3 / 11 page Radiometrix Ltd, SILRX-UHF Data Sheet page 3 Pin Description pin 1 RF IN The receiver antenna connects to this input. It has nominal RF impedance of 50Ω and is capacitively isolated from the internal circuit pin 2 RF GROUND This pin should be connected to any ground plane against which the antenna works. It is internally connected to pin 4. pin 3 DETECT This pin may be used to derive a carrier detect to enable external circuits when a signal is being received. If the detect function is not being used a 10 kΩ pull-up to pin 5 (Vcc) should be connected. Refer to applications note for further details on the use of this pin. pin 4 0 volt Ground for supply. pin 5 Vcc Positive supply of 4V to 9V 13 mA. The supply must be clean (<2mV pp) stable and free of high frequency digital noise. A supply filter is recommended unless the module is driven from it’s own regulated supply. pin 6 AF This is the FM demodulator output. It has an standing DC bias of approximately 1.4V and may be used to drive analogue data detectors such as modem chips or DTMF decoders. Load impedances as low as 2 kΩ and up to 100 pF can be driven pin 7 DATA This digital output from the internal data slicer is a squared version of the signal on pin 6 (AF) This signal is used to drive external digital decoders, it is true data (i.e. as fed to the transmitters data input). Load impedances as low as 1 kΩ and up to 1 nF can be driven . figure 3: Mechanical Dimensions: |
