TDK 5111 is a wireless component operating at 315MHz.
The TDK 5111 is a single‑chip ASK/FSK transmitter for the 314‑317 MHz band. It integrates a PLL synthesizer and a high‑efficiency power amplifier, requiring only a few external components. The device includes a power‑down mode, low‑power detect and a programmable divided clock output.
The datasheet provides detailed pin definitions, functional block diagrams, electrical parameters such as supply voltage, current consumption, output power and timing diagrams for ASK and FSK modulation.
