18QHTF21-30.030-PD

Oscillators Overview

The 18QHTF21-30.030-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 30.03 MHz and utilizes LVCMOS output logic. The device is designed for low-power applications, featuring a 1.8V supply voltage with an integrated standby or power-down function to minimize energy consumption during idle states. It is housed in a compact 4-SMD, no-lead package, suitable for surface-mount assembly on printed circuit boards.

Oscillators Feature Summary

• Integrates LVCMOS output interface for digital signal compatibility
• Supports standby mode for reduced power consumption
• Utilizes surface-mount no-lead packaging for automated assembly

Oscillators Applications

• General-purpose clock generation in embedded systems
• Timing reference for microcontrollers requiring 30.03 MHz input
• Low-power consumer electronics devices

Oscillators Procurement Notes

Verify the specific operating temperature range and load capacitance requirements against the official datasheet before integration. Confirm that the 1.8V supply rail stability meets the oscillator's jitter specifications. Ensure the PCB layout adheres to the manufacturer's recommended footprint dimensions for the 4-SMD package to maintain signal integrity and thermal performance.

Oscillators Selection Notes

Select this component when a precise 30.03 MHz timing source is required with minimal power draw. The LVCMOS output is suitable for direct interfacing with standard digital logic families. Consider the 1.8V operation if the system design prioritizes low-voltage efficiency over higher drive strength capabilities found in other voltage variants.

Oscillators Part Context

This part belongs to the Mercury Electronics XO series, which provides stable frequency references for various electronic circuits. The 'PD' suffix typically indicates the inclusion of a power-down control feature, allowing the oscillator to be disabled when not in use. This series is designed for applications requiring reliable timing in space-constrained environments.

Oscillators Replacement Considerations

Direct substitutes must match the 30.03 MHz frequency, LVCMOS output type, 1.8V supply voltage, and 4-SMD no-lead package dimensions. Verify pinout compatibility and electrical characteristics such as phase noise and duty cycle before swapping manufacturers.
