Obsolescence Notice This product is obsolete. This information is available for your convenience only. For more information on Zarlink’s obsolete products and replacement product lists, please visit http://products.zarlink.com/obsolete_products/ JULY 1995 ADVANCE INFORMATION DS4015 - 2.5 SL6609A DIRECT CONVERSION FSK DATA RECEIVER This device is an advanced direct conversion receiver for operation up to 470MHz. The design is based on the SL6609 receiver and is a pin for pin product upgrade. The device integrates all functions to translate a binary FSK modulated RF signal into a demodulated data stream. 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. 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.

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. 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). 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 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). 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 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 Figs.6 and 7). See Application note for details. Regulator 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 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 28 Pin Name TPX RFIADJ 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 IAGCOUT Pin Description X channel pre-gyrator filter test-point.

L2 is used in the Audio AGC circuit (see Fig. 6). For the characteristics of the Audio AGC current source see Fig.7. If the audio AGC is not required then the current source (Pin 28) may be disabled by connecting Pin 9 (TCADJ) to VR (Pin 6) and by connecting Pin 28 (IAGCOUT) to Vcc1, (R18). The voltage at Pin 8 may still be used as an RSSI. R9, C8, C14, C19, R17 and D1 may then be omitted. See Fig.6 for AGC component values. 4.

The values given are for the RF amplifier specified in the Applications Circuit with no Audio AGC connected. i.e. R17 and D1 omitted. Suggested diode for use with the Audio AGC circuit (see Fig.6) (D1 is not included on the general demonstration circuit). The value of R11 is dependent on the data output load. R11 should allow sufficient current to drive the data output load.
