3512-52

Overview

The pSemi 3512-52 is a general-purpose RF IC prescaler designed for high-frequency signal processing applications. It operates within a frequency range of 0Hz to 1.5GHz, providing a fixed divide-by-4 ratio for input signals. The component is housed in a compact SC-70-6 surface-mount package, facilitating integration into space-constrained circuit designs. This prescaler serves as a critical interface between high-speed RF front-ends and lower-frequency digital logic or mixers, ensuring accurate frequency division without requiring external tuning components.

Feature Summary

• Provides a fixed divide-by-4 frequency division ratio for input signals
• Operates across a wide frequency range from DC to 1.5GHz
• Utilizes a compact SC-70-6 surface-mount package for efficient board layout

Applications

• RF front-end frequency translation stages
• Local oscillator signal conditioning
• Frequency synthesizer reference dividers
• Wireless communication system down-conversion interfaces

Procurement Notes

Verify the obsolete product status before procurement planning, as availability may be limited to stock or last-time-buy options. Confirm that the SC-70-6 package dimensions align with existing PCB footprints. Ensure that the 1.5GHz upper frequency limit meets the specific operational requirements of the target application, as this component is not suitable for frequencies exceeding its specified range.

Selection Notes

Select this component when a fixed divide-by-4 ratio is required for signals up to 1.5GHz. Consider the SC-70-6 package size if space constraints are a primary design factor. Evaluate the need for general-purpose prescaler functionality versus programmable alternatives. Verify that the input signal levels and impedance matching requirements are compatible with standard RF prescaler interfaces provided by this device.

Part Context

The 3512-52 belongs to the pSemi family of RF miscellaneous integrated circuits and modules. These components are typically utilized in wireless infrastructure and consumer electronics to manage high-frequency signals. As a prescaler, it bridges the gap between analog RF domains and digital processing sections, offering a reliable solution for frequency reduction in systems where simplicity and wide bandwidth are prioritized over programmability.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, direct replacements may require functional equivalence analysis with other divide-by-4 prescalers in similar packages. Consult manufacturer archives or authorized distributors for potential cross-reference data.
