The 2 GHz max frequency covers UHF, ISM bands, and cellular basestation LO chains — the synthesizer's phase-noise floor and charge-pump linearity determine the close-in phase noise of the VCO it locks. Input accepts CMOS or TTL reference signals; output is a single-ended clock. The 3:1 input-to-output ratio allows multiplexing three reference sources into one PLL path — handy for redundant reference switching in a radio card. ## Supply range and temperature grade The wide range also helps when the PLL shares a supply with a noisy digital rail; a little headroom lets an RC filter clean the feed before it hits the charge pump. The 20-TSSOP package (0.65 mm pitch) is hand-reworkable with a hot-air station — just preheat the board to 100°C to avoid pad lifting on the fine-pitch legs. ## Active lifecycle and compliance ROHS3 compliant. ## Differential input, single-ended output The reference input accepts differential signals (Yes/No for Input:Output) — useful when the reference is a differential OCXO or a balun-coupled sine source. The output is single-ended, so the PLL drives a standard CMOS clock buffer or a VCO tuning port directly.","metaTitle":"ADF4208BRUZ PLL Clock Synthesizer – 2 GHz, 20-TSSOP, Active","metaDescription":"Analog Devices ADF4208BRUZ PLL frequency synthesizer, 2 GHz max, 2.7-5.5V supply, industrial temp -40°C to 85°C, 20-TSSOP.

Its max frequency is 2.7 GHz — 700 MHz higher — so it covers higher bands (e.g., 2.4 GHz ISM, 2.6 GHz LTE) that the ADF4208BRUZ at 2 GHz does not. If your LO target is below 2 GHz, the ADF4208BRUZ is the cost-optimised choice; the ADF4212BRUZ adds headroom for future band expansion."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/ADF4208BRUZ","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/ADF4208BRUZ when reusing this data.
