LMX2820RTCT

Overview

The LMX2820RTCT is a wideband RF synthesizer from Texas Instruments, operating within an output frequency range of 45 MHz to 22.6 GHz. It supports input frequencies between 5 MHz and 1.4 GHz. The device functions on a 3.3 V supply voltage, with operational limits from 3.15 V to 3.45 V. It consumes 500 mA during operation and is rated for temperatures from -40°C to +85°C. Packaged in a 48-VQFN (7x7 mm) format, it utilizes Silicon technology.

Feature Summary

• Generates any frequency across the 45 MHz to 22.6 GHz wideband spectrum
• Integrates phase synchronization capabilities for signal alignment
• Supports JESD204B interface standards for digital connectivity
• Achieves rapid frequency calibration within less than 5 microseconds

Applications

• Wireless infrastructure base stations
• Point-to-point microwave radio systems
• Test and measurement equipment requiring high-frequency synthesis
• Satellite communication ground stations

Procurement Notes

Verify the specific suffix RTCT corresponds to the required tape and reel packaging configuration. Confirm that the 48-VQFN package dimensions align with your PCB footprint requirements. Ensure the 3.3 V power supply design accommodates the 500 mA current draw. Check moisture sensitivity levels for proper storage and reflow soldering profiles before assembly.

Selection Notes

Select this component when a single-chip solution is needed for ultra-wideband frequency generation up to 22.6 GHz. It is suitable for designs requiring integrated phase synchronization and JESD204B support without external multiplexers. Consider the 500 mA current consumption for power budget calculations. The VQFN package is appropriate for compact, surface-mount applications.
