18QHTF21-29.4612-PD

Oscillators Overview

The 18QHTF21-29.4612-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 29.4612 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, designed for surface-mount applications requiring precise timing signals.

Oscillators Feature Summary

• LVCMOS output logic interface
• Integrated standby and power-down functionality
• Surface-mount 4-SMD no-lead package design

Oscillators Applications

• General purpose digital timing circuits
• Embedded systems requiring low voltage operation
• Portable electronic devices with power constraints

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your system design before procurement. Confirm that the 1.8V supply voltage aligns with your target platform's power rails. Ensure the 4-SMD no-lead footprint matches your PCB layout specifications to guarantee proper soldering and mechanical stability during assembly.

Oscillators Selection Notes

Select this component when a standard XO with LVCMOS outputs is required for 1.8V systems. Consider the 4-SMD no-lead form factor for space-constrained designs. Evaluate the need for standby capabilities if power efficiency is critical. Compare alternative frequencies within the same series if the exact 29.4612 MHz rate does not match the application clock requirements.

Oscillators Part Context

This part belongs to the Mercury Electronics 18QHTF21 series of standard crystal oscillators. The series typically offers various frequencies with LVCMOS outputs and 1.8V operation. The 'PD' suffix indicates the inclusion of power-down features. This family targets applications needing reliable timing in small surface-mount packages.

Oscillators Replacement Considerations

Direct substitutes include other 18QHTF21 series variants with identical pinout and electrical characteristics but different frequencies, such as 18QHTF21-30.300-PD or 18QHTF21-51.200-PD, provided the frequency difference is acceptable for the system.
