High Frequency Divider/PLL Synthesizer

ADF4007

FEATURES

GENERAL DESCRIPTION

7.5 GHz bandwidth

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_INfrequency of

up to 240 MHz.

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 (V_P) allows

extended tuning voltage in 3 V systems

APPLICATIONS

Satellite communications

Broadband wireless access

CATV

Instrumentation

Wireless LANs

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.
