3QHTF22-139.999999-PD

Oscillators Overview

The 3QHTF22-139.999999-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 139.999999 MHz with an LVCMOS output signal. The device requires a 3.3V supply voltage and features a Standby (Power Down) control function for power management. It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount applications.

Oscillators Feature Summary

• Provides stable LVCMOS clock signals at a precise frequency
• Includes standby functionality to reduce power consumption during idle states
• Designed for surface-mount integration via a leadless SMD package

Oscillators Applications

• Digital signal processing systems requiring precise timing
• Communication equipment utilizing high-frequency clock sources
• Embedded systems needing low-power standby modes

Oscillators Procurement Notes

Verify the specific ordering suffix 'PD' confirms the Standby (Power Down) feature rather than Enable/Disable variants. Ensure the 4-SMD No Lead package dimensions match the target PCB footprint. Confirm that the 3.3V supply requirement aligns with the system's voltage rails before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a fixed 139.999999 MHz frequency is strictly required. The choice depends on the necessity for LVCMOS logic levels and the availability of a standby control pin. Consider the thermal and electrical characteristics of the 4-SMD package relative to the host board layout constraints.

Oscillators Part Context

This model belongs to the 3QHTF22 series from Mercury Electronics, which specializes in quartz crystal frequency control products. The manufacturer has decades of experience in Taiwan's crystal industry. This specific part represents a standard XO variant within their portfolio of precision timing solutions.

Oscillators Replacement Considerations

Direct substitutes include other 3QHTF22 series parts with identical frequencies but different control suffixes, such as the -OE variant for Enable/Disable functions. Cross-reference with other manufacturers offering 139.999999 MHz LVCMOS oscillators in 4-SMD packages if supply chain constraints exist.
