Neubiberg, Germany
Wireless Control Transmitter TDK5110F
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
