Analog Devices ADF7901 Datasheet
The ADF7901 is a single‑chip, low‑power UHF transmitter designed for RF remote‑control devices. It operates from 369.5 MHz to 395.9 MHz using a fractional‑N PLL and integrated VCO, supports OOK and FSK modulation at data rates up to 50 kbps, and offers eight channel selections via three external control lines. Power‑down mode draws less than 1 µA.
The datasheet provides detailed specifications, pin functions, typical performance graphs, layout guidelines, and ordering information for the 24‑lead TSSOP package. It also includes recommended loop‑filter components and ESD handling precautions.
