ZL40813/DCE

Overview

The ZL40813/DCE is a fixed modulus divider designed for high-frequency applications, operating within the X-band range of 10.5GHz to 13.5GHz. It functions as a divide-by-8 prescaler, providing stable frequency division for RF systems requiring precise signal processing in this specific band. The component is housed in an 8-SOIC package and is engineered to support low-noise performance requirements typical of satellite communication infrastructure.

Feature Summary

• Fixed modulus division capability with a constant divide-by-8 ratio
• Operational frequency coverage within the X-band spectrum from 10.5GHz to 13.5GHz
• Integrated design suitable for use as a prescaler in high-frequency signal chains

Applications

• High-frequency local oscillator signal sources for VSAT systems
• RF prescaler stages in satellite communication ground stations
• Frequency synthesis circuits requiring fixed division ratios in the X-band

Procurement Notes

Verify the exact manufacturer specifications against the official datasheet before integration. Confirm that the 8-SOIC package dimensions and pinout align with your PCB layout requirements. Ensure the input frequency range strictly falls within the 10.5GHz to 13.5GHz operational limits to guarantee correct divide-by-8 functionality and signal integrity.

Selection Notes

Select this component when a fixed divide-by-8 ratio is required for frequencies between 10.5GHz and 13.5GHz. It is appropriate for designs needing a compact prescaler solution in X-band applications. Consider the 8-SOIC package constraints and ensure the system can accommodate the specific voltage and current requirements defined in the electrical characteristics section of the documentation.

Part Context

This device belongs to the family of high-frequency dividers used in RF and microwave systems. It serves as a critical building block for frequency synthesis, particularly in scenarios where a stable, fixed division ratio is preferred over programmable alternatives. Its design supports the generation of clean local oscillator signals for downstream mixing or modulation processes.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing circuit designs if considering alternative components, ensuring they meet the same X-band frequency and divide-by-8 ratio specifications.
