18QHTF21-13.529-PD

Overview

The 18QHTF21-13.529-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 13.529 MHz and utilizes LVCMOS output logic. The device is designed for low-voltage applications with a supply voltage of 1.8V. It features a Standby mode for power management and is housed in a compact 4-SMD, No Lead package.

Feature Summary

• Supports Standby (Power Down) functionality for energy efficiency
• Utilizes LVCMOS output logic for digital interface compatibility
• Operates on a 1.8V supply voltage

Applications

• Battery-powered portable devices
• Low-power consumer electronics
• Digital signal processing circuits

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your system design before procurement. Ensure the 1.8V supply rail stability meets the oscillator's specifications. Confirm that the 4-SMD No Lead package dimensions fit within the designated PCB footprint area to avoid assembly issues.

Selection Notes

Select this component when a 13.529 MHz clock source is required for LVCMOS-compatible digital systems. The 1.8V operating voltage makes it suitable for modern low-power integrated circuits. Consider the Standby feature if power conservation during idle periods is a critical design constraint for the target application.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz timing solutions. The series includes various frequencies and output types. Mercury Electronics is a Taiwan-based manufacturer established in 1973, focusing on crystals, oscillators, and filters for global electronic markets.

Replacement Considerations

Direct substitutes include other 13.529 MHz LVCMOS oscillators in 4-SMD packages with 1.8V operation. Verify pinout compatibility and electrical parameters such as phase noise and jitter before substitution.
