INTEGRATED CIRCUITS DATA SHEET TEA1083; TEA1083A Call progress monitor for line powered telephone sets Product specification File under Integrated circuits, IC03A March 1994 Philips Semiconductors Product specification Call progress monitor for line powered telephone sets TEA1083; TEA1083A a loudspeaker during on-hook dialling. The TEA1083/83A is intended for use in conjunction with a transmission circuit of the TEA1060 family. The device uses a part of the available line current via the internal supply circuit. The loudspeaker amplifier, which consists of a preamplifier and a power amplifier, amplifies the received line signals from the transmission circuit when enabled via the LSE input. The loudspeaker amplifier can also be used to amplify dialling tones from the dialler IC. The power amplifier contains a push-pull output stage to drive the loudspeaker in a Single Ended Load (SEL) configuration. The internal voltage stabilizer can be used to supply external devices. By activating the power-down (PD) input of the TEA1083A, the current consumption of the circuit will be reduced, this enables pulse dialling or flash (register recall). An internal start circuit ensures normal start-up of the transmission IC. FEATURES • Internal supply – Optimum current split-up – Low constant current (adjustable) in transmission IC – Nearly all line current available for monitoring – Stabilized supply voltage • Loudspeaker amplifier with a fixed gain of 35 dB • Volume controlled by potentiometer • Power-down input (TEA1083A only) • Loudspeaker enable input.

A call progress monitor is recommended by the European Telecommunications Standards Institute (ETSI) for telephone sets with automatic on-hook dialling facilities so that audible, or visual, progress of a call attempt can be monitored. In accordance with the ETSI (at a frequency of 440 Hz and a line level of 20 dBm (600 Ω)), a minimum level of 50 dBA shall be guaranteed at a distance of 50 cm from the set. This corresponds to a minimum level of approximately 100 mV (RMS) (PO ≥ 0.2 mW) across a loudspeaker; Philips type AD2071/Z50. The TEA1083/83A is normally used in conjunction with a transmission circuit of the TEA1060 family. The circuit must be connected between the positive line terminal (pin 2) and pin SLPE of the transmission IC. The transmission characteristics (impedance, gain settings, etc.) are not affected. An interconnection between the TEA1083/83A and a member of the TEA1060 family is illustrated in Fig.5. Supplies SUP, SREF, VBB and VSS In Fig.6 the line current is divided into ITR for the transmission IC and ISUP for the monitoring circuit TEA1083/83A. A listening-in set has to offer the user more facilities e.g. howling limiting to reduce annoying loudspeaker and line signals. Dynamic limiting of the loudspeaker signal, with respect to supply conditions, can also be required. Acoustic output levels for listening-in sets are approximately 70 to 75 dBA. This corresponds to a loudspeaker level of approximately 1 mV (RMS) (PO ≈ 20 mW). ITR is constant: ITR = Vint / R20 ISUP = Iline − ICC − ITR Where: 2. The MUTE function of the TEA1085A has a logic input; the MUTE function of the TEA1085 has a toggle input. • Vint is an internal temperature compensated reference voltage of 500 mV (typ) between pins SUP and SREF 3. SEL: loudspeaker connected in a single-ended-load configuration BTL: loudspeaker connected in a bridge-tied-load configuration • R20 is a resistor connected between SUP and SREF • ICC is the internal current consumption of the TEA106X (approximately 1 mA). A practical value for resistor R20 is 150 Ω; this produces a current of approximately 3.3 mA (typ) for ITR and ISUP is approximately equal to Iline − 4.3 mA. 4. Consult the product specification for the package outline/s. March 1994 5 Philips Semiconductors Product specification Call progress monitor for line powered telephone sets The circuit stabilizes its own supply voltage at VBB. Transistor TR1 provides the supplies for the internal circuits. Transistor TR2 is used to minimize signal distortion on the line by momentarily diverting the input current to VSS whenever the instantaneous value of the voltage at VSUP drops below the supply voltage VBB. VBB is fixed to a typical value of 2.95 V. The supply at VBB is decoupled with respect to VSS by a 220 µF capacitor (C20). The maximum voltage swing at the QLS output is VO(p-p) = 2.5 V (typical with 50 Ω load). The input level VLSI is approximately 16 mV(rms) and the supply current ISUP > 11 mA. In this condition the signal is limited by the available voltage space (VBB). Higher input levels and/or lower supply currents will result in an increase of the harmonic distortion due to signal clipping. With a limit of 2.5 V (p-p), the maximum output swing is dependent on the supply current and loudspeaker impedance. It can be approximated, for low distortions, by the following equation: The DC voltage (VSUP − VSS) is determined by the transmission IC and Vint; thus VSUP − VSS = VLN−SLPE + Vint. The reference voltage of the transmission IC has to be adjusted to a level where VSUP − VBB (max) is greater than 400 mV. The minimum voltage space between SUP and VBB (400 mV) is required to maintain a 'high' efficiency of the internal supply for mean speech levels. VBB (max) is the specified maximum level. VO(p-p) = 2 × (ISUP − ISUPO) × π × RLS Where; • VO(p-p) = the peak-to-peak level of the loudspeaker • RLS = the loudspeaker impedance • ISUPO = 2.5 mA (typ.) The internal current consumption of the TEA1083/83A (ISUP0) is typically 2.5 mA (where VSUP − VSS = 3.6 V). The current ISUP0 consists of currents IBIAS (approximately 0.4 mA) for the circuitry connected to SUP and IBB0 (approximately 2.1 mA) for the internal circuitry connected to VBB (see Fig.6). POWER-DOWN INPUT (PD) During pulse dialling or register recall (timed loop break) the telephone line is interrupted, thereby breaking the supply current to the transmission IC. The capacitor connected to VBB provides the supply for the TEA1083/83A during the supply breaks. LOUDSPEAKER AMPLIFIER (LSI1/LSI2 and QLS) By making the PD input HIGH during the loop break, the requirement on the capacitor is eased and, consequently, the internal current consumption IBB0 (see Fig.5) is reduced from 2.1 mA to 400 µA typically. Transistors TR1 and TR2 are inhibited during power-down and the bias current is reduced from approximately 400 µA to approximately 50 µA with VSUP = 3.6 V in the following equation: The TEA1083/83A has symmetrical inputs at LSI1 and LSI2. The input signal is normally taken from the earpiece output of the transmission circuit (see Fig.5) and/or from the signal output of the DTMF generator via a resistive attenuator. The attenuation factor must be chosen in accordance with the output levels from the transmission IC and/or DTMF generator and, in accordance with the required output power and permitted signal distortion from the loudspeaker signal. ISUP(PD) = IBIAS(PD) = (VSUP − 2Vd)/Ra Where 3.6 < VSUP < VBB + 3 V 2Vd is the voltage drop across 2 internal diodes (approximately 1.3 V) The output QLS drives the loudspeaker as a single-ended load. The output stage has been optimized for use with a 50 Ω loudspeaker (e.g. Philips type AD2071). The loudspeaker amplifier is enabled when the LSE input goes HIGH. The gain of the amplifier is fixed at 35 dB. Ra is an internal resistor (typical 50 kΩ) LOUDSPEAKER ENABLE INPUT (LSE) Volume control of the loudspeaker signal can be obtained by using a level control at the input (see Fig.5). March 1994 TEA1083; TEA1083A The LSE input has a pull-down structure. It switches the loudspeaker amplifier, in the monitoring condition, by applying a HIGH level at the input. The amplifier is in the standby condition when LSE is LOW (input open-circuit or connected to VSS). 6 Philips Semiconductors Product specification Call progress monitor for line powered telephone sets TEA1083; TEA1083A handbook, full pagewidth VCC LN SREF MIC PD QR LSE TEA106x IR line VEE TEA1083 QLS TEA1083A LSI1 SLPE SUP VBB LSI2 VSS MGR049 Fig.5 Interconnection with a transmission IC of the TEA106X family. handbook, full pagewidth Iline ISUP VSUP ICC R1 ITR SUP R20 TR2 Vint VCC IBBO LN TR1/TR2 CONTROL TEA1083 TEA1083A line SLPE IBIAS C1 C28 VSS SLPE R9 VEE Fig.6 Supply arrangement.

Dwell times vary between 50 and 300 seconds depending on heating method. Typical reflow temperatures range from 215 to 250 °C. SOLDERING Introduction There is no soldering method that is ideal for all IC packages. Wave soldering is often preferred when through-hole and surface mounted components are mixed on one printed-circuit board. However, wave soldering is not always suitable for surface mounted ICs, or for printed-circuits with high population densities. In these situations reflow soldering is often used. Preheating is necessary to dry the paste and evaporate the binding agent. Preheating duration: 45 minutes at 45 °C. WAVE SOLDERING This text gives a very brief insight to a complex technology. A more in-depth account of soldering ICs can be found in our “Data Handbook IC26; Integrated Circuit Packages” (order code 9398 652 90011). Wave soldering techniques can be used for all SO packages if the following conditions are observed: • A double-wave (a turbulent wave with high upward pressure followed by a smooth laminar wave) soldering technique should be used. DIP • The longitudinal axis of the package footprint must be parallel to the solder flow. SOLDERING BY DIPPING OR BY WAVE The maximum permissible temperature of the solder is 260 °C; solder at this temperature must not be in contact with the joint for more than 5 seconds. The total contact time of successive solder waves must not exceed 5 seconds. • The package footprint must incorporate solder thieves at the downstream end. During placement and before soldering, the package 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. 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 (Tstg 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. Maximum permissible solder temperature is 260 °C, and maximum duration of package immersion in solder is 10 seconds, if cooled to less than 150 °C within 6 seconds. Typical dwell time is 4 seconds at 250 °C. REPAIRING SOLDERED JOINTS A mildly-activated flux will eliminate the need for removal of corrosive residues in most applications. Apply a low voltage soldering iron (less than 24 V) to the lead(s) of the package, 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. REPAIRING SOLDERED JOINTS Fix the component by first soldering two diagonallyopposite end leads. Use only a low voltage soldering iron (less than 24 V) 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. SO REFLOW SOLDERING Reflow soldering techniques are suitable for all SO packages. Reflow soldering requires solder paste (a suspension of fine solder particles, flux and binding agent) to be applied to the printed-circuit board by screen printing, stencilling or pressure-syringe dispensing before package placement.
