LMX2522/LMX2532

™

PLLatinum Frequency Synthesizer System with

Integrated VCOs

General Description

Features

n Small Size

LMX2522 and LMX2532 are highly integrated, high perfor-

mance, low power frequency synthesizer systems optimized

for Korean PCS (K-PCS) with GPS and Korean Cellular

(K-Cellular) with GPS, CDMA (1xRTT, IS-95) mobile hand-

sets. Using a proprietary digital phase locked loop tech-

nique, LMX2522 and LMX2532 generate very stable, low

noise local oscillator signals for up and down conversion in

wireless communications devices.

Small 5.0 mm x 5.0 mm x 0.75 mm 28-Pin LLP Package

n RF/GPS Synthesizer System

Integrated RF VCO

Integrated GPS VCO

Integrated Loop Filter

Low Spurious, Low Phase Noise Fractional-N RF PLL

Based on 11-bit Delta Sigma Modulator

10 kHz Frequency Resolution

n IF Synthesizer System

Integer-N IF PLL

Programmable Charge Pump Current Levels

Programmable Frequencies

n Supports Various Reference Oscillator Frequencies

19.20/19.68 MHz

n Fast Lock Time: 500 µs

n Low Current Consumption

17 mA at 2.8 V

LMX2522 and LMX2532 include a RF voltage controlled

oscillator (VCO), a GPS VCO, a loop filter, and a fractional-N

RF PLL based on a delta sigma modulator. In concert these

blocks form a closed loop RF and GPS synthesizer system.

LMX2522 supports the Korean PCS band with GPS and

LMX2532 supports the Korean Cellular band with GPS.

LMX2522 and LMX2532 include an Integer-N IF PLL also.

For more flexible loop filter designs, the IF PLL includes a

4-level programmable charge pump. Together with an exter-

nal VCO and loop filter, LMX2522 and LMX2532 make a

complete closed loop IF synthesizer system.

n 2.7 V to 3.3 V Operation

Serial data is transferred to the device via a three-wire

MICROWIRE interface (DATA, LE, CLK).

n Digital Filtered Lock Detect Output

n Hardware and Software Power Down Control

Operating supply voltage ranges from 2.7 V to 3.3 V.

LMX2502 and LMX2512 feature low current consumption:

17 mA at 2.8 V.

Applications

n Korean PCS CDMA Systems with GPS

n Korean Cellular CDMA Systems with GPS

LMX2522 and LMX2532 are available in a 28-pin leadless

leadframe package (LLP).
