7 / 49 page  Product Description 2 - 2 TDA 5212 Wireless Components Specification, December 2006 2.1 Overview The IC is a very low power consumption single chip FSK/ASK Superheterodyne Receiver (SHR) for receive frequencies between 902 and 928 MHz that is pin compatible to the ASK Receiver TDA5202. The IC offers a high level of integra- tion 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. Addi- tionally there is a power down feature to save battery life. 2.2 Application ■ Keyless Entry Systems ■ Remote Control Systems ■ Low Bitrate ISM-band Communication Systems 2.3 Features ■ Low supply current (Is = 5.4 mA typ.FSK mode, 4.8 mA typ. ASK mode) ■ Supply voltage range 5V ±10% ■ Power down mode with very low supply current (90nA typ.) ■ FSK and ASK demodulation capability ■ Fully integrated VCO and PLL Synthesiser ■ RF input sensitivity ASK -112dBm typ. at 25°C, better than -109dBm over complete specified operating temperature range (-40 to +85°C) ■ RF input sensitivity FSK -105dBm typ. at 25°C, better than -102dBm over complete specified operating temperature range (-40 to +85°C) ■ Receive frequency range between 902 and 928 MHz ■ Selectable reference frequency ■ Limiter with RSSI generation, operating at 10.7MHz ■ 2nd order low pass data filter with external capacitors ■ Data slicer with self-adjusting threshold |
