The ADF4007 is a high frequency divider/PLL synthesizer that can be used in a variety of communications applications. It can operate to 7.5 GHz on the RF side and to 120 MHz at the PFD. It consists of a low noise digital PFD (phase frequency detector), a precision charge pump, and a divider/prescaler. The divider/prescaler value can be set by two external control pins to one of four values (8, 16, 32, or 64).
The ADF4007 is a high‑frequency divider/PLL synthesizer that operates up to 7.5 GHz on the RF side and supports a phase‑frequency detector (PFD) frequency of up to 120 MHz. It offers selectable divide ratios of 8, 16, 32 or 64, a 2.7 V‑3.3 V power‑supply range, and a dedicated charge‑pump supply for extended tuning voltage.
The datasheet includes detailed specifications, absolute maximum ratings, pin‑function tables, typical performance curves, theory of operation, PCB design guidelines for the chip‑scale package, outline dimensions, and ordering information. These sections help designers integrate the ADF4007 into satellite communications, broadband wireless, CATV, instrumentation, and wireless LAN applications.
