Transceiver TDA5251 F1 ASK/FSK 315MHz Wireless Transceiver

Transceiver TDA5251 The IC TDA5251 is a low power consumption single chip FSK/ASK Transceiver for the frequency band 315MHz. The IC combines a very high level of integration and minimum external part count. The device contains a Low Noise Amplifier (LNA), a double balanced mixer, a fully integrated VCO a PLL synthesizer, a crystal Oscillator with FSK Modulator a limiter with RSSI generator, an FSK Demodulator a data Filter a data Comparator (slicer), a positive and a negative data peak detector, 2 a highly efficient power Amplifier and a complex digital Timing and control unit with I C/3-wire Microcontroller Interface Additionally there is a power down feature to save battery power. The transmit section uses direct ASK modulation by switching the power Amplifier and crystal Oscillator detuning for FSK modulation. The necessary detuning load capacitors are external. The capacitors for fine tuning are integrated. The receive section is using a novel single-conversion/ direct-conversion scheme that is combining the advantages of both receive topologies. The IF is contained on the chip, no RF channel Filters are necessary as the channel Filter is also on the chip. The self-polling Logic CAN be used to let the device operate autonomously as a master for a decoding Microcontroller By Infineon Technologies Corporation
