18QHTF21-29.970-OE

Oscillators Overview

The 18QHTF21-29.970-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 29.97 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and includes an enable/disable control pin for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm.

Oscillators Feature Summary

• Integrates LVCMOS output logic for digital interface compatibility
• Features an enable/disable control function for power optimization
• Utilizes a leadless surface-mount package for automated assembly

Oscillators Applications

• General clock signal generation in embedded systems
• Timing reference for low-voltage digital circuits
• Consumer electronics requiring compact oscillators

Oscillators Procurement Notes

Verify the specific suffix 'OE' indicates the enable/disable functionality as documented. Confirm the operating temperature range and load capacitance requirements against the target circuit design. Ensure the 1.8V supply voltage aligns with the system's power rails before procurement to avoid functional incompatibility.

Oscillators Selection Notes

Select this component when a 29.97 MHz timing source is required for LVCMOS-compatible logic families. The choice is driven by the need for a small 2.0x1.6 mm footprint and integrated power control. Consider the 1.8V supply constraint and ensure the application supports the standard XO performance characteristics defined by the manufacturer.

Oscillators Part Context

This part belongs to the 18QHTF21 series of quartz crystal oscillators from Mercury Electronics. The series offers various frequencies within a standardized 4-SMD no-lead form factor. The 'OE' suffix specifically denotes the inclusion of an output enable feature, distinguishing it from standard continuous-output variants in the same physical package family.

Oscillators Replacement Considerations

Direct substitutes must match the 29.97 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Verify that any alternative part includes the enable/disable pin configuration to maintain system power management capabilities.
