18QHTF21-29.412-PD

Oscillators Overview

The 18QHTF21-29.412-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 29.412 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and includes a standby or power-down function for energy management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm.

Oscillators Feature Summary

• Integrates LVCMOS output logic for digital interface compatibility
• Features a standby mode to reduce power consumption during idle periods
• Utilizes a surface-mount 4-SMD no-lead package for automated assembly

Oscillators Applications

• Digital signal processing systems requiring precise clock timing
• Communication equipment utilizing standard frequency references
• Embedded controllers needing low-voltage oscillator solutions

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply rail is stable within the operational limits defined in the official datasheet. Ensure the PCB footprint matches the 2.0mm x 1.6mm SMD package dimensions to guarantee proper soldering and mechanical stability during operation.

Oscillators Selection Notes

Select this component when a 29.412 MHz reference is required with LVCMOS outputs. Consider the 1.8V operating voltage constraint and the availability of the power-down feature for power-sensitive designs. Evaluate the thermal performance and frequency stability needs against the standard specifications provided by the manufacturer for this series.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which focuses on low-profile surface-mount oscillators. The series typically offers various frequencies with standardized packaging. The 'PD' suffix indicates the inclusion of a power-down control pin, distinguishing it from continuous-operation variants within the same physical footprint family.

Oscillators Replacement Considerations

Direct replacements must match the 29.412 MHz frequency, LVCMOS output type, 1.8V supply, and 4-SMD 2.0x1.6mm package. Verify pinout compatibility and electrical characteristics such as jitter and phase noise if strict timing performance is required.
