LMX2532LQ0967

Overview

The LMX2532LQ0967 is a PLLatinum frequency synthesizer system from National Semiconductor, featuring an integrated Phase-Locked Loop (PLL) and Voltage-Controlled Oscillator (VCO). Designed for CDMA and PCS applications, this RF IC operates with a reference frequency of 170.76 MHz. It is housed in a compact 28-WQFN package measuring 5x5 mm, suitable for space-constrained wireless communication devices requiring precise frequency synthesis.

Feature Summary

• Integrates PLL and VCO into a single system
• Optimized for CDMA and PCS wireless standards
• Compact 28-WQFN surface-mount packaging

Applications

• CDMA mobile communication systems
• PCS network infrastructure equipment
• Wireless transceiver modules

Procurement Notes

Verify component authenticity through authorized National Semiconductor or Texas Instruments channels. Confirm the specific suffix LQ0967 matches the required 170.76 MHz reference specification. Check RoHS compliance status as indicated in official documentation, noting potential non-compliance variants. Ensure storage conditions adhere to moisture sensitivity level requirements prior to assembly.

Selection Notes

Select this model when a dedicated frequency synthesizer with integrated VCO is required for CDMA or PCS bands. The fixed 170.76 MHz reference input dictates system clock architecture. Consider the 28-WQFN footprint for PCB layout constraints. Compare against other LMX2532 variants if different reference frequencies or package types are needed for the specific design.

Part Context

This component belongs to the PLLatinum family of frequency synthesizers by National Semiconductor, now part of Texas Instruments. The series provides high-performance solutions for RF applications. The LQ0967 variant specifically targets the 170.76 MHz reference configuration within the broader LMX2532 product line, offering integrated synthesis capabilities.

Replacement Considerations

The LMX2532LQ1065 serves as a direct functional substitute within the same series, differing primarily in its reference frequency specification of 367.20 MHz instead of 170.76 MHz. Verify that the system clock requirements align with the alternative's reference input before substitution.
