18QHTF21-11.2986-PD

Overview

The 18QHTF21-11.2986-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a frequency of 11.2986 MHz and utilizes LVCMOS output logic. 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 2.0 x 1.6 mm.

Feature Summary

• Supports low-voltage operation at 1.8V
• Integrates standby mode for power reduction
• Utilizes LVCMOS output interface

Applications

• Embedded system clock generation
• Portable electronic devices requiring low power consumption
• Communication modules utilizing standard frequency references

Procurement Notes

Verify the specific operating temperature range and load capacitance requirements against the target application environment before procurement. Ensure that the 1.8V supply rail stability meets the oscillator's jitter specifications. Confirm that the PCB layout accommodates the 2.0x1.6mm footprint and no-lead soldering process to guarantee reliable electrical contact and thermal performance during assembly.

Selection Notes

Select this component when a precise 11.2986 MHz reference is required for LVCMOS-compatible digital circuits. Consider the 1.8V supply constraint and the necessity for a power-down feature to manage battery life in portable applications. Evaluate the small form factor suitability for high-density board designs where space is limited compared to larger oscillator packages.

Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series offers various frequency options within a standardized 2.0x1.6mm package. The 'PD' suffix indicates the inclusion of a power-down control pin, distinguishing it from continuous-operation variants within the same physical footprint family.

Replacement Considerations

Direct substitutes must match the 11.2986 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Verify pin compatibility and thermal characteristics. Cross-reference with other manufacturers offering identical footprint and electrical parameters to ensure seamless integration without redesign.
