18QHTF21-22.080-PD

Oscillators Overview

The 18QHTF21-22.080-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 22.08 MHz and utilizes LVCMOS output logic levels. The device is designed for low-power applications, featuring a supply voltage of 1.8V and a standby power-down mode to reduce energy consumption during idle periods. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm, suitable for surface-mount assembly on printed circuit boards.

Oscillators Feature Summary

• Supports low-voltage operation at 1.8V with integrated power-down functionality
• Delivers standard LVCMOS signal outputs for digital interface compatibility
• Utilizes a lead-free 4-SMD no-lead surface mount package design

Oscillators Applications

• General-purpose timing reference for embedded systems
• Clock source for consumer electronics requiring low power
• Digital signal processing circuits needing stable frequency input

Oscillators Procurement Notes

Verify the specific suffix 'PD' indicates the power-down feature when sourcing replacements. Confirm that the 1.8V supply requirement matches the target system's voltage rails. Ensure the 4-SMD footprint aligns with the existing PCB layout. Check RoHS compliance status if environmental regulations apply to the final assembly.

Oscillators Selection Notes

Select this component when a precise 22.08 MHz clock is required alongside minimal power consumption. The 1.8V operating voltage makes it suitable for modern low-voltage logic families. Consider the small 2.0x1.6 mm package size for space-constrained designs. Evaluate the need for active standby modes to extend battery life in portable devices.

Oscillators Part Context

This part belongs to the QHTF series of quartz crystal oscillators from Mercury Electronics. The series typically offers various frequencies and voltage options within similar small form factors. Mercury Electronics specializes in frequency control products, including crystals and oscillators, serving the global electronics market with precision timing solutions.

Oscillators Replacement Considerations

Direct substitutes include other 22.08 MHz LVCMOS oscillators in 4-SMD packages with 1.8V operation. Verify pinout compatibility and electrical specifications before swapping. Alternative parts must support the same standby functionality if power management is critical.
