18QHTF21-19.600-PD

Oscillators Overview

The 18QHTF21-19.600-PD is a 19.6 MHz crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a supply voltage of 1.8V and features LVCMOS output signals. The device is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm. A key functional characteristic is the inclusion of a standby or power-down mode for energy management.

Oscillators Feature Summary

• LVCMOS output signal interface
• Integrated standby power-down capability
• Compact 4-SMD no-lead surface mount package

Oscillators Applications

• Portable electronic devices requiring low power consumption
• Embedded systems utilizing 1.8V logic levels
• Consumer electronics with space-constrained PCB layouts

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your system design before procurement. Confirm that the 1.8V supply voltage aligns with your target platform's power rails. Ensure the 2.0x1.6 mm footprint matches your PCB silkscreen and copper pad design to prevent assembly issues.

Oscillators Selection Notes

Select this component when a 19.6 MHz clock source is required within a strict 1.8V operating environment. The choice is driven by the need for a small form factor suitable for dense circuit boards. Consider the standby feature if power efficiency during idle states is a critical design constraint.

Oscillators Part Context

This part belongs to the Mercury 18QHTF21 series of standard crystal oscillators. The series offers various frequencies while maintaining consistent electrical characteristics and package dimensions. It represents a solution for applications needing precise timing without the complexity of programmable clocks.

Oscillators Replacement Considerations

Direct substitutes must match the 19.6 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify pin compatibility and thermal performance before swapping manufacturers.
