ASK/FSK 915MHz Wireless Transceiver
TDA5252 G2
Product Info
General Description
The IC 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, 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.
Features
– Low supply current (I
– Supply voltage range 2.1 - 5.5V
– Power down mode with very low supply
– FSK and ASK modulation and demodulation
– Fully integrated VCO and PLL
Application
– Low Bitrate Communication
– Keyless Entry Systems
– Remote Control Systems
– Alarm Systems
– Telemetry Systems
