What this 7.5 GHz PLL synthesizer does for your RF chain
The ADF4007BCPZ is a PLL-based clock/frequency synthesizer from Analog Devices, designed for RF applications that need a clean local oscillator or clock up to 7.5 GHz. It accepts CMOS or TTL reference inputs and delivers a single-ended clock output with a 2:1 input-to-output ratio.
Frequency ceiling and supply rail margin
The 7.5 GHz maximum frequency is the highest among the sibling PLLs in this series — the ADF4106BCPZ tops out at 6 GHz, the ADF4113HVBCPZ at 4 GHz, and the ADF4112BCPZ at 3 GHz. If your design needs to lock a VCO above 6 GHz, the ADF4007BCPZ is the only one in this footprint that gets there. The supply range of 2.7V to 3.3V is shared across the family, so no rail change is needed when swapping between them.
Active production and compliance status
It is ROHS3 compliant, so it meets current EU restriction requirements without an exemption. The part ships in a tray and uses a 20-lead LFCSP with exposed pad — the 4x4 mm footprint is common for RF PLLs in this class.
