www.analog.com 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 REF
IN
frequency of
up to 240 MHz.
A complete PLL (phase-locked loop) can be implemented if the
synthesizer is used with an external loop filter and a VCO
(voltage controlled oscillator). Its very high bandwidth means
that frequency doublers can be eliminated in many high
frequency systems, simplifying system architecture and
reducing cost.
