18QHTF21-32.673-PD

Oscillators Overview

The 18QHTF21-32.673-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 32.673 MHz with LVCMOS output logic. The device supports 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 2.0x1.6mm.

Oscillators Feature Summary

• LVCMOS output logic for digital interface compatibility
• Integrated standby and power-down functionality
• Compact 4-SMD no-lead surface mount package

Oscillators Applications

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

Oscillators Procurement Notes

Verify the specific order code against the manufacturer's official documentation to ensure correct frequency and package variant. Confirm that the 'PD' suffix corresponds to the required power-down feature as specified in the datasheet. Cross-reference the part number with authorized distributors to validate authenticity and current availability status before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a precise 32.673 MHz reference. The small 2.0x1.6mm footprint makes it suitable for space-constrained designs. Ensure the application environment supports the operating temperature range defined in the official specifications. Verify that LVCMOS logic levels match the receiving input requirements of the target circuitry.

Oscillators Part Context

This model belongs to the Mercury Electronics 18QHTF21 series of surface-mount oscillators. The series typically offers various frequencies within a standardized 4-SMD package format. The 'PD' designation indicates the inclusion of power management features, distinguishing it from standard continuous-operation variants within the same physical form factor family.

Oscillators Replacement Considerations

Direct substitutes must match the 32.673 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify pinout compatibility and electrical characteristics against the original datasheet before substitution.
