18QHTF21-33.780-PD

Oscillators Overview

The 18QHTF21-33.780-PD is a 33.78 MHz crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It utilizes LVCMOS output logic and operates at a supply voltage of 1.8V. The device features a power-down function via a standby control input. It is housed in a 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm.

Oscillators Feature Summary

• Supports LVCMOS output logic for standard digital interfacing
• Includes standby mode for power-down capability
• Utilizes surface-mount SMD package for compact integration

Oscillators Applications

• General clock signal generation in electronic circuits
• Integration into systems requiring low-voltage operation
• Applications necessitating power management through standby modes

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the PCB footprint matches the 2.0x1.6mm SMD package dimensions to guarantee proper soldering and mechanical stability during assembly processes.

Oscillators Selection Notes

Select this component when a precise 33.78 MHz reference is required in space-constrained designs. The choice is driven by the need for low-voltage compatibility and integrated power management. Consider the package size relative to available board real estate and ensure the LVCMOS interface meets the driving requirements of the downstream logic components.

Oscillators Part Context

This part belongs to the Mercury 18QHTF series of quartz crystal oscillators. The series offers various frequencies within a small form factor. The 'PD' suffix indicates the inclusion of a power-down feature, distinguishing it from standard continuous-operation variants within the same physical package family.

Oscillators Replacement Considerations

Direct substitutes include other 33.78 MHz LVCMOS oscillators in 2.0x1.6mm packages with 1.8V operation and standby functionality. Verify pinout compatibility and electrical specifications before substitution.
