Dual Low Power PLL

Frequency Synthesizer

ADF4212L

Data Sheet

FEATURES

GENERAL DESCRIPTION

I_DDtotal: 7.5 mA

Bandwidth RF/IF: 2.4 GHz/1.0 GHz

2.7 V to 3.3 V power supply

Separate V_Pallows extended tuning voltage

Programmable dual modulus prescaler

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

Programmable charge pump currents

3-wire serial interface

The ADF4212L is a dual frequency synthesizer that can be used

to implement local oscillators (LO) in the up-conversion and

down-conversion sections of wireless receivers and transmitters.

It can provide the LO for both the RF and IF sections. It consists

of a low noise digital phase frequency detector (PFD), 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 (12-bit) counters, in conjunction with the dual

modulus prescaler (P/P + 1), implement an N divider (N = BP +

A). In addition, the 15-bit reference counter (R counter) allows

selectable REF_INfrequencies at the PFD input. A complete phase-

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

with external loop filters and voltage controlled oscillators (VCOs).

APPLICATIONS

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

interface with 1.8 V compatibility. The devices operate with a

power supply ranging from 2.7 V to 3.3 V and can be powered

down when not in use.
