18QHTF21-26.670-PD

Oscillators Overview

The 18QHTF21-26.670-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 26.67 MHz and utilizes LVCMOS output logic levels. The device functions with a supply voltage of 1.8V and features a standby or power-down capability for energy management. It is housed in a compact 4-SMD, no-lead package with dimensions of 2.0x1.6mm.

Oscillators Feature Summary

• Supports low-voltage operation at 1.8V
• Includes standby and power-down functionality
• Provides LVCMOS signal output compatibility

Oscillators Applications

• Battery-powered electronic devices
• Portable consumer electronics
• General-purpose digital timing circuits

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply rail stability meets the oscillator's operational specifications. Ensure the PCB footprint matches the 2.0x1.6mm SMD package dimensions to prevent assembly issues during manufacturing.

Oscillators Selection Notes

Select this component when a precise 26.67 MHz clock source is required for low-power applications. The LVCMOS interface ensures compatibility with standard digital logic families. The integrated power-down feature makes it suitable for systems requiring active standby modes to conserve battery life in portable equipment.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which focuses on small-form-factor oscillators. The series typically offers various frequencies within a standardized 2.0x1.6mm package. These components are designed to replace larger through-hole crystals or older surface-mount oscillators in space-constrained modern electronic designs.

Oscillators Replacement Considerations

Direct substitutes must match the 26.67 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Verify pinout compatibility and thermal characteristics. Cross-reference with other manufacturers offering similar low-profile oscillators if Mercury stock is unavailable.
