RF PLL Frequency Synthesizers

ADF4116/ADF4117/ADF4118

GENERAL DESCRIPTION

FEATURES

The ADF4116 family of frequency synthesizers can be used

to implement local oscillators in the up-conversion and down-

conversion sections of wireless receivers and transmitters. They

consist of a low-noise digital PFD (Phase Frequency Detector),

a precision charge pump, a programmable reference divider,

programmable A and B counters and a dual-modulus prescaler

(P/P+1). The A (5-bit) and B (13-bit) counters, in conjunction

with the dual modulus prescaler (P/P+1), implement an N

divider (N = BP+A). In addition, the 14-bit reference counter

(R Counter), allows selectable REFIN frequencies at the PFD

input. A complete PLL (Phase-Locked Loop) can be imple-

mented if the synthesizer is used with an external loop ﬁlter and

VCO (Voltage Controlled Oscillator).

ADF4116: 550 MHz

ADF4117: 1.2 GHz

Control of all the on-chip registers is via a simple 3-wire interface.

The devices operate with a power supply ranging from 2.7 V to

5.5 V and can be powered down when not in use.
