18QHTF21-35.318-OE

Oscillators Overview

The 18QHTF21-35.318-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 35.318 MHz and utilizes LVCMOS output logic. The device is designed for low-voltage applications, requiring a supply voltage of 1.8V. It features an enable/disable control function to manage power consumption. The component is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm.

Oscillators Feature Summary

• LVCMOS output logic for digital interface compatibility
• Integrated enable/disable control functionality
• Compact 4-SMD no-lead surface mount package

Oscillators Applications

• General clock signal generation in electronic circuits
• Low-voltage digital system timing references
• Portable devices requiring small form factor oscillators

Oscillators Procurement Notes

Verify the specific ordering suffix '-OE' against the manufacturer's current documentation to ensure correct pinout and enable/disable configuration. Confirm that the 1.8V supply voltage aligns with the target system design requirements before procurement. Cross-reference the package dimensions with PCB footprint specifications to ensure mechanical compatibility.

Oscillators Selection Notes

Select this component when a precise 35.318 MHz reference is required for LVCMOS-compatible digital logic. The choice is driven by the need for a small 2.0x1.6mm footprint and low-power operation at 1.8V. Ensure the application supports the enable/disable feature if dynamic power management is necessary. Verify temperature range requirements against standard commercial specifications.

Oscillators Part Context

This part belongs to the Mercury Electronics 18QHTF21 series of surface-mount crystal oscillators. The series typically offers various frequencies and supply voltages within a standardized small outline package. The 'OE' suffix likely denotes specific electrical or packaging variations defined by the manufacturer for this particular frequency point.

Oscillators Replacement Considerations

Direct substitutes include other 35.318 MHz LVCMOS oscillators in 4-SMD packages from manufacturers such as Epson, NDK, or SiTime. Ensure replacement parts match the 1.8V supply requirement and physical dimensions. Verify output drive strength and load capacitance specifications to maintain signal integrity.
