It is intended primarily for FSK data systems. The design is very similar to MC3356 except that the oscillator/mixer has been removed, and the frequency capability of the IF has been raised about 2:1. The detector output configuration has been changed to a balanced, open–collector type to permit symmetrical drive of the data shaper (comparator). Meter drive and squelch features have been retained. The limiting IF is a high frequency type, capable of being operated up to 100 MHz. It is expected to be used at 40 MHz in most cases. The quadrature detector is internally coupled to the IF, and a 2.0 pF quadrature capacitor is internally provided. The 20 dB quieting sensitivity is approximately 20 µV, tuned input, and the IF can accept signals up to 220 mVrms without distortion or change of detector quiescent DC level. The IF is unusual in that each of the last 5 stages of the 6 stage limiter contains a signal strength sensitive, current sinking device. These are parallel connected and buffered MOTOROLA ANALOG IC DEVICE DATA to produce a signal strength meter drive which is fairly linear for IF input signals of 20 µV to 20 mVrms (see Figure 4). A simple squelch arrangement is provided whereby the meter current flowing through the meter load resistance flips a comparator at about 0.8 Vdc above ground. The signal strength at which this occurs can be adjusted by changing the meter load resistor. The comparator (+) input and output are available to permit control of hysteresis. Good positive action can be obtained for IF input signals of above 20 µVrms. A resistor (R) from Pin 13 to Pin 12 will provide VCC/R of feedback current. This current can be correlated to an amount of signal strength hysteresis by using Figure 4. The squelch is internally connected to the data shaper. Squelch causes the data shaper to produce a high (VCC) output. The data shaper is a complete “ floating” comparator, with diodes across its inputs. The outputs of the quadrature detector can be fed directly to either or preferably both inputs of the comparator to produce a squared output swinging from VCC to ground in inverted or noninverted form. 7 MC13055 OUTLINE DIMENSIONS P SUFFIX PLASTIC PACKAGE CASE 648–08 ISSUE R –A– 16 9 1 8 NOTES: 1.
