18QHTF21-30.300-PD

Oscillators Overview

The 18QHTF21-30.300-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 30.3 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, designed for surface-mount applications requiring precise timing signals.

Oscillators Feature Summary

• LVCMOS output logic interface
• Integrated standby and power-down functionality
• Surface-mount 4-SMD no lead package

Oscillators Applications

• Digital signal processing circuits
• Communication equipment timing
• Microcontroller clock sources

Oscillators Procurement Notes

Verify the specific operating temperature range and load capacitance requirements against the target application design before procurement. Confirm that the 1.8V supply voltage aligns with the system power architecture. Ensure the 4-SMD no lead footprint matches the PCB layout specifications to guarantee proper soldering and mechanical stability during assembly.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a standard LVCMOS interface. The inclusion of a power-down feature makes it suitable for battery-operated devices where standby current reduction is critical. The small form factor is ideal for space-constrained designs needing a reliable 30.3 MHz reference signal without complex external tuning.

Oscillators Part Context

This part belongs to the Mercury Electronics XO series, which provides quartz-based timing solutions. Mercury Electronic Ind. Co. Ltd has a history of manufacturing frequency control products since 1973, specializing in crystals, oscillators, and filters. This specific model represents their standard oscillator line offering precise frequency stability in a compact surface-mount package.

Oscillators Replacement Considerations

Direct substitutes must match the 30.3 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no lead package dimensions. Verify pin compatibility and thermal characteristics if replacing with components from other manufacturers within the same frequency control category.
