis is preferred to be parallel to the
transport direction of the printed-circuit board;

– smaller than 1.27 mm, the footprint longitudinal axis

must be parallel to the transport direction of the
printed-circuit board.

The footprint must incorporate solder thieves at the
downstream end.

• Forpackageswithleads on four sides, the footprint must
be placed at a 45° angle to the transport direction of the
printed-circuit board. The footprint must incorporate
solder thieves downstream and at the side corners.

During placement and before soldering, thepackage must
be fixed with a droplet of adhesive. The adhesive can be
applied by screen printing, pin transfer or syringe
dispensing. The package can be soldered after the
adhesive is cured.

Typical dwell time is 4 seconds at 250 °C.
A mildly-activated flux will eliminate the need for removal
of corrosive residues in most applications.

MANUAL SOLDERING
Fix the component by first soldering two

diagonally-opposite end leads. Use a low voltage (24 V or
less) soldering iron applied to the flat part of the lead.
Contact time must be limited to 10 seconds at up to
300 °C. When using a dedicated tool, all other leads can
be soldered in one operation within 2 to 5 seconds
between 270 and 320 °C.

Suitability of IC packages for wave, reflow and dipping soldering methods

Notes

1. All surface mount (SMD) packages are moisture sensitive. Depending upon the moisture content, the maximum
temperature (with respect to time) and body size of the package, there is a risk that internal or external package
cracks may occur due to vaporization of the moisture in them (the so called popcorn effect). For details, refer to the
Drypack information in the

“Data Handbook IC26; Integrated Circuit Packages; Section: Packing Methods”

.

2. For SDIP packages, the longitudinal axis must be parallel to the transport direction of the printed-circuit board.

3. These packages are not suitable for wave soldering as a solder joint between the printed-circuit board and heatsink
(at bottom version) can not be achieved, and as solder may stick to the heatsink (on top version).

4. If wave soldering is considered, then the package must be placed at a 45° angle to the solder wave direction.
The package footprint must incorporate solder thieves downstream and at the side corners.

5. Wave soldering is only suitable for LQFP, QFP and TQFP packages with a pitch (e) equal to or larger than 0.8 mm;
it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.65 mm.

6. Wave soldering is only suitable for SSOP and TSSOP packages with a pitch (e) equal to or larger than 0.65 mm; it is
definitely not suitable for packages with a pitch (e) equal to or smaller than 0.5 mm.
