18QHTF21-29.490-PD

Oscillators Overview

The 18QHTF21-29.490-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 29.49 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and features a standby or power-down function for energy management. It is housed in a compact 4-SMD, no-lead package with dimensions of 2.0x1.6mm. This component is designed for applications requiring precise timing signals within space-constrained electronic systems.

Oscillators Feature Summary

• Integrates LVCMOS output logic for standard digital interface compatibility
• Includes standby capability to reduce power consumption during inactive periods
• Utilizes a small form factor surface-mount package for PCB integration

Oscillators Applications

• General purpose timing clock generation
• Embedded system synchronization
• Consumer electronics timing references

Oscillators Procurement Notes

Verify the specific operating temperature range and load capacitance requirements against the target application design before procurement. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the 4-SMD no-lead package footprint matches the PCB layout silkscreen and solder mask definitions to prevent assembly defects.

Oscillators Selection Notes

Select this model when a 29.49 MHz frequency is strictly required alongside low-voltage operation. Consider the standby feature if power efficiency is critical. Compare physical dimensions against available board space. Evaluate the LVCMOS output swing against the input thresholds of the receiving logic circuitry to ensure signal integrity.

Oscillators Part Context

This part belongs to the 18QHTF series of quartz crystal oscillators from Mercury Electronics. The series offers various frequencies and supply voltages. The suffix PD indicates the inclusion of a power-down control pin. The manufacturer specializes in frequency control products including crystals and oscillators, providing standardized timing solutions for industrial and consumer markets.

Oscillators Replacement Considerations

Check datasheets for compatible parts such as the 18QHTF21-51.200-PD or 18QHTF21-96.768-PD if frequency adjustments are permissible. Verify that substitute components maintain the same 1.8V supply requirement and LVCMOS output type. Ensure the replacement maintains the 4-SMD no-lead package profile for mechanical compatibility.
