Product Brief TDA 7200 The IC is a single chip FSK/ASK Superheterodyne Receiver (SHR) for the 400 to 440MHz frequency band with very low power consumption. It offers a high level of integration and only a few external components are needed to build a fully functional superheterodyne receiver. The device contains a low noise amplifier (LNA), a double balanced mixer, a fully integrated VCO, a PLL synthesizer, a crystal oscillator for the reference frequency, a limiter with RSSI generator, a PLL-based FSK demodulator, a data filter, a peak detector and an advanced data comparator (slicer) with the option of selection between two threshold modes. Additionally a power down feature is available which can save current and extends the battery life.
