3 GHz PLL synthesizer for RF local-oscillator chains
The ADF4210BCP is a PLL frequency synthesizer generating clock outputs up to 3 GHz from a CMOS or TTL reference input. It operates from a 2.7 V to 5.5 V supply and includes an integrated divider/multiplier (ratio 3:1 input-to-output).
The 2.7 V to 5.5 V supply range lets this part drop into either a 3.3 V or 5 V rail without a dedicated LDO, saving a regulator on the BOM.
Package and mounting — 20-LFCSP with exposed pad
RoHS non-compliance — regulatory check required
The ADF4210BCP is marked RoHS non-compliant. This means it contains lead or other restricted substances above the exemption thresholds. For EU, UK, or other RoHS-enforced markets, you will need a specific exemption (e.g., for high-reliability telecom infrastructure) or plan for a compliant alternate.
Sourcing posture — active, but non-RoHS limits channel
Because the part is active and non-RoHS, the franchised channel carries it but many distributors restrict non-compliant stock to specific regions or require a customer RoHS waiver. Independent distribution holds inventory for legacy BOMs that do not require RoHS compliance.
