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

Oscillators Feature Summary

• Supports enable/disable functionality for power management
• Utilizes LVCMOS output interface
• Compact surface-mount design

Oscillators Applications

• General timing circuits
• Embedded systems requiring low-voltage operation
• Portable electronic devices

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Ensure the 1.8V supply voltage aligns with your system's power rails. Confirm that the enable pin logic level is compatible with your microcontroller or driver outputs to prevent unintended oscillation states.

Oscillators Selection Notes

Select this component when a precise 3.1152 MHz clock signal is required in space-constrained applications. The 1.8V operating voltage makes it suitable for modern low-power digital logic families. Consider the enable feature if dynamic power saving is necessary during idle periods in the target application.

Oscillators Part Context

This part belongs to the H21 series of SMD oscillators from Mercury Electronics. The series typically offers standard frequency options with LVCMOS outputs. The 'OE' suffix indicates the inclusion of an enable pin, distinguishing it from continuous-output variants within the same package footprint.

Oscillators Replacement Considerations

Direct substitutes must match the 3.1152 MHz frequency, 1.8V supply, and 4-SMD no-lead package. Verify pin compatibility for the enable function. Other manufacturers offering similar footprints should be evaluated for equivalent electrical characteristics and thermal performance.
