18QHTF21-26.100-PD

Oscillators Overview

The 18QHTF21-26.100-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 26.1 MHz and utilizes LVCMOS output logic. The device is designed for low-power applications, featuring a 1.8V supply voltage with an integrated standby or power-down mode to reduce energy consumption during idle periods. It is housed in a compact 4-SMD, no-lead package, suitable for surface-mount assembly on printed circuit boards. This component provides precise clock signals for digital systems requiring stable timing references.

Oscillators Feature Summary

• LVCMOS output interface for standard digital logic compatibility
• Integrated standby mode for power management
• Compact 4-SMD no-lead surface mount package

Oscillators Applications

• Digital signal processing circuits
• Microcontroller clock sources
• Communication equipment timing

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the system design specifications before procurement. Ensure the 1.8V supply rail stability meets the oscillator's operational needs. Confirm that the PCB footprint matches the 4-SMD no-lead package dimensions provided in the official datasheet to avoid assembly issues.

Oscillators Selection Notes

Select this component when a 26.1 MHz clock signal is required with LVCMOS outputs. Consider the 1.8V operating voltage and standby feature for power-sensitive designs. Evaluate the thermal performance and size constraints of the 4-SMD package relative to the available board space. Compare alternative frequencies if the exact 26.1 MHz value is not strictly necessary.

Oscillators Part Context

This part belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronics. The series offers various frequencies with consistent LVCMOS outputs and low-voltage operation. The 'PD' suffix typically indicates the presence of a power-down control function. These oscillators are part of Mercury's broader portfolio of frequency control products, including crystals and TCXOs, aimed at providing reliable timing solutions for electronic devices.

Oscillators Replacement Considerations

Direct replacements must match the 26.1 MHz frequency, LVCMOS output type, 1.8V supply voltage, and 4-SMD no-lead package. Verify pinout compatibility and electrical characteristics such as rise/fall times and duty cycle. Consult manufacturer cross-reference lists for equivalent parts from other suppliers offering identical specifications.
