18QHTF21-14.850-PD

Oscillators Overview

The 18QHTF21-14.850-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a nominal frequency of 14.85 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 for energy management. It is housed in a compact 4-SMD, no-lead package with dimensions of 2.0mm x 1.6mm. This component is suitable for applications requiring precise clock signals in space-constrained electronic designs.

Oscillators Feature Summary

• Supports low-voltage operation at 1.8V
• Integrates standby mode for power reduction
• Utilizes LVCMOS output interface
• Features a compact surface-mount footprint

Oscillators Applications

• General-purpose digital clock generation
• Embedded system timing references
• Portable electronics requiring low power consumption
• Communication module synchronization

Oscillators Procurement Notes

Verify the specific suffix 'PD' against official Mercury Electronics documentation to confirm the presence of the power-down feature. Ensure the operating temperature range meets your environmental requirements. Cross-reference the 4-SMD no-lead package dimensions with your PCB layout constraints. Confirm that the 1.8V supply voltage aligns with your system's power rails before finalizing the procurement order.

Oscillators Selection Notes

Select this component when a 14.85 MHz clock signal is required with minimal board space. The 1.8V supply requirement makes it suitable for modern low-power digital circuits. Consider the LVCMOS output compatibility with your target logic family. The integrated standby function offers an advantage for battery-operated devices where power efficiency is critical during idle periods.

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 supply voltages. The 'P' suffix often denotes a specific tape-and-reel packaging option, while 'D' may indicate a specific lead-free or RoHS-compliant variant. Check the full datasheet for series-wide specifications regarding aging and stability.

Oscillators Replacement Considerations

Direct substitutes must match the 14.85 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify pinout compatibility if replacing with components from other manufacturers. Ensure the replacement part supports the same standby functionality if power management is a design constraint.
