Dual Low Power PLL

Frequency Synthesizer

ADF4212L

GENERAL DESCRIPTION

FEATURES

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 con-

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

precision charge pump, a programmable reference divider, pro-

grammable 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 imple-

mented if the synthesizer is used with external loop filters and

VCOs (Voltage Controlled Oscillators).

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

Analog and Digital Lock Detect

Fastlock Mode

Power-Down Mode

20-Lead TSSOP and 20-Lead MLF Chip Scale Package

APPLICATIONS

Wireless Handsets (GSM, PCS, DCS, CDMA, WCDMA)

Base Stations for Wireless Radio (GSM, PCS, DCS,

CDMA, WCDMA)

Wireless LANS

Cable TV Tuners (CATV)

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 2.6 V to 3.3 V and can be powered down

when not in use.
