Overview
The IC is a very low power consumption single chip FSK/ASK Superheterodyne Receiver (SHR) for the frequency band 300 to 340 MHz. The IC offers a high level of integration and needs only a few external components. 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.
Features
⢠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
⢠Limiter with RSSI generation, operating at 10.7MHz
⢠2nd order low pass data filter with external capacitors ⢠Data slicer with selection between two threshold modes ⢠FSK sensitivity better than -102 dBm over specified temperature range (- 40 to +105°C)
Application
⢠Keyless Entry Systems
⢠Remote Control Systems
⢠Alarm Systems
⢠Low Bitrate Communication Systems
