18QHTF21-7.00375-OE

Overview

The 18QHTF21-7.00375-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 7.00375 MHz with an LVCMOS output logic level. The device requires a supply voltage of 1.8V and features enable/disable functionality for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm. The component supports an operating temperature range from -40°C to 85°C and maintains a frequency stability of ±50ppm.

Feature Summary

• Supports enable/disable control via 1.8V supply
• Provides LVCMOS output signal
• Compact 4-SMD no-lead surface mount package

Applications

• General purpose clock generation
• Embedded systems timing
• Consumer electronics circuits

Procurement Notes

Verify the specific suffix (OE) against the manufacturer's current documentation to ensure compatibility with required enable/disable pin configurations. Confirm that the 1.8V supply requirement aligns with the target system's voltage rails. Check the lead-free status and RoHS compliance if environmental regulations apply to the final assembly. Ensure the 4-SMD footprint matches the PCB design constraints.

Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside precise timing needs. The LVCMOS output is suitable for direct interfacing with digital logic families. Consider the ±50ppm stability for applications where moderate frequency accuracy is sufficient. The small form factor makes it ideal for space-constrained designs requiring surface mount technology.

Part Context

This part belongs to the 18QHTF21 series of oscillators from Mercury Electronic. The series typically includes various frequencies and packages. The 'OE' suffix likely denotes specific packaging or tape-and-reel options compared to other variants like 'PD'. These oscillators are designed for general electronic applications requiring stable clock signals.

Replacement Considerations

Direct substitutes may include other 18QHTF21 series parts with compatible frequencies and packages. Verify electrical parameters such as supply voltage and output logic before substitution. Consult the manufacturer's cross-reference list for approved alternatives.
