18QHTF21-3.6567-PD

Oscillators Overview

The 18QHTF21-3.6567-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a fixed frequency of 3.6567 MHz and utilizes LVCMOS output logic. The device is designed for low-power applications, featuring a supply voltage of 1.8V and an integrated standby or power-down function to minimize energy consumption during idle periods. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm, suitable for space-constrained surface-mount designs.

Oscillators Feature Summary

• Integrates LVCMOS output logic for direct digital interface compatibility
• Supports standby mode to reduce power consumption when inactive
• Utilizes a leadless SMD package for automated surface-mount assembly

Oscillators Applications

• Low-power portable electronic devices requiring precise timing
• Embedded systems utilizing LVCMOS-compatible processors
• Consumer electronics with strict size constraints

Oscillators Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure the correct frequency and package variant. Confirm that the 1.8V supply requirement aligns with the target system's voltage rails. Check for any updated environmental compliance certifications required for the destination market before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a stable 3.6567 MHz clock signal is required for LVCMOS interfaces. Ensure the design accommodates the 1.8V operating voltage and utilizes the 2.0x1.6mm footprint. Consider the standby feature if power management is critical for the application lifecycle.

Oscillators Part Context

This oscillator belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz frequency control products. The series offers various frequencies within a standardized small outline package format, providing consistent mechanical and electrical characteristics across different model variants for easier design reuse.

Oscillators Replacement Considerations

Direct substitutes include other 18QHTF21 series models with identical pinout and dimensions but different frequencies, such as the 18QHTF21-3.500-PD or 18QHTF21-48.7056-PD, provided the system timing requirements allow for frequency adjustment.
