18QHTF21-16.640-PD

Oscillators Overview

The 18QHTF21-16.640-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 16.64 MHz and utilizes LVCMOS output logic levels. The device is designed for a supply voltage of 1.8V and includes a standby or power-down function to manage energy consumption. It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount applications requiring precise timing signals.

Oscillators Feature Summary

• LVCMOS output interface for digital logic compatibility
• Integrated standby mode for power management
• Compact 4-SMD no-lead surface mount packaging

Oscillators Applications

• General purpose clock signal generation
• Digital circuit timing references
• Embedded system clock sources

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your design specifications before ordering. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD footprint matches your PCB layout constraints. Request the official datasheet from Mercury Electronics for detailed electrical characteristics and reliability data.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a standard LVCMOS output. The integrated power-down feature makes it suitable for battery-operated devices where standby current reduction is critical. Consider the 16.64 MHz frequency specifically if it matches your system clock divider requirements or communication protocol standards.

Oscillators Part Context

This part belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronics. The series offers various frequencies and supports LVCMOS outputs. Mercury Electronics is a established manufacturer of frequency control products, including quartz crystals and oscillators, with a history dating back to 1973.

Oscillators Replacement Considerations

Other parts in the 18QHTF21 series with different frequencies may serve as functional replacements if the timing requirement changes. Direct substitutes must match the 1.8V supply, LVCMOS output type, and 4-SMD package dimensions. Verify pinout compatibility before swapping.
