18QHTF21-30.370-PD

Oscillators Overview

The 18QHTF21-30.370-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 30.37 MHz and utilizes LVCMOS output logic. The device is designed for low-voltage applications, requiring a supply voltage of 1.8V. A key functional characteristic is the inclusion of a standby or power-down mode to manage energy consumption during inactive periods. The component is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm, suitable for space-constrained surface-mount designs.

Oscillators Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Features a standby or power-down mode for energy efficiency
• Utilizes a compact 4-SMD No Lead surface-mount package

Oscillators Applications

• General clock signal generation in embedded systems
• Timing reference for low-voltage digital circuits
• Portable electronic devices requiring power management

Oscillators Procurement Notes

Verify the specific operating temperature range and load capacitance requirements against the target application's design specifications before procurement. Ensure that the PCB footprint matches the 2.0 x 1.6 mm SMD package dimensions. Confirm that the 1.8V supply rail is stable and within the operational limits defined in the official datasheet to guarantee reliable oscillator performance and frequency stability.

Oscillators Selection Notes

Select this component when a precise 30.37 MHz timing source is required for LVCMOS-compatible logic families. The choice is driven by the need for a low-profile surface-mount solution with integrated power-down capabilities. Consider the 1.8V supply constraint and the specific frequency requirement as primary selection criteria over generic oscillator alternatives.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which focuses on small-form-factor oscillators. The series typically offers various frequency options within a standardized 4-SMD package. The 'PD' suffix indicates the presence of a power-down control feature, distinguishing it from continuous-operation variants within the same physical footprint family.

Oscillators Replacement Considerations

Direct substitutes must match the 30.37 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify pinout compatibility and thermal characteristics. Cross-reference with other manufacturers offering similar low-profile XO components with standby functionality.
