2.17 GHz integer-N synthesizer with integrated VCO
The Analog Devices ADF4360-2BCPZRL7 is an integer-N synthesizer (RF) with an integrated voltage-controlled oscillator, delivering clock outputs up to 2.17 GHz. It accepts CMOS or TTL reference inputs and provides a single-ended clock output through a 1:2 fanout buffer. The part operates from a 3V to 3.6V supply and includes an on-chip divider (yes) but no multiplier. Housed in a 24-LFCSP (4x4 mm) package with an exposed pad for thermal management, it is rated for the industrial temperature range of -40°C to 85°C. Typical applications include wireless infrastructure basestations, microwave point-to-point radios, test equipment, and any RF local-oscillator chain needing a compact, integer-N PLL with a built-in VCO.
Package and mounting
The 3V to 3.6V supply range covers standard 3.3V rails with margin. At 3.3V nominal, the PLL and VCO blocks are fully specified; the part will hold lock across the full -40°C to 85°C range, which covers outdoor telecom cabinets and unconditioned industrial enclosures. The 24-LFCSP exposed pad must be soldered to a ground plane — without a thermal via stitch under the pad, the VCO phase noise degrades above 70°C case temperature. The 1:2 fanout means one reference input drives two clock outputs internally; both outputs are single-ended, not differential, so routing to a differential receiver needs an external balun or AC-coupling with a bias tee.
Active production — no LTB risk
The ADF4360-2BCPZRL7 carries an active lifecycle status with ROHS3 compliance. For new designs, this part is a safe selection; for production replenishment, the supply channel is stable through authorized distribution and independent stock.
Tray vs reel — the ADF4360-2BCPZ difference
The closest functional equivalent is the ADF4360-2BCPZ, which shares the same die, PLL architecture, 2.17 GHz max frequency, 24-LFCSP package, and temperature grade. The only difference is packaging medium: the -2BCPZRL7 ships in tape and reel (suitable for volume assembly), while the -2BCPZ ships in tray (prototyping and low-volume hand assembly). Both are electrically identical and pin-compatible. For a production BOM, the RL7 variant is the correct line item; for a lab bench build, the tray part is easier to handle without a feeder.
