Transceptor Uhf 433mhz Fsk Ask Tda5255 Tssop38 Itytarg

Wireless Control – The TDA525x series is a family of low power single chip
FSK/ASK transceivers for half duplex low data rate communication in the
315 MHz, 434 MHz, 868 MHz and 915 MHz bands.
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,
I/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.

Applications
Low bitrate communication systems
Remote Keyless Entry (RKE) systems
Remote control systems
Alarm systems
Telemetry systems
Home automation systems
