7 7.1 FUNCTIONAL DESCRIPTION (see Fig.1) Supply pins (VDD and VSS) 7.4
PCD3360
Frequency discriminator circuit (FDE and FDI)
If the supply current (VDD) drops below the standby voltage (Vstb), the oscillator and most other functions are switched off and the supply current is reduced to the standby current (Istb). The automatic swell register retains its information until VDD drops further to a value VAS at which reset occurs. 7.2 Oscillator (OSC)
The frequency discriminator circuit prevents the ringer being activated unintentionally by dial pulses, speech or other invalid signals. The circuit is enabled or disabled by input FDE. When FDE is LOW and VDD > Vstb, the circuit is enabled and FDI acts as the input for ringing frequency detection. When FDE is HIGH, the circuit is disabled and FDI becomes the enable/disable input for tone sequence generation. When the circuit is enabled, it starts to produce output ringing tones after one cycle of an appropriate input frequency is detected at FDI. An input cycle is detected when either 2 rising or 2 falling edges are received, and this implies a delay of between 1 and 1.5 input cycles before output ringing begins. The allowed input frequency range is set by the states of pins FL and FH, as shown in Table 2. Output ringing continues for as long as valid input ringing frequency is detected. FDI has a Schmitt-trigger action; the levels are set by an external resistor R2 (see Fig.8) and an internal sink current that is switched from 20 A (typ.) for FDI = LOW to <0.1 A for FDI = HIGH. Excess current entering FDI via R2 is absorbed by internal diodes clamped to VDD and VSS. 7.5 Selection of frequency discriminator limits (FL and FH)
The 64 kHz oscillator is operated via an external resistor and capacitor connected to pin OSC (see Fig.8). The oscillator signal is divided by two to provide the 32 kHz internal system clock. 7.3 Selection pin input circuit (see Fig.3)
Pins FDE, RR1, RR2, DM, IS1, IS2, TS1, TS2, FL and FH are pulled down internally by a pull-down current IIH when they are connected to VDD and by a pull-down resistance RIL when they are connected to VSS. Thus when the pins are open-circuit they are defined LOW. Therefore only a single-contact switch is required to connect the pins to VDD; yet the supply current is only marginally increased as IIH is very small.

7.6 Selection of tone sequences (TS1 and TS2)
PCD3360
TS1 and TS2 are effective when both FDE and FDI are HIGH, and VDD > Vstb. TS1 and TS2 normally select one of the four standard tone sequences shown in Fig.4. Different tone sequences of 15 or 16 consecutive tones and pauses can be mask programmed to order. The seven tones (plus pause) available are shown in Fig.5, together with the corresponding ROM codes. The tone sequences are repeated continuously provided the enable conditions at inputs FDE and FDI are valid and VDD > Vstb. The first sequence and subsequent repetitions always begin with the first note in the sequence.

7.7 Selection of repetition rates (RR1 and RR2) 7.8 Drive mode selection (DM)
PCD3360
The duration of a time interval within a tone sequence is determined by the state of inputs RR1 and RR2 as shown in Table 3. The resultant variation of repetition rates acts as a distinguishing feature between adjacent telephones. Table 3 Duration of time intervals (fOSC = 64 kHz) INPUT STATE RR1 LOW LOW HIGH HIGH RR2 LOW HIGH LOW HIGH TIME INTERVAL (ms) 15 30 45 60
The output signal at pin TONE can be selected for application with electro-dynamic or piezo-electric transducers. An example of both signals, for a tone frequency of 667 Hz, is shown in Fig.6. 7.8.1 LOUDSPEAKER MODE
In the loudspeaker mode (DM = LOW), pin TONE outputs a delta-modulated signal that approximates a sinewave sampled at a rate of 32 kHz. The output pulse duration is determined by pins IS1 and IS2. The resultant acoustic spectrum is aurally more acceptable and has greater penetration than a square-wave spectrum because more power is concentrated at the fundamental frequency. 7.8.2 PXE MODE
The repetition rate variation can be extended by mask programming the same tone combination for all 4 tone sequences, but with a different number of time intervals per tone. Thus the repetition rate can be selected from 16 values by inputs RR1, RR2, TSI and TS2. The single tone sequence used is customer-defined. 7.9
In the PXE mode (DM = HIGH), pin TONE outputs a square wave. In this mode the ringer impedance and sound pressure level are determined by characteristics (e.g. the size) of the PXE transducer; inputs IS1 and IS2 are inactive.
Setting of impedance, sound pressure level and automatic swell (IS1 and IS2)
With DM = LOW (loudspeaker mode), inputs IS1 and IS2 determine the pulse duration of the output signal and thereby the DC resistance Rxy (seen at points x and y in Fig.8), the input impedance Zi and also the Sound Pressure Level (SPL). The selection of 3 impedance settings and automatic swell is shown in Table 4. Table 4 Setting of pulse duration and automatic swell (DM = LOW) RINGING BURST NUMBER (N) 1 2 >2 LOW HIGH HIGH Notes 1. Typical pulse durations, tfund and tharm, for the delta-modulated approximation of fundamental and harmonic signals; valid for fOSC = 64 kHz and fclk = 32 kHz. See Fig.6 and Fig.7. 2. SPL is the relative Sound Pressure Level, and 0 dBr is defined as the SPL for IS1 = IS2 = HIGH. 3. Values of the DC resistance Rxy, bell impedance (Zi) and SPL are valid for a value of input voltage Vi(rms) = 40 V.

When IS1 and IS2 are both LOW, the circuit operates in the automatic swell mode. The SPL then increases in three steps so that the maximum level is reached for the third ringing burst. Each time VDD drops below VAS the automatic swell register is reset and the next ringing burst is considered as N = 1 (see Table 4). A buffer capacitor (see Fig.8) must hold VDD > VAS during the time between two consecutive ringing bursts of a series. For each of the other three combinations of pins IS1 and IS2 the pulse duration has a constant value. Thus the ringer can be designed so that the impedance represented at the telephone line will comply with postal requirements that vary in relation to parallel or series connections of more than one ringer. To satisfy some applications, a harmonic signal is added to the fundamental frequency in the last step of the automatic swell mode. The pulses representing this harmonic signal are interleaved with the pulses of the fundamental signal (see Fig.7). The difference in pulse duration shown in Table 4, is chosen so that the harmonic level is 10 dB below the fundamental level. The harmonic frequency range is from 2 kHz to 3.2 kHz. The individual harmonic frequencies for the seven tone codes and the relative fundamental frequencies are shown in Table 5. Table 5

Using a single mask it is possible to program the following: * Addition of harmonics in all the other input states of IS1 and IS2 * All pulse duration values * Other even harmonic frequencies. 7.10 Optical output (OPT)
The OPT output is designed to drive an optical signal transducer or lamp. It is LOW when the ringer circuit is enabled and HIGH when the ringer circuit is disabled. This output can also be used to switch the transmitter ON and OFF in the base unit of a cordless telephone set.

Lead lengths of ROSC and COSC to be kept to a minimum. 12 APPLICATION INFORMATION Application of the PCD3360 in a telephone ringer circuit together with a loudspeaker is shown in Fig.8. The threshold levels VH and VL of the frequency discriminator circuit are determined by: * The logic threshold of input FDI (0.5VDD, typically 3.4 V for VDD = 6.8 V) * The pull-down current of input FDI (20 A typically for FDI < 3.4 V) * The value of R2 (680 k in Fig.8). For a positive slope the voltage at R2 must exceed the value VH before FDI will become HIGH; VH is the sum of the input threshold and the voltage drop across R2 thus: -3 -6 V H = 3.4 + 680 x 10 x 20 x 10 = 17 V For a negative slope, the voltage at R2 must decrease below the value of VL before FDI will become LOW. Because the current into FDI is negligible with FDI = HIGH the voltage drop across R2 can be discounted, thus VL = 3.4 V. The minimum operating voltage across C3 is 17.8 V which is determined by: * The minimum operating voltage of the PCD3360 (5.8 V) * The supply current of the PCD3360 (120 A max.) * The value of R3 (100 k in Fig.8). The total switch-on delay equals approximately the time required to charge the supply capacitor C3 to the minimum operating value, plus the specified switch-on delay of the PCD3360. The high operating voltage combined with the class D output stage ensures the optimal energy conversion and thereby a high sound level. The design can easily be optimized for parallel or series connection of more than one ringer. The diode bridge, zener diode (D1) and resistor R1 protect the ringer against transients up to 5 kV. During these surges the voltage on the 68 V zener diode (BZW03-C68) can rise to 100 V; the DMOS transistor BST72A (TR1) has a maximum drain-source voltage of 100 V. Up to 220 V, 50 Hz can be applied to the a/b terminals without damaging the ringer. The choke (L1) in series with the 50 loudspeaker increases the sound pressure level by approximately 3 dB by suppression of the 32 kHz carrier frequency and its sidebands. The flyback diode BAX18A (D2) is a fast type with low forward voltage to obtain high efficiency. Application of the PCD3360 together with a PXE transducer is shown in Fig.9. The only significant difference between Fig.8 and Fig.9 is the output stage. Two BST72A transistors provide an output voltage swing almost equal to the voltage at C3. Pins IS1 and IS2 are inoperative because DM = HIGH. Volume control is possible using resistor RV.

14 SOLDERING 14.1 Introduction
PCD3360
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. This text gives a very brief insight to a complex technology. A more in-depth account of soldering ICs can be found in our "IC Package Databook" (order code 9398 652 90011). 14.2 14.2.1 DIP SOLDERING BY DIPPING OR BY WAVE
Several techniques exist for reflowing; for example, thermal conduction by heated belt. Dwell times vary between 50 and 300 seconds depending on heating method. Typical reflow temperatures range from 215 to 250 C. Preheating is necessary to dry the paste and evaporate the binding agent. Preheating duration: 45 minutes at 45 C. 14.3.2 WAVE SOLDERING
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. * The longitudinal axis of the package footprint must be parallel to the solder flow. * 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. 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. A mildly-activated flux will eliminate the need for removal of corrosive residues in most applications. 14.3.3 REPAIRING SOLDERED JOINTS
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 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. 14.2.2 REPAIRING SOLDERED JOINTS
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. 14.3 14.3.1 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.
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.
