TDA5252 Wireless Communication Module Low Power ASK/FSK 915MHz Wireless Transceiver

TDA5252 Wireless Communication Module Low Power ASK/FSK 915MHz Wireless Transceiver

Product Description Of TDA5252
TDA5252 is a low power consumption single chip FSK/ASK Transceiver for half duplex low datarate communication in the 915MHz band. The IC offers a very high level of integration and needs only a few external components. It contains a highly efficient power amplifier, a low noise amplifier (LNA) with AGC, a double balanced mixer, a complex direct conversion stage, |/Q limiters with RSSI generation, an FSK demodulator, a fully integrated VCO and PLL synthesizer, a tuneable crystal oscillator, an onboard data filter, a data comparator (slicer), positive and negative peak detectors, a data rate detection circuit and a 2/3-wire bus interface. Additionally there is a power down feature to save battery power.
