PLL Frequency Synthesizer

ADF4107

FEATURES

GENERAL DESCRIPTION

7.0 GHz bandwidth

2.7 V to 3.3 V power supply

Separate charge pump supply (V_P) allows extended tuning

voltage in 3 V systems

Programmable dual-modulus prescaler

8/9, 16/17, 32/33, 64/65

Programmable charge pump currents

Programmable antibacklash pulsewidth

3-wire serial interface

Analog and digital lock detect

Hardware and software power-down mode

The ADF4107 frequency synthesizer can be used to implement

local oscillators in the up-conversion and down-conversion

sections of wireless receivers and transmitters. It consists of a

low-noise digital PFD (phase frequency detector), a precision

charge pump, a programmable reference divider, programmable

A and B counters, and a dual-modulus prescaler (P/P + 1). The

A (6-bit) and B (13-bit) counters, in conjunction with the dual-

modulus prescaler (P/P + 1), implement an N divider

(N = BP + A). In addition, the 14-bit reference counter

(R counter), allows selectable REFIN frequencies at the PFD

input. A complete PLL (phase-locked loop) can be implemented

if the synthesizer is used with an external loop filter and 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.
