18QHTF21-29.1621-PD

Oscillators Overview

The 18QHTF21-29.1621-PD is a quartz crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 29.1621 MHz with an LVCMOS output logic level. The device requires a supply voltage of 1.8V and features a Standby (Power Down) function for energy management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm.

Oscillators Feature Summary

• Supports Low Voltage CMOS (LVCMOS) output signaling
• Includes Standby mode capability for power reduction

Oscillators Applications

• General electronic timing circuits
• Embedded system clock generation
• Portable devices requiring low power consumption

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD footprint matches your PCB layout constraints to guarantee proper assembly and electrical connectivity.

Oscillators Selection Notes

Select this component when a precise 29.1621 MHz reference is required in space-constrained designs. The choice depends on the necessity for LVCMOS compatibility and the availability of a 1.8V power source. Consider the physical size limitations and the need for standby functionality in your application architecture.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series offers various frequencies within a small form factor. The suffix PD indicates the inclusion of a power-down feature, distinguishing it from standard continuous-operation variants in the product line.

Oscillators Replacement Considerations

Direct replacements must match the 29.1621 MHz frequency, 1.8V operation, LVCMOS output, and 4-SMD package dimensions. Verify pinout compatibility and thermal characteristics if substituting with components from other manufacturers.
