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 high‑frequency divider/PLL synthesizer is designed for communications, satellite, broadband wireless, CATV, instrumentation, and wireless LAN applications. It combines a low‑noise digital phase‑frequency detector, a precision charge pump, and a programmable divider/prescaler, allowing operation up to 7.5 GHz on the RF side and a 120 MHz phase‑frequency detector.
Key features include a 2.7 V‑3.3 V power supply range, separate charge‑pump supply, selectable divide ratios (8, 16, 32, 64), and a variety of pin functions for flexible integration. The datasheet provides detailed specifications, absolute maximum ratings, pin descriptions, typical performance curves, and design guidelines for PCB layout and chip‑scale packaging.
