5 / 44 page Product Info Product Info Wireless Components confidential Target Specification, October 2001 Package TDA 5220 preliminary 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. 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 inte- grated 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 bat- tery life. Features s Low supply current (typ. at 868MHz Is = 5.9mA in FSK mode, Is = 5.2mA in ASK mode) s Supply voltage range 5V ±10% s Power down mode with very low supply current (50nA typ) s FSK and ASK demodulation capa- bility s Fully integrated VCO and PLL Synthesiser s ASK sensitivity < –107dBm s Selectable frequency ranges 810- 870 MHz and 400-440 MHz s Limiter with RSSI generation, operating at 10.7MHz s Selectable reference frequency s 2nd order low pass data filter with external capacitors s Data slicer with self-adjusting threshold s FSK sensitivity <-100dBm Application s Keyless Entry Systems s Remote Control Systems s Alarm Systems s Low Bitrate Communication Systems Ordering Information Type Ordering Code Package TDA 5220 P-TSSOP-28-1 samples available on tape and reel |
