Data Sheet

ADF4159

FEATURES

GENERAL DESCRIPTION

RF bandwidth to 13 GHz

High and low speed FMCW ramp generation

The ADF4159 is a 13 GHz, fractional-N frequency synthesizer

with modulation and both fast and slow waveform generation

25-bit fixed modulus allows subhertz frequency resolution

PFD frequencies up to 110 MHz

capability. The part uses a 25-bit fixed modulus, allowing subhertz

frequency resolution.

Normalized phase noise floor of −224 dBc/Hz

FSK and PSK functions

Sawtooth, triangular, and parabolic waveform generation

Ramp superimposed with FSK

Ramp with 2 different sweep rates

Ramp delay, frequency readback, and interrupt functions

Programmable phase control

2.7 V to 3.45 V analog power supply

1.8 V digital power supply

The ADF4159 consists of a low noise digital phase frequency

detector (PFD), a precision charge pump, and a programmable

reference divider. The Σ-Δ-based fractional interpolator allows

programmable fractional-N division. The INT and FRAC registers

define an overall N divider as N = INT + (FRAC/2²⁵).

The ADF4159 can be used to implement frequency shift keying

(FSK) and phase shift keying (PSK) modulation. Frequency sweep

modes are also available to generate various waveforms in the

frequency domain, for example, sawtooth and triangular wave-

forms. The ADF4159 features cycle slip reduction circuitry, which

enables faster lock times without the need for modifications to

the loop filter.

Programmable charge pump currents

3-wire serial interface

Digital lock detect

ESD performance: 3000 V HBM, 1000 V CDM

Control of all on-chip registers is via a simple 3-wire interface. The

ADF4159 operates with an analog power supply in the range of

2.7 V to 3.45 V and a digital power supply in the range of 1.62 V

to 1.98 V. The device can be powered down when not in use.
