Overview
Data Sheet High Frequency Divider/PLL Synthesizer ADF4007 FEATURES 7.
5 GHz bandwidth Maximum PFD frequency of 120 MHz Divide ratios of 8, 16, 32, or 64 2.
7 V to 3.
3 V power supply Separate charge pump supply (VP) allows extended tuning voltage in 3 V systems RSET control of charge pump current Hardware power-down mode APPLICATIONS Satellite communications Broadband wireless access CATV Instrumentation Wireless LANs GENERAL DESCRIPTION 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 reference divider is permanently set to 2, allowing an external REFIN frequency of up to 240 MHz.
A complete PLL (phase-locked loop) can be ...
