STW81103AT

Overview

The STW81103AT is an integrated RF frequency synthesizer featuring a multi-band voltage-controlled oscillator (VCO) designed for general-purpose applications. It operates within a frequency range of 2.5 GHz to 5 GHz, providing high performance and integration levels suitable for industrial environments. The device utilizes an integer-N phase-locked loop architecture to generate stable output signals. It is housed in a 28-VFQFPN package, offering a compact solution for RF signal generation requirements.

Feature Summary

• Integrated multi-band voltage-controlled oscillator for broad frequency coverage
• Integer-N phase-locked loop architecture for precise frequency synthesis
• High-performance design optimized for industrial application stability

Applications

• Industrial automation systems requiring precise clock generation
• Automotive electronic systems needing reliable RF signal sources
• Commercial equipment utilizing general-purpose RF synthesizers

Procurement Notes

Verify the specific datasheet revision and ordering information directly with STMicroelectronics or authorized distributors to ensure compatibility with current production standards. Confirm that the 28-VFQFPN package matches your PCB layout requirements. Ensure that the operating temperature range specified in the official documentation aligns with your intended industrial or automotive environment constraints before finalizing procurement decisions.

Selection Notes

Select this component when a general-purpose RF synthesizer with a 2.5 GHz to 5 GHz range is required. It is suitable for designs needing integrated VCO functionality without external components. Consider the 28-VFQFPN package size for space-constrained layouts. Evaluate the need for industrial-grade performance specifications if deploying in harsh environments compared to commercial-grade alternatives.

Part Context

This part belongs to the STW8110x series of PLL clock generators developed by STMicroelectronics. These devices are engineered for single-output applications, supporting control interfaces such as I2C or SPI via associated GUI software tools. The series targets markets demanding high integration and low power consumption for RF signal processing tasks.

Replacement Considerations

Check for direct substitutes within the STW8110x family, such as the STW81101, ensuring pinout and functional compatibility. Verify that alternative parts meet the same 2.5 GHz to 5 GHz frequency range and package requirements. Consult official cross-reference lists from STMicroelectronics for validated replacements.
