LMX2515LQ1321/NOPB

Overview

The LMX2515LQ1321/NOPB is a PLLatinum frequency synthesizer with an integrated PLL and VCO. It operates at a fixed output frequency of 1321 MHz using PDC RF technology. The device functions within a supply voltage range of 2.5 V to 3.3 V, drawing a typical supply current of 17.8 mA. It is housed in a 28-WQFN (5x5) package and supports operation temperatures up to 85°C. This component is RoHS compliant and lead-free.

Feature Summary

• Integrates both phase-locked loop and voltage-controlled oscillator circuits into a single chip
• Utilizes PLLatinum series architecture for frequency synthesis applications
• Designed for surface-mount installation in compact electronic systems

Applications

• RF communication systems requiring fixed frequency generation
• Wireless infrastructure equipment components
• Test and measurement instrumentation modules

Procurement Notes

Verify part authenticity through authorized Texas Instruments channels or certified distributors. Confirm the specific suffix matches the requested specifications. Check for obsolescence status as this component may be discontinued. Ensure storage conditions comply with moisture sensitivity level requirements before assembly. Validate that the received package type matches the 28-WQFN form factor.

Selection Notes

Select this component when a fixed 1321 MHz output is required without external tuning. Consider the integrated design benefits for reducing board space compared to discrete solutions. Evaluate the 17.8 mA current consumption against system power budgets. Ensure the operating temperature range meets environmental requirements. Verify compatibility with existing control interfaces for the PLLatinum series.

Part Context

This device belongs to the PLLatinum family of frequency synthesizers from Texas Instruments. It represents a specialized solution for fixed-frequency applications rather than programmable synthesizers. The integration of PLL and VCO reduces external component count. The WQFN package facilitates high-density PCB layouts. It serves as a building block for RF signal generation chains.
