Control receiver, TDA7210, INFINEON

The IC is a very low power consumption single chip FSK/ASK Superheterodyne Receiver (SHR). 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, a data comparator (slicer) and a peak detector. Additionally there is a power down feature to save battery life.

Features

• FSK and ASK demodulation capability
• Fully integrated VCO and PLL synthesiser
• ASK sensitivity < – 107 dBm
• 2nd order low pass data filter with external capacitors
• FSK sensitivity <- 100 dBm

Applications

• Keyless entry systems
• Remote control systems
• Alarm systems
• Low bitrate communication systems
