18QHTF21-47.6667-PD

Oscillators Overview

The 18QHTF21-47.6667-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a fixed frequency of 47.6667 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and includes a standby or power-down function to manage energy consumption. It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount applications requiring precise timing signals.

Oscillators Feature Summary

• Supports low-voltage operation with 1.8V supply requirement
• Integrates standby mode for power management
• Provides LVCMOS output signal compatibility

Oscillators Applications

• Embedded systems requiring stable clock references
• Consumer electronics with space constraints
• Industrial control modules needing precise timing

Oscillators Procurement Notes

Verify the specific suffix 'PD' confirms the power-down capability and 1.8V specification during procurement. Ensure the 4-SMD no-lead footprint matches the target PCB design. Confirm that the 47.6667 MHz frequency aligns with system requirements. Cross-reference the manufacturer's latest datasheet for any updates on pinout or electrical characteristics before finalizing orders.

Oscillators Selection Notes

Select this component when a low-profile, surface-mount oscillator is required for 1.8V logic interfaces. The LVCMOS output ensures direct compatibility with standard digital inputs without additional buffering. Consider the standby feature if power efficiency is critical. Verify that the 47.6667 MHz frequency is strictly necessary, as other frequencies in the series may be available.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies in a small SMD package. The series typically supports LVCMOS outputs and low-voltage operation. The 'PD' suffix likely denotes specific power-down functionality distinct from other variants like 'OE'. This family targets applications demanding reliability and compact form factors.

Oscillators Replacement Considerations

Direct substitutes must match the 47.6667 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Verify pin compatibility and thermal characteristics. Other Mercury Electronics parts in the 18QHTF21 series with different suffixes may offer similar footprints but different electrical features.
