3QHTF21-67.600-PD

Oscillators Overview

The 3QHTF21-67.600-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 67.6 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 3.3V 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

• Standard XO configuration with LVCMOS output interface
• Integrated standby and power-down functionality
• Compact 4-SMD No Lead surface-mount package

Oscillators Applications

• General-purpose digital circuit timing

Oscillators Procurement Notes

Verify the specific operating temperature range and load capacitance requirements against your design specifications before procurement. Confirm that the 3.3V supply voltage aligns with your system's power rails. Ensure the 4-SMD No Lead footprint matches your PCB layout constraints to guarantee proper soldering and mechanical stability during assembly.

Oscillators Selection Notes

Select this component when a stable 67.6 MHz reference is required with low-power standby capabilities. The LVCMOS output is suitable for standard CMOS logic families. Consider the 3.3V operating voltage as a primary constraint. The SMD form factor is ideal for high-density board designs where space is limited compared to through-hole alternatives.

Oscillators Part Context

This part belongs to the 3QHTF21 series of quartz-based oscillators from Mercury Electronics. The series offers various frequencies within the standard XO category. The 'PD' suffix typically indicates the inclusion of power-down control features. This model provides a specific 67.6 MHz solution within the broader portfolio of frequency control products offered by the manufacturer.

Oscillators Replacement Considerations

Direct substitutes include other 67.6 MHz LVCMOS oscillators in 4-SMD packages from compatible manufacturers. Verify pinout compatibility and electrical parameters such as rise/fall times and duty cycle. Ensure the replacement also supports the 3.3V supply and standby functions if these are critical to the design.
