TDA5200

概要

The IC is a very low power consumption single chip ASK Single Conversion Receiver for receive frequencies bands 868-870 MHz and 433-435 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 synthesizer, a crystal oscillator, a limiter with RSSI generator, a data filter, a data comparator (slicer) and a peak detector. Additionally there is a power down feature to save battery life.

特長

  • Low supply current (I s = 4.8 mA typ. at 868 MHz, I s = 4.6 mA typ. at 434 MHz)
  • Supply voltage range 5 V ±10 %
  • Power down mode with very low supply current (50 nA typ)
  • Fully integrated VCO and PLL Synthesizer
  • RF input sensitivity < – 107 dBm
  • Selectable frequency ranges around 868-870 MHz and 433-435 MHz
  • Selectable reference frequency
  • Limiter with RSSI generation, operating at 10.7 MHz
  • 2 nd order low pass data filter with external capacitors
  • Data slicer with self-adjusting threshold
