Overview

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
Separate charge pump supply (VP) 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%
Logic compatibility: 1.8 V
Programmable dual-modulus prescaler (P) of 4/5 or 8/9
Programmable output power level
3-wire serial interface
Analog and digital lock detect

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.

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.

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.

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