RF PLL Frequency Synthesizers

ADF4110/ADF4111/ADF4112/ADF4113

GENERAL DESCRIPTION

FEATURES

The ADF4110 family of frequency synthesizers can be used

to implement local oscillators in the upconversion 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 (6-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).

ADF4110: 550 MHz

ADF4111: 1.2 GHz

ADF4112: 3.0 GHz

ADF4113: 4.0 GHz

2.7 V to 5.5 V Power Supply

Separate Charge Pump Supply (V_P) Allows Extended

Tuning Voltage in 3 V Systems

Programmable Dual Modulus Prescaler 8/9, 16/17,

32/33, 64/65

Programmable Charge Pump Currents

Programmable Antibacklash Pulsewidth

3-Wire Serial Interface

Analog and Digital Lock Detect

Hardware and Software Power-Down Mode

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.
