DESCRIPTION
ProductDESCRIPTION
1.1 Overview The device contains a low noise amplifier (LNA), a double balanced mixer, a fully integrated VCO, a PLL synthesiser, a crystal oscillator, a limiter with RSSI generator, a PLL FSK demodulator, a data filter, an advanced data comparator (slicer) with selection between two threshold modes and a peak detector. Additionally there is a power down feature to save current and extend battery life, and two selectable alternatives of generating the data slicer threshold. 1.2FEATURES
● Low supply current (Is = 6.4 mA typ. in FSK mode, Is = 5.6 mA typ. in ASK mode)● Supply voltage range 5V ±10%
● Power down mode with very low supply current (50nA typ.)
● FSK and ASK demodulation capability
● Fully integrated VCO and PLL Synthesiser
● ASK sensitivity better than -110 dBm over specified temperature range (- 40 to +105°C)
● Selectable frequency ranges 300-320 MHz and 320-340 MHz
● Switchable between two different frequency channels (see Section 2.4.3)
