18QHTF21-23.512-PD

Oscillators Overview

The 18QHTF21-23.512-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a frequency of 23.512 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and features an enable/disable control interface. It is housed in a compact 4-SMD, No Lead package designed for surface-mount applications.

Oscillators Feature Summary

• Supports standby mode via power down functionality
• Utilizes LVCMOS output logic for digital interfacing
• Features enable/disable control capability

Oscillators Applications

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

Oscillators Procurement Notes

Verify the specific suffix 'PD' indicates the power down feature as documented. Confirm the operating temperature range and load capacitance requirements against the target design specifications. Ensure the 4-SMD no lead package dimensions match the PCB footprint constraints. Cross-reference the manufacturer part number to avoid confusion with non-power-down variants.

Oscillators Selection Notes

Select this component when a 23.512 MHz clock source with low voltage operation is required. The LVCMOS output is suitable for standard digital logic families. Consider the power down feature if energy efficiency during idle states is a design priority. Verify compatibility with the host controller's input voltage levels before integration.

Oscillators Part Context

This model belongs to the 18QHTF21 series of standard crystal oscillators from Mercury Electronics. The series offers various frequencies and voltage options. The 'PD' suffix distinguishes it from other variants by including power down capabilities. It is part of a broader lineup of SMD oscillators used in consumer and industrial electronics.

Oscillators Replacement Considerations

Direct substitutes include other 23.512 MHz LVCMOS oscillators with identical 1.8V supply and 4-SMD no lead packages. Verify pinout compatibility and electrical parameters such as jitter and phase noise. Check if the replacement supports the same enable/disable control scheme.
