Integer-N/Fractional-N PLL Synthesizer

Data Sheet

ADF4155

FEATURES

GENERAL DESCRIPTION

Input frequency range: 500 MHz to 8000 MHz

Fractional-N synthesizer and integer-N synthesizer

Phase frequency detector (PFD) up to 125 MHz

High resolution 38-bit modulus

The ADF4155 allows implementation of fractional-N or

integer-N phase-locked loop (PLL) frequency synthesizers

when used with an external loop filter, external voltage

controlled oscillator (VCO), and external reference frequency.

Separate charge pump supply (V_P) allows extended tuning

voltage in 5 V systems

Programmable divide by 1, 2, 4, 8, 16, 32, or 64 output

Differential and single-ended reference inputs

Power supply: 3.3 V 5%

The ADF4155 is for use with external VCO parts up to an

8 GHz operating frequency. The high resolution programmable

modulus allows synthesis of exact frequencies with 0 Hz error.

The VCO frequency can be divided by 1, 2, 4, 8, 16, 32, or 64 to

allow the user to generate RF output frequencies as low as

7.8125 MHz.

Logic compatibility: 1.8 V

Programmable dual-modulus prescaler (P) of 4/5 or 8/9

Programmable output power level

3-wire serial interface

Control of all on-chip registers is through a simple 3-wire

interface. The device operates with a nominal power supply of

3.3 V 5% and can be powered down when not in use.

Analog and digital lock detect

APPLICATIONS

The ADF4155 is available in a 24-lead, 4 mm × 4 mm LFCSP

package.
