Product Summary
The TDA5211T is a very low power consumption single conversion receiver for the frequency band 310 to 350 MHz. The device offers a high level of integration and needs only a few external components. The TDA5211T 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. Applications include: Keyless Entry Systems, Remote Control Systems, Alarm Systems, Low Bitrate Communication Systems.
