This is easily biased using the on-chip voltages and current source provided. All voltages and current sources used for bias of the RF amplifier, receiver and mixers should be RF decoupled using 1nF capacitors. The receiver also requires a stable Local Oscillator at the required channel frequency. SL6619 the external AGC circuit by causing a PIN diode to conduct, reducing the signal to the RF amplifier. RF AGC The RF AGC is an automatic gain control loop that protects the mixer’s RF inputs, Pins 3 and 5, from large out of band RF signals. The loop consists of an RF received signal strength indicator which detect the signal at the inputs of the mixers. This RSSI signal is then used to control the LNA current source (pin 1). Local Oscillator The Local Oscillator signal is applied to the device in phase quadrature. This can be achieved with the use of two RC networks operating at their 23dB/45° transfer characteristic. The RC characteristics for I and Q channels are combined to give a full 90° phase differential between the LO ports of the device. Each LO port also requires an equal level of drive from the oscillator. This is achieved by forming the two RC networks into a power divider. Regulator The on-chip regulator should be used in conjunction with a suitable PNP transistor to achieve regulation. As the transistor forms part of the regulator feedback loop the transistor should exhibit the following characteristics: HFE.100 for V CE. = 0·1V If no external transistor is used, the maximum current sourcing capability of the regulator is limited to 30µA. Gyrator Filters The on-chip filters include an adjustable gyrator filter. This may be adjusted by changing the value of the resistor connected between pin 13 and GND. This allows adjustment of the filters’ cutoff frequency and allows for compensation for possible process variations. Automatic Frequency Control (Fig. 4) The Automatic Frequency Control consists of a detection circuit which gives a current output at AFC OP whose magnitude and sign is a function of the difference between the local oscillator (fLO) and carrier frequencies (fC). This output current is then filtered by an off-chip integrating capacitor. The integrator’s output voltage is used to control a voltage control crystal oscillator. This closes the AFC feedback loop giving the automatic frequency control function. For an FSK modulated incoming RF carrier, the AFC OP current’s polarity is positive, i.e.current is sourced for fLO,fC ,fLO14kHz and negative, i.e. current is sunk, for fLO.fC .fLO24kHz. The magnitude of the AFC OP current is a function of frequency offset and the transmitted data’s bit stream. If the carrier frequency, (f C), equals the local oscillator frequency, (fLO) then the magnitude of the current is zero. Audio AGC (Fig. 3) The Audio AGC consists of a current sink which is controlled by the audio (baseband) signal. It has three parameters that may be controlled by the user. These are the attack (turn on ) time, decay (duration) time and threshold level. The attack time is simply determined by the value of the external capacitor connected to TCADJ. The external capacitor is in series with an internal 100kΩ resistor and the time constant of this circuit dictates the attack time of the AGC. i.e. tATTACK = 100kΩ3C18 The decay time is determined by the external resistor connected in parallel with the capacitor CTC. The decay time is simply t DECAY = R173 C18 When a large audio (baseband) signal is incident on the input to the AGC circuit, the variable current source is turned on. This causes a voltage drop across R13. The voltage potential between VREF and the voltage on pin 31 causes a current to flow in pin 30. This charges up C18 through the 100k Ω internal resistor. As the voltage across the capacitor increases, a current source is turned on and this sinks current from pin 32. The current sink on pin 32 can be used to drive BIT RATE FILTER CONTROL The logic level on pin 26 controls the cutoff frequency of the 1st order bit rate for a given bit rate filter capacitor at pin 27. This allows the cutoff frequency to be changed between fC, 2f C and 0·43f C through the logic level on pin 26. This function is achieved by changing the value of the current in the 4f detector’s output stage. A logic zero (0V to 0·1V) on pin 26 gives a cutoff frequency of fC a logic one (VCC22 0·3V to VCC2) gives a cut off frequency of 2fC and an open circuit at pin 26 gives a cutoff frequency of 0·43fC. 9 SL6619 Data Sheet SL6619 VCC VREF15mV RF INPUT VCC1 CURRENT SOURCE 1 − + 32 − 100k 30 TO RF AMP + 31 R13 C34 R17 RDECAY C18 CTC VREF VREF Figure 3 - AGC schematic SL6619 VOLTAGE REFERENCE VCC2 18 CVREF C15 CINT 1 C30 CINT 2 TO VCXO VARACTOR DIODE AFC DETECTION CIRCUIT 0µA/5µA 19 5µA/0µA R11 C21 R15 VCC1 24 25 320k C22 Figure 4 - AFC schematic Peak deviation (kHz) 3·5 4 4·5 5 5·5 Baud rate (bps) 512, 1200, 2400 512, 1200, 2400 512, 1200, 2400 512, 1200, 2400 512, 1200, 2400 Component (Fig. 4) C22 750pF 560pF 510pF 470pF 430pF C21 2·0nF 1·5nF 1·3nF 1·2nF 1·1nF R11 15kΩ 15kΩ 15kΩ 15kΩ 15kΩ Table 2 - AFC defining components 10 VREF TP LIM I BRF CNT VCC1 VCC1 C34 R13 R17 C18 C23 C27 VCC1 C22 C21 C24 VCC1 R10 BRF1 BRF CNT AFC2 R11 GTH ADJ TC ADJ IAGC OP TP LIM I 29 24 23 22 21 VCC2 DATA OP BEC 20 19 18 17 AFC OP VREF TPQ 14 GYR I 15 Q1 16 Q2 C15 C16 C17 R15 C30 VCC1 32 IRF 1 2 3 4 BATT FLAG AFC1 R16 31 30 VBATT 28 27 26 25 VCC2 C6 C33 GND TO TR2 VCC2 C19 R9 R8 C20 VREF MIXIP A VC1 T1 C25 R2 R3 MIX DEC MIXIP B 5 6 7 8 9 I1 I2 VCC1 LOIP I 10 11 12 13 REG CNT DATA OP BEC AFC OP VREF SL6619 TR1 TR3 C26 C7 C8 VREG TPI RF IN VCC1 VREG L1 C3 TR2 FROM IRF (PIN 1) C1 C2 R1 C5 LOIP Q C4 C9 VREG C10 R14 VCC1 C12 R5 R7 VREG R12 C28 VCC1 R4 C29 C32 C11 C14 Figure 5 - SL6619 characterisation circuit (see Tables 3 and 4 for component values) R6 C13 Data Sheet SL6619 EXT LO 11 SL6619 Data Sheet Resistors Capacitors C1 C2 C3 C4 C5 C6 C7 C8 C9 C10 C11 C12 C13 C14 C15 C16 C17 12pF O/C 220nF 1nF 1nF 1nF 1nF 3·3pF 4·7nF 4·7nF 4·7pF 5·6pF 1nF 1nF 1nF 1nF 2·2µF Capacitors (cont.)
