LMX2532 Datasheet Frequency Synthesizer System

Manufacturer: Texas Instruments

Overview: LMX2522, LMX2532 .ti. SNWS009B – MARCH 2003 – REVISED APRIL 2013 LMX2522/LMX2532 PLLatinum™ Frequency Synthesizer System with Integrated VCOs Check for Samples: LMX2522,.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

LMX2522 and LMX2532 are highly integrated, high performance, 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 handsets.

Using a proprietary digital phase locked loop technique, LMX2522 and LMX2532 generate very stable, low noise local oscillator signals for up and down conversion in wireless munications devices.

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.
