18QHTF21-31.000-PD

Oscillators Overview

The 18QHTF21-31.000-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a frequency of 31.0 MHz and utilizes LVCMOS output logic. The device is designed for low-power applications with a supply voltage of 1.8V. It features a Standby (Power Down) function to manage energy consumption. The component is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6mm.

Oscillators Feature Summary

• LVCMOS output interface for digital signal compatibility
• Integrated standby mode for power reduction
• Compact surface-mount form factor

Oscillators Applications

• Low-power clock generation for embedded systems
• Timing reference for portable electronic devices
• Digital circuit synchronization in consumer electronics

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your design specifications before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD no-lead package footprint matches your PCB layout constraints. Check for any RoHS compliance documentation if required by your manufacturing standards.

Oscillators Selection Notes

Select this component when a precise 31.0 MHz timing source is required for 1.8V logic circuits. Consider the LVCMOS output level compatibility with downstream microcontrollers or FPGAs. Evaluate the need for the standby feature if power management is critical. Compare size constraints against larger oscillator packages if space is limited.

Oscillators Part Context

This part belongs to the Mercury Electronic XO series, which provides standard frequency control solutions. The '18' prefix typically indicates the 1.8V supply voltage variant within their product line. The 'PD' suffix denotes the inclusion of a power-down capability. This series is designed for general-purpose timing applications requiring stable frequency generation.

Oscillators Replacement Considerations

Direct replacements must match the 31.0 MHz frequency, 1.8V supply, LVCMOS output, and 2.0x1.6mm package. Verify pinout compatibility if substituting with different manufacturers. Ensure equivalent electrical characteristics such as phase noise and stability are met for the specific application.
