18QHTF21-16.838-PD

Oscillators Overview

The 18QHTF21-16.838-PD is an active crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a nominal frequency of 16.838 MHz and utilizes LVCMOS output logic levels. The device supports a supply voltage range that includes 1.8V operation with a standby power-down mode for energy efficiency. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm, designed for surface-mount assembly on printed circuit boards.

Oscillators Feature Summary

• Supports low-voltage operation with integrated standby functionality
• Utilizes standard LVCMOS output interface for digital compatibility
• Employed in compact surface-mount packaging for space-constrained designs

Oscillators Applications

• Digital signal processing systems requiring precise clock synchronization
• Communication equipment utilizing standard logic interfaces
• Embedded control units needing low-power standby modes

Oscillators Procurement Notes

Verify the specific operating voltage requirements against the official datasheet to ensure compatibility with the target system's power rails. Confirm that the LVCMOS output levels align with the receiving logic family. Ensure the PCB footprint matches the 2.0x1.6 mm SMD no-lead package specifications to prevent assembly errors during manufacturing.

Oscillators Selection Notes

Select this component when a stable 16.838 MHz reference is required within tight spatial constraints. Consider the 1.8V standby capability if power management is critical. Validate that the LVCMOS output swing meets the input threshold requirements of downstream components before finalizing the design.

Oscillators Part Context

This model belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronic. The series offers various frequency options within a standardized 2.0x1.6 mm form factor. The 'PD' suffix typically indicates power-down or standby capabilities, distinguishing it from continuous-operation variants within the same physical package family.

Oscillators Replacement Considerations

Direct substitutes must match the 16.838 MHz frequency, LVCMOS output type, and 2.0x1.6 mm SMD package. Verify equivalent electrical characteristics including supply voltage and current consumption. Cross-reference with other manufacturers offering similar small-form-factor oscillators only if pinout and electrical specs are identical.
