1521H-45.1584K18DTSTK

Overview

The 1521H-45.1584K18DTSTK is a standard crystal oscillator (XO) manufactured by Suzhou Hangjing Elec&Tech Co., Ltd. It operates at a fixed frequency of 45.1584 MHz and utilizes HCMOS output logic levels. The device is designed for surface-mount applications, featuring a compact 4-SMD, No Lead package configuration. It functions with a supply voltage of 1.8V and includes an enable/disable control pin for power management flexibility. This component serves as a precise clock source for digital circuits requiring stable frequency generation.

Feature Summary

• HCMOS output interface for digital signal compatibility
• Integrated enable/disable functionality for power control
• Compact 4-SMD no-lead surface mount package design

Applications

• General purpose clock generation in embedded systems
• Timing reference for microcontroller units
• Signal processing components in consumer electronics

Procurement Notes

Verify the exact part number suffix to ensure correct packaging and tape/reel specifications. Confirm that the 1.8V supply voltage aligns with your system's power rails. Check for RoHS compliance status if required by your manufacturing standards. Ensure the HCMOS output voltage levels are compatible with the receiving logic inputs. Validate the operating temperature range against your environmental requirements before finalizing the procurement order.

Selection Notes

Select this model when a 45.1584 MHz clock signal is specifically required. The 1.8V operating voltage makes it suitable for low-power portable devices. The enable/disable feature allows for dynamic power management strategies. Consider the small form factor of the 4-SMD package for space-constrained PCB layouts. Ensure the HCMOS output swing matches the input requirements of the downstream circuitry.

Part Context

This component belongs to the 1521H series of quartz oscillators from Suzhou Hangjing Elec&Tech. The series focuses on providing reliable frequency control solutions using quartz resonator technology. These oscillators are designed for mass production in consumer electronics and industrial applications. The manufacturer emphasizes precision supply chain management and rigorous testing to maintain consistent quality across the product line.

Replacement Considerations

The 1521H-45.1584K18DTSK is a related variant within the same series. Verify if the K suffix indicates a difference in packaging or tolerance compared to the DTSTK version. Cross-reference electrical parameters such as load capacitance and drive level to ensure functional equivalence. Confirm that the pinout and mechanical dimensions are identical to avoid PCB redesign.
