LMX2505LQX1321

Overview

The LMX2505LQX1321 is a PLLatinum™ series integrated circuit functioning as a high-performance PLL frequency synthesizer with an integrated VCO. Manufactured by Texas Instruments, this component operates within a supply voltage range of 2.5V to 3.3V and features a nominal supply current of 10mA. It is designed for applications requiring precise frequency synthesis at a specific output frequency of 1321MHz. The device utilizes Silicon technology and is housed in a 28-terminal WQFN package. It supports operation across a temperature range extending from -40°C to +85°C, ensuring reliability in various signal processing environments.

Feature Summary

• Integrates a Phase-Locked Loop (PLL) and Voltage-Controlled Oscillator (VCO) into a single compact chip
• Delivers high-performance frequency synthesis capabilities suitable for demanding communication systems
• Operates on a standard low-voltage power supply ranging from 2.5V to 3.3V

Applications

• Communication system signal processing
• RF wireless integrated circuits
• Frequency synthesis modules

Procurement Notes

Verify the exact suffix and terminal count against official Texas Instruments documentation to ensure compatibility. Confirm that the 28-terminal WQFN package matches your PCB footprint requirements. Check for RoHS compliance status if environmental regulations apply to your manufacturing process. Ensure the operating temperature range meets your specific environmental conditions.

Selection Notes

Select this component when a fixed-frequency synthesizer solution near 1.321GHz is required. Consider the integrated VCO design for simplified board layout compared to discrete solutions. Evaluate the 28-terminal WQFN package size constraints against available board space. Verify that the 10mA nominal current consumption fits within your system's power budget.
