The device supports a supply voltage of 1.8V and includes an enable/disable control function for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm.

Feature Summary

• LVCMOS output interface
• Enable/Disable control pin
• Compact surface-mount package

Applications

• General-purpose timing circuits
• Microcontroller clock sources
• Low-power embedded systems

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before ordering. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD no-lead footprint matches your PCB layout constraints. Request the official datasheet from the manufacturer to validate electrical characteristics and reliability standards.

Selection Notes

Select this component when a precise 1.0152 MHz reference is required in space-constrained designs. The LVCMOS output ensures compatibility with standard digital logic families. The enable feature allows for dynamic power savings in battery-operated applications. Consider the operating temperature range specified in the datasheet to ensure stability under environmental conditions.

Part Context

This oscillator belongs to the 18QHTF21 series from Mercury Electronics, which focuses on low-profile timing solutions. The series typically offers various frequencies within a small form factor. The 'OE' suffix indicates the presence of an enable pin, distinguishing it from models without control functionality. This family targets consumer electronics and portable devices requiring reliable clock signals.

Replacement Considerations

Direct substitutes include other 1.0152 MHz LVCMOS oscillators in 2.0x1.6mm packages with enable pins. Verify pinout compatibility and voltage levels before swapping. Alternative frequencies may require retuning associated circuits. Consult manufacturer cross-reference lists for verified equivalents.
