This document describes the features and characteristics of the TDK5100F 434 MHz ASK/FSK transmitter.
The TDK5100F is a single‑chip ASK/FSK transmitter designed for the 433‑435 MHz band. It integrates a PLL synthesizer, a high‑efficiency power amplifier and a divided clock output, requiring only a few external components.
Key features include a supply voltage range of 2.1 V‑4 V, operation from –40 °C to +125 °C, a typical output power of 5 dBm, a crystal oscillator at 13.56 MHz and a clock output (CLKOUT) at 847.5 kHz. Pin definitions and functional block diagrams are provided for easy integration.
