18QHTF21-32.860-PD

Oscillators Overview

The 18QHTF21-32.860-PD is a quartz crystal oscillator manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a frequency of 32.860 MHz with an LVCMOS output logic level. The device supports a supply voltage of 1.8V and includes a standby (power down) function for energy management. It is housed in a compact 4-SMD, no lead package with dimensions of 2.0x1.6 mm.

Oscillators Feature Summary

• LVCMOS output interface
• Standby power down capability
• Quartz crystal construction

Oscillators Applications

• General purpose clock generation
• Embedded system timing
• Consumer electronics

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 4-SMD no-lead package footprint matches the PCB layout specifications to guarantee proper soldering and mechanical stability during assembly.

Oscillators Selection Notes

Select this component when a low-profile, surface-mount oscillator is required for 1.8V logic systems. The choice depends on the need for a standard LVCMOS signal and the availability of a standby mode to reduce power consumption during idle periods. Consider the physical size constraints of the application to ensure the 2.0x1.6 mm package fits within the designated area.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which focuses on small form-factor oscillators. The series typically offers various frequencies and voltage options, catering to modern portable devices where space and power efficiency are critical. The 'PD' suffix indicates the inclusion of a power-down feature.

Oscillators Replacement Considerations

Direct substitutes include other 18QHTF21 variants with compatible frequencies such as 18QHTF21-32.768-PD or 18QHTF21-33.333-PD, provided the frequency difference is acceptable. Cross-referencing with similar 2.0x1.6mm LVCMOS oscillators from other manufacturers requires verification of pin compatibility and electrical parameters.
