18QHTF21-38.13986-PD

Oscillators Overview

The 18QHTF21-38.13986-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 38.13986 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features a standby or power-down function to manage energy consumption. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm. This component serves as a precise timing source for electronic circuits requiring stable clock signals.

Oscillators Feature Summary

• Provides precise timing via LVCMOS output logic
• Includes standby and power-down functionality
• Compact 4-SMD no-lead surface mount package

Oscillators Applications

• General purpose clock signal generation
• Embedded system timing references
• Digital circuit synchronization

Oscillators Procurement Notes

Verify the specific frequency tolerance and operating temperature range against the official datasheet before integration. Confirm that the 1.8V supply voltage aligns with the target system design. Ensure the 4-SMD package footprint matches the PCB layout requirements. Check for any specific handling instructions regarding the no-lead soldering process.

Oscillators Selection Notes

Select this model when a low-voltage 1.8V operation is required alongside a standard LVCMOS interface. The small 2.0x1.6 mm package makes it suitable for space-constrained designs. Consider the standby feature if power management during idle states is a priority. Validate that the 38.13986 MHz frequency meets the specific timing needs of the application.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies within a standardized small outline package. The series supports both standard and spread-spectrum options, though this specific variant is defined as a standard XO. It complements other Mercury timing components like TCXOs and VCTCXOs for broader frequency control solutions.

Oscillators Replacement Considerations

Direct substitutes must match the 38.13986 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify pinout compatibility and electrical specifications such as load capacitance and drive strength. Cross-reference with distributor databases for equivalent parts from other manufacturers offering identical form factors.
