18QHTF21-27.130-PD

Oscillators Overview

The 18QHTF21-27.130-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 27.13 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features a standby or power-down function to manage energy consumption. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm. This component serves as a precise clock source for digital circuits requiring low-profile surface-mount integration.

Oscillators Feature Summary

• Supports standby mode for power management
• Utilizes LVCMOS output interface
• Compact 4-SMD no-lead package design

Oscillators Applications

• Digital clock signal generation
• Low-power embedded systems
• Consumer electronics timing references

Oscillators Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required frequency tolerance and load capacitance specifications. 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 constraints. Check for any industry-specific certifications required for the final assembly process.

Oscillators Selection Notes

Choose this model when a small form factor is critical for space-constrained designs. The LVCMOS output is suitable for direct interfacing with standard digital logic families. Consider the 1.8V operating voltage if the system architecture relies on low-voltage power domains. Evaluate the standby feature if power efficiency during idle states is a primary design requirement.

Oscillators Part Context

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

Oscillators Replacement Considerations

Direct substitutes must match the 27.13 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Verify pinout compatibility and thermal characteristics before substitution.
