The TDK 5100 F is a single chip ASK/FSK transmitter for operation in the frequency band 433-435 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 an unique power amplifier design are used to save current consumption and therefore to save battery life. Additional features are a power down mode and a divided clock output. | Summary of Features: Fully integrated frequency synthesizer; VCO without external components; ASK and FSK modulation; Frequency range 433-435 MHz; High efficiency power amplifier (typically 5 dBm); Low supply current; Voltage supply range 2.1 ... 4 V; Temperature range 40 ... 125C; Power down mode; Crystal oscillator 13.56 MHz; FSK-switch; Divided clock output for C; Low external component count | Target Applications: Tire pressure monitoring systems; Keyless entry systems; Remote control systems; Alarm systems; Communication systems
