The ADF4212L is a low power dual frequency synthesizer that can be used to implement local oscillators (LO) in the up-conversion and down-conversion sections of wireless receivers and transmitters. It can provide the L1 and L2 two frequency outputs. The L1 frequency range is from 800MHz to 2.4GHz and the L2 frequency range is from 200MHz to 1GHz.
The ADF4212L is a dual low‑power PLL frequency synthesizer designed for use as a local oscillator in wireless receivers and transmitters. It features a 3‑wire serial interface, programmable charge pump currents, fast‑lock mode, and operates from a 2.7 V to 3.3 V supply.
The document includes detailed specifications, pin‑out tables, timing diagrams, absolute maximum ratings, typical performance curves, and ordering information. It also offers application guidance for GSM, CDMA, WCDMA, cable‑TV tuners, and test equipment.
