3 / 52 page Product Info Product Info Wireless Components Data Sheet, December 2008 Package TDA7210 Product Info General Description The IC is a very low power consump- tion single chip FSK/ASK Superhet- erodyne Receiver (SHR) for the frequency bands 810 to 870 MHz and 400 to 440 MHz that is pin compatible with the Receiver TDA5210. The IC offers a high level of integration and needs only a few external compo- nents. The device contains a low noise amplifier (LNA), a double balanced mixer, a fully integrated VCO, a PLL synthesiser, a crystal oscillator, a lim- iter with RSSI generator, a PLL FSK demodulator, a data filter, a data com- parator (slicer) and a peak detector. Additionally there is a power down fea- ture to save battery life. Features ■ Low supply current (typ. at 868MHz Is = 5.9mA in FSK mode, Is = 5.2mA in ASK mode) ■ Supply voltage range 5V ±10% ■ Power down mode with very low supply current (50nA typ) ■ FSK and ASK demodulation capa- bility ■ Fully integrated VCO and PLL Synthesiser ■ ASK sensitivity < –107dBm ■ Selectable frequency ranges 810- 870 MHz and 400-440 MHz ■ Limiter with RSSI generation, operating at 10.7MHz ■ Selectable reference frequency ■ 2nd order low pass data filter with external capacitors ■ Data slicer with self-adjusting threshold ■ FSK sensitivity <-100dBm Application ■ Keyless Entry Systems ■ Remote Control Systems ■ Alarm Systems ■ Low Bitrate Communication Systems Ordering Information Type Ordering Code Package TDA7210 SP000524274 PG-TSSOP-28 samples available on tape and reel |
