Dual RF/IF PLL Frequency Synthesizers

ADF4210/ADF4211/ADF4212/ADF4213

GENERAL DESCRIPTION

FEATURES

The ADF4210/ADF4211/ADF4212/ADF4213 is a dual frequency

synthesizer that can be used to implement local oscillators (LO)

in the upconversion and downconversion sections of wireless

receivers and transmitters. They can provide the LO for both

the RF and IF sections. They consist of a low-noise digital PFD

(Phase Frequency Detector), a precision charge pump, a pro-

grammable reference divider, programmable A and B Counters

and a dual-modulus prescaler (P/P + 1). The A (6-bit) and B

(12-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 implemented if the synthesizer is used with

an external loop ﬁlter and VCO (Voltage Controlled Oscillators).

ADF4210: 550 MHz/1.2 GHz

ADF4211: 550 MHz/2.0 GHz

ADF4212: 1.0 GHz/2.7 GHz

ADF4213: 1.0 GHz/3 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

RF and IF: 8/9, 16/17, 32/33, 64/65

Programmable Charge Pump Currents

3-Wire Serial Interface

Analog and Digital Lock Detect

Fastlock Mode

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 V and can be powered down when not in use.
