18QHTF21-26.806-PD

Oscillators Overview

The 18QHTF21-26.806-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a frequency of 26.806 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and includes a standby or power-down function. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm.

Oscillators Feature Summary

• Supports low-voltage operation at 1.8V
• Integrates standby and power-down functionality
• Provides LVCMOS output signal compatibility

Oscillators Applications

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

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target application design before procurement. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the 4-SMD no-lead package footprint matches the PCB layout constraints. Check for any specific operating temperature range limitations required by the end-use environment.

Oscillators Selection Notes

Select this component when a precise 26.806 MHz clock source is required for low-power digital applications. The choice is driven by the need for LVCMOS compatibility and a small 2.0x1.6mm form factor. Consider the standby feature if power management during idle states is critical. Validate that the manufacturer's specifications meet the electromagnetic interference and stability needs of the circuit.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series offers various frequencies within a standardized 4-SMD package. The 'PD' suffix indicates the inclusion of power-down capabilities. Mercury Electronics specializes in quartz crystal manufacturing, providing frequency control solutions for electronic devices.

Oscillators Replacement Considerations

Direct substitutes must match the 26.806 MHz frequency, 1.8V supply, LVCMOS output, and 2.0x1.6mm package. Verify pinout compatibility and electrical characteristics such as phase noise and jitter. Cross-reference with other manufacturers offering similar SMD oscillators with identical form factors and voltage levels.
