6 / 49 page TDA7200 Product Description Data Sheet 6 V 1.0, 2007-05-02 1 Product Description 1.1 Overview The IC is a very low power consumption single chip FSK/ASK Superheterodyne Receiver (SHR) for the frequency band 400 to 440 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. 1.2 Features • Low supply current (Is = 5.7 mA typ. in FSK mode, Is = 5.0 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 -106 dBm over specified temperature range (-20 to +70°C) • FSK sensitivity better than -100 dBm over specified temperature range (-20 to +70°C) • 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 (see Section 2.4.8) 1.3 Application • Remote Control Systems • Alarm Systems • Low Bitrate Communication Systems Table 1 Order Information Type Ordering Code Package TDA7200 SP000296473 PG-TSSOP-28 |
