Product Brief TDA522x Series ASK/FSK Receiver Family W i r e l e s s C o n t r o l – T h e T D A 5 2 2 x s e r i e s is a family of very low power single chip ASK/FSK receivers the frequency bands 300 – 340 MHz, 400 – 440 MHz and 810 – 870 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 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. ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ Applications ■ Features ■ Remote Keyless Entry (RKE) systems Tire Pressure Monitoring (TPM) systems Remote control systems Alarm systems Low bit rate communication Systems ■ ■ ■ ■ Ordering Information ■ ■ Type Ordering Code Package TDA5220 Q67100-H2049 P-TSSOP-28 TDA5221 Q67100-H2051 P-TSSOP-28 ■ Frequency ranges 300 – 340 MHz, 400 – 440 MHz and 810 – 870 MHz FSK and ASK demodulation Fully integrated VCO and PLL Synthesiser ASK sensitivity < -107 dBm FSK sensitivity < -100 dBm Limiter with RSSI generation, operating at 10.7 MHz Selectable reference frequency 2 nd order low pass data filter with external capacitors Data slicer with self-adjusting threshold Switchable Peak Detector Switchable Comparator Power down mode with very low supply current (50 nA typ.)
