18QHTF21-26.700-PD

Oscillators Overview

The 18QHTF21-26.700-PD is a crystal oscillator (XO) manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a frequency of 26.7 MHz with an LVCMOS output logic level. The device supports 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. The component is designed for standard clock applications requiring precise timing signals.

Oscillators Feature Summary

• LVCMOS output interface for digital circuit compatibility
• Integrated standby mode to reduce power consumption
• Compact surface-mount package design

Oscillators Applications

• General purpose clock signal generation
• Digital system timing references
• Embedded controller clock sources

Oscillators Procurement Notes

Verify the specific ordering suffix and frequency tolerance against project requirements. Confirm that the 1.8V supply voltage aligns with the target system's power rails. Ensure the 4-SMD no-lead package footprint matches the PCB layout. Check for any specific handling instructions regarding electrostatic discharge sensitivity during assembly.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a standard LVCMOS output. The small 2.0x1.6mm form factor makes it suitable for space-constrained designs. Consider the standby feature if power efficiency is a priority. Verify that the 26.7 MHz frequency meets the system clocking needs without additional dividers.

Oscillators Part Context

This part belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronics. The series offers various frequencies and voltage options within similar physical footprints. The 'PD' suffix typically indicates the presence of a power-down control pin or function. This model specifically targets applications needing a balance between size, power, and standard digital interface compatibility.

Oscillators Replacement Considerations

Direct substitutes must match the 26.7 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Cross-reference with other manufacturers offering equivalent pin-compatible oscillators. Ensure temperature range and load capacitance specifications are compatible with the original design constraints.
