18QHTF21-17.600-PD

Oscillators Overview

The 18QHTF21-17.600-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd, operating at a nominal frequency of 17.6 MHz. It utilizes LVCMOS output logic and supports a supply voltage of 1.8V. The device features a power-down mode for standby applications. It is housed in a compact 4-SMD, no-lead package, suitable for surface-mount assembly in space-constrained electronic designs requiring precise clock signals.

Oscillators Feature Summary

• Supports low-voltage LVCMOS output logic for digital interface compatibility
• Includes power-down functionality to reduce consumption during standby periods
• Utilizes a leadless SMD package for automated surface-mount processing

Oscillators Applications

• Digital system clock generation
• Communication equipment timing
• Embedded processor synchronization

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the PCB footprint matches the 4-SMD no-lead package dimensions provided in the official datasheet to prevent assembly errors.

Oscillators Selection Notes

Select this component when a fixed 17.6 MHz clock source is required with low power consumption capabilities. Consider the LVCMOS output level compatibility with downstream logic families. Evaluate the thermal performance and operating temperature range to ensure reliability within the intended environmental conditions of the final application.

Oscillators Part Context

This part belongs to the 18QHTF21 series of high-frequency oscillators from Mercury Electronics. The series offers various frequency options with consistent packaging and electrical characteristics. The 'PD' suffix indicates the inclusion of a power-down control feature, distinguishing it from standard continuous-operation variants within the same form factor family.

Oscillators Replacement Considerations

Direct substitutes include other 17.6 MHz LVCMOS oscillators in 4-SMD packages with 1.8V operation. Verify pinout compatibility and electrical specifications such as jitter and phase noise before substitution.
