TDA525x Series

ASK/FSK Transceiver Family

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.
