18QHTF32-16.666666-PD

Oscillators Overview

The 18QHTF32-16.666666-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a nominal frequency of 16.666666 MHz and utilizes LVCMOS output logic levels. The device is designed for low-power applications, featuring a supply voltage of 1.8V. A key functional characteristic is the inclusion of a standby or power-down mode capability, allowing for energy conservation when the oscillator is not actively required. The component is housed in a compact 4-SMD, No Lead package, suitable for surface-mount assembly processes.

Oscillators Feature Summary

• Supports LVCMOS output signal compatibility
• Includes standby or power-down functionality
• Operates on a 1.8V supply voltage

Oscillators Applications

• Precision timing applications requiring specific frequency generation
• Low power consumption electronic systems
• Surface-mount circuit board assemblies

Oscillators Procurement Notes

Verify the exact frequency tolerance and load capacitance requirements against your system design specifications before procurement. Confirm that the 1.8V operating voltage aligns with your power supply rails. Ensure the 4-SMD no-lead package dimensions are compatible with your PCB footprint and manufacturing capabilities. Cross-reference the suffix 'PD' to confirm power-down feature availability if critical for your application.

Oscillators Selection Notes

Select this component when a precise 16.666666 MHz clock source is required with minimal power usage. The LVCMOS interface ensures compatibility with standard digital logic families. Consider the integrated power-down feature for battery-operated devices or systems requiring active sleep states. The small form factor makes it suitable for space-constrained designs.

Oscillators Part Context

Mercury Electronics Ind. Co. Ltd has been manufacturing frequency control products since 1973, establishing itself as a pioneer in the quartz crystal industry in Taiwan. The company produces a wide range of components including quartz crystals, clock oscillators, TCXOs, VCTCXOs, VCXOs, OCXOs, and monolithic crystal filters.

Oscillators Replacement Considerations

Other variants within the 18QHTF32 series, such as those with different frequency suffixes (e.g., -21.0961, -9.1665), share similar packaging and electrical characteristics but differ in output frequency. Ensure any substitute matches the 16.666666 MHz requirement exactly. Verify that alternative sources support the same 1.8V LVCMOS specification and standby functionality.
