Microwave Wideband Synthesizer

with Integrated VCO

Data Sheet

ADF4372

FEATURES

GENERAL DESCRIPTION

RF output frequency range: 62.5 MHz to 16,000 MHz

Fractional-N synthesizer and integer-N synthesizer

High resolution 39-bit fractional modulus

Typical spurious f_PFD: −90 dBc

Integrated rms jitter: 38 fs (1 kHz to 100 MHz)

Normalized phase noise floor: −234 dBc/Hz

The ADF4372 allows implementation of fractional-N or integer-N

phase-locked loop (PLL) frequency synthesizers when used with

an external loop filter and an external reference frequency. The

wideband microwave voltage controlled oscillator (VCO) design

allows frequencies from 62.5 MHz to 16 GHz to be generated.

The ADF4372 has an integrated VCO with a fundamental output

frequency ranging from 4000 MHz to 8000 MHz. In addition, the

VCO frequency is connected to a divide by 1, 2, 4, 8, 16, 32, or 64

circuit that allows the user to generate radio frequency (RF)

output frequencies as low as 62.5 MHz at RF8x. A frequency

multiplier at RF16x generates from 8 GHz to 16 GHz. RFAUX8x

duplicates the frequency range of RF8x or permits direct access to

the VCO output. To suppress the unwanted products of frequency

multiplication, a harmonic filter exists between the multiplier and

the output stage of RF16x.

_PFDoperation to 250 MHz

Reference input frequency operation to 600 MHz

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

62.5 MHz to 8,000 MHz output at RF8x and RFAUX8x

8,000 MHz to 16,000 MHz output at RF16x

Lock time approximately 3 ms with automatic calibration

Lock time <30 μs with autocalibration bypassed, typical

Analog and digital power supplies: 3.3 V typical

VCO supply voltage: 3.3 V and 5 V

RF output mute function

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

The ADF4372 operates with analog and digital power supplies

ranging from 3.15 V to 3.45 V, and 5 V for the VCO power

supply. The ADF4372 also contains hardware and software

power-down modes.
