18QHTF21-26.660-PD

Oscillators Overview

The 18QHTF21-26.660-PD is a 26.66 MHz crystal oscillator manufactured by Mercury Electronics Ind. Co., Ltd. It operates on a 1.8V supply voltage and utilizes LVCMOS output logic. The device features a Standby function for power management, allowing the unit to enter a Power Down state when not in active use. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6mm. This component is designed for applications requiring precise timing signals within low-voltage digital systems.

Oscillators Feature Summary

• Supports LVCMOS output logic for standard digital interfacing
• Includes Standby mode capability for power reduction
• Compact surface-mount package design

Oscillators Applications

• Battery-powered portable devices
• Low-voltage digital circuits
• Timing signal generation in embedded systems

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your system design before ordering. Confirm that the 1.8V supply voltage aligns with your target platform's power rails. Ensure the 4-SMD no-lead package footprint matches your PCB layout constraints. Check for any RoHS compliance documentation if required by your manufacturing standards.

Oscillators Selection Notes

Select this component when a 26.66 MHz clock source is required for 1.8V logic families. Consider the standby feature if power efficiency is critical for the application. Evaluate the small form factor suitability for dense PCB layouts. Compare against other frequencies in the 18QHTF21 series if different clock speeds are needed.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series offers various standard frequencies with consistent 1.8V operation and LVCMOS outputs. The 'PD' suffix typically indicates the inclusion of a power-down or standby control pin/functionality across the product line.

Oscillators Replacement Considerations

Direct substitutes may include other 26.66 MHz XO units with identical 1.8V LVCMOS specifications and compatible 2.0x1.6mm footprints. Verify electrical compatibility and pinout alignment before swapping manufacturers.
