The design is based on the SL6609A but is specifically designed for use in very small pagers i.e. credit card sized, where local oscillator re-radiation is a problem. This design has overcome this difficulty. TPX 1 28 IAGCOUT MIXER DECOUPLE 2 27 IRFAMP MIXA The device also includes a 1 volt regulator capable of sourcing up to 5mA, a battery flag and the facility of incorporating a more complex post detection filter off-chip. Both battery flag and data outputs have open collector outputs to ease their interface with other devices. Adjacent channel rejection is provided using tuneable gyrator filters. To assist operation in the presence of large interfering signals both RF and audio AGC functions are provided.

It is available in a 28 pin SSOP package and it integrates all the facilities required for the conversion of an RF FSK signal to a base-band data signal. Low Noise Amplifier To achieve optimum performance it is necessary to incorporate a Low Noise RF Amplifier at the front end of the receiver. This is easily biased using the on chip voltage and current sources provided. Gyrator Filters The on chip filters include an adjustable gyrator filter. This may be adjusted with the use of an additional resistor between pin 4 and GND. This allows flexibility of filter characterstics and also allows for compensation for possible process variations. Audio AGC All voltages and current sources used for bias of the RF amplifier, receiver and mixers should be RF decoupled using suitable capacitors (see fig.4 for a suitable Low-NoiseAmplifier). The Audio AGC fundamentally consists of a current sink which is controlled by the audio (baseband data) 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 (see Fig.6 and 7). See Application note for details. Local Oscillator Regulator 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 the -3dB/45° transfer characteristic, giving a full 90° phase differential between the LO ports of the device. Each LO port of the device also requires an equal level of drive from the Oscillator. (see Fig.5). The on chip regulator must 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 VCE > = 0.1V Pin Number Pin Name Pin Description 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 TPX MIX-DEC LOY GYRI LOX VR TPY GTHADJ TCADJ BEC BATTFL TPLIMY VCC2 DATAOP TPLIMX BRF2 BRF1 DIG GND VBG VBATT VCC1 REGCNT VREG MIXB GND MIXA IRFAMP 28 IAGCOUT X channel pre-gyrator filter test-point.
