Fractional-N Frequency Synthesizer

Data Sheet

ADF4153

FEATURES

GENERAL DESCRIPTION

RF bandwidth to 4 GHz

2.7 V to 3.3 V power supply

The ADF4153 is a fractional-N frequency synthesizer

that implements local oscillators in the upconversion

and downconversion sections of wireless receivers and

transmitters. It consists of a low noise digital phase

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

a programmable reference divider. There is a Σ-Δ based

fractional interpolator to allow programmable fractional-N

division. The INT, FRAC, and MOD registers define an

overall N divider (N = (INT + (FRAC/MOD))). In addition,

the 4-bit reference counter (R counter) allows selectable

REFIN frequencies at the PFD input. A complete phase-

locked loop (PLL) can be implemented if the synthesizer is

used with an external loop filter and a voltage controlled

oscillator (VCO).

Separate V_Pallows extended tuning voltage

Y version available: −40°C to +125°C

Programmable fractional modulus

Programmable charge pump currents

3-wire serial interface

Analog and digital lock detect

Power-down mode

Pin-compatible with ADF4110/ADF4111/ADF4112/ADF4113

and ADF4106

Consistent RF output phase

Loop filter design possible with ADIsimPLL

Qualified for automotive applications

A simple 3-wire interface controls all on-chip registers.

The device operates with a power supply ranging from

2.7 V to 3.3 V and can be powered down when not in use.
