TDK5110F - Transmitter with integrated FSK - switch
The TDK5110F is a single chip ASK/FSK transmitter for the frequency bands 433 – 435 MHz and 868 – 870 MHz. The IC offers a high level of integration and needs only a few external components. The device contains a fully integrated PLL synthesizer and a high efficiency power amplifier to drive a loop antenna. A special circuit design and a unique power amplifier design are used to save current consumption and therefore to save battery life. Additional features like power down mode and divided clock output are implemented. The IC can be used for both ASK and FSK modulation.
Summary of Features
Frequency range 433 – 435 MHz/868 – 870MHz
ASK and FSK modulation
High efficiency power amplifier typically 10dBm @ 3 V
Fully integrated frequency synthesizer
VCO without external components
Fully integrated frequency synthesizer
Power down mode
Divided clock output for μC
Low external component count
Integrated FSK-switch
Low supply current typ. 14mA @ 3 V
Voltage supply range 2.1 – 4V
Temperature range -40 … +125°C
Potential Applications
Remote Keyless Entry (RKE) systems
Tire Pressure Monitoring (TPM) systems
Remote control systems
Alarm systems
Communication systems
