18QHTF21-23.760-PD

Oscillators Overview

The 18QHTF21-23.760-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 23.76 MHz and utilizes LVCMOS output logic. The device is designed for low-voltage applications, requiring a supply voltage of 1.8V. It features a power-down capability, allowing the oscillator to enter a standby mode to reduce power consumption when not in use. The component is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm, suitable for surface-mount assembly on printed circuit boards.

Oscillators Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes power-down functionality for standby mode operation
• Designed for low-voltage 1.8V supply requirements

Oscillators Applications

• General clock signal generation in electronic circuits
• Timing reference sources for digital systems
• Embedded devices requiring precise frequency control

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your design specifications before procurement. Ensure that the 1.8V supply voltage aligns with your system's power rails. Confirm that the 4-SMD No Lead package footprint matches your PCB layout constraints. Check for any specific handling or storage conditions recommended by the manufacturer for quartz-based components.

Oscillators Selection Notes

Select this component when a stable 23.76 MHz clock source is required for LVCMOS-compatible digital logic. Consider the 1.8V operating voltage as a primary constraint for power supply design. The integrated power-down feature makes it suitable for battery-operated or energy-efficient applications where standby current reduction is critical. Evaluate the small 2.0x1.6mm package size for space-constrained designs.

Oscillators Part Context

This part belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronics Ind. Co. Ltd. The series offers various frequencies within a standardized 4-SMD No Lead package. Mercury Electronic is a Taiwan-based manufacturer specializing in frequency-control products, including quartz crystals, TCXOs, and VCTCXOs, with a history dating back several decades.

Oscillators Replacement Considerations

Other parts in the 18QHTF21 series with different frequencies may serve as functional replacements if the timing requirement changes. Equivalent oscillators from other manufacturers must match the 23.76 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD No Lead package dimensions to ensure mechanical and electrical compatibility.
