3QHTF22-56.250-PD

Oscillators Overview

The 3QHTF22-56.250-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 56.25 MHz and utilizes LVCMOS output logic levels. The device is designed for a supply voltage of 3.3V and features a standby mode for power down functionality. It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount assembly on printed circuit boards.

Oscillators Feature Summary

• Supports low-voltage CMOS output signaling
• Includes standby control for power management
• Utilizes lead-free surface mount packaging

Oscillators Applications

• Digital signal processing systems
• Communication equipment clocking
• Computer peripheral interfaces

Oscillators Procurement Notes

Verify the specific operating temperature range and load capacitance requirements against the target application design before procurement. Confirm that the 3.3V supply rail stability meets the oscillator's specifications to ensure frequency accuracy. Ensure the PCB layout accommodates the 4-SMD footprint dimensions precisely to avoid soldering defects during assembly.

Oscillators Selection Notes

Select this component when a precise 56.25 MHz reference is required for LVCMOS-compatible digital circuits. Consider the 3.3V supply constraint and the need for power-down capability as primary selection criteria. Evaluate the physical space constraints to ensure the 4-SMD package fits within the designated area on the motherboard or daughter card.

Oscillators Part Context

This part belongs to the Mercury Electronics 3QHTF22 series of standard XO oscillators. The series offers various frequencies with consistent LVCMOS outputs and 3.3V operation. The -PD suffix indicates the inclusion of a power-down pin or function, distinguishing it from basic continuous-operation variants within the same family.

Oscillators Replacement Considerations

Direct replacements must match the 56.25 MHz frequency, LVCMOS output type, 3.3V supply, and 4-SMD no-lead package. Verify pinout compatibility and thermal characteristics. Cross-reference with other manufacturers offering identical electrical parameters and mechanical dimensions for equivalent performance.
