18QHTF21-37.888-PD

Oscillators Overview

The 18QHTF21-37.888-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 37.888 MHz with LVCMOS output logic. The device requires a 1.8V supply voltage and features a Standby (Power Down) control function. It is housed in a compact 4-SMD, No Lead package.

Oscillators Feature Summary

• LVCMOS output logic for digital interface compatibility
• Standby power down mode for energy efficiency
• Compact 4-SMD no lead surface mount package

Oscillators Applications

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

Oscillators Procurement Notes

Verify the specific ordering suffix PD indicates the Standby function against the official datasheet. Confirm the 1.8V supply requirement matches the target circuit design. Ensure the 4-SMD package footprint aligns with the PCB layout specifications before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a low voltage 1.8V operation is required alongside a standby feature. The LVCMOS output suits digital logic families. Consider the 37.888 MHz frequency specifically for applications requiring this exact timing reference rather than standard frequencies.

Oscillators Part Context

This part belongs to the Mercury Electronics 18QHTF21 series of surface mount oscillators. The series offers various frequencies and control options like Enable/Disable or Standby modes within a small form factor suitable for space-constrained electronic designs.

Oscillators Replacement Considerations

Check for direct substitutes from Mercury Electronics with identical pinout and electrical parameters. Verify that alternative parts support the same 1.8V supply and LVCMOS output levels to ensure functional compatibility.
