18QHTF21-26.880-PD

Oscillators Overview

The 18QHTF21-26.880-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 26.88 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features a power-down standby function. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm.

Oscillators Feature Summary

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

Oscillators Applications

• General purpose timing circuits
• Embedded systems requiring precise clock signals
• Portable electronic devices due to low voltage requirements

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Ensure that the 1.8V supply rail is stable and within the specified operating range to maintain oscillator performance. Confirm that the PCB footprint matches the 4-SMD No Lead package dimensions for proper assembly.

Oscillators Selection Notes

Select this component when a small form factor and low power consumption are critical. The 1.8V operating voltage makes it suitable for modern low-power digital interfaces. Consider the 26.88 MHz frequency specifically if required for audio or video sampling rates where this value provides integer division ratios.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which focuses on miniature surface-mount oscillators. The series typically offers various frequencies and output types, all sharing a common 2.0x1.6mm footprint. This specific model represents a standard XO variant with power management features.

Oscillators Replacement Considerations

Direct replacements must match the 26.88 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 Electronics stock is unavailable.
