Wideband Synthesizer with Integrated VCO

ADF4350

FEATURES

GENERAL DESCRIPTION

Output frequency range: 137.5 MHz to 4400 MHz

Fractional-N synthesizer and integer-N synthesizer

Low phase noise VCO

Programmable divide-by-1/-2/-4/-8/-16 output

Typical rms jitter: 0.5 ps rms

Power supply: 3.0 V to 3.6 V

Logic compatibility: 1.8 V

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

Programmable output power level

RF output mute function

The ADF4350 allows implementation of fractional-N or

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

if used with an external loop filter and external reference

frequency.

The ADF4350 has an integrated voltage controlled oscillator

(VCO) with a fundamental output frequency ranging from

2200 MHz to 4400 MHz. In addition, divide-by-1/2/4/8 or 16

circuits allow the user to generate RF output frequencies as low

as 137.5 MHz. For applications that require isolation, the RF

output stage can be muted. The mute function is both pin- and

software-controllable. An auxiliary RF output is also available,

which can be powered down if not in use.

3-wire serial interface

Analog and digital lock detect

Switched bandwidth fast-lock mode

Cycle slip reduction

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

interface. The device operates with a power supply ranging

from 3.0 V to 3.6 V and can be powered down when not in use.

APPLICATIONS

Wireless infrastructure (W-CDMA, TD-SCDMA, WiMAX,

GSM, PCS, DCS, DECT)

Test equipment

Wireless LANs, CATV equipment

Clock generation
