18QHTF21-47.250-PD

Oscillators Overview

The 18QHTF21-47.250-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 47.25 MHz and utilizes an LVCMOS output signal format. 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 with dimensions of 2.0x1.6 mm, designed for surface-mount applications.

Oscillators Feature Summary

• Generates a precise 47.25 MHz clock signal using LVCMOS logic levels
• Integrates a standby mode to reduce power consumption during inactive periods
• Utilizes a miniature 4-SMD no-lead footprint suitable for space-constrained designs

Oscillators Applications

• Digital signal processing systems requiring stable clock sources
• Communication equipment utilizing LVCMOS interfaces
• Portable electronic devices necessitating low-power operation

Oscillators Procurement Notes

Verify the specific ordering suffix against official Mercury Electronics documentation to confirm pinout compatibility and electrical tolerances. Ensure the procurement channel provides original manufacturer certification to guarantee authenticity. Cross-reference the package outline drawing with the PCB footprint design to prevent mechanical assembly errors during production.

Oscillators Selection Notes

Select this component when a 47.25 MHz frequency is strictly required alongside LVCMOS output compatibility. Evaluate the 1.8V supply constraint against the system's power rails. Consider the 2.0x1.6 mm package size relative to available board real estate. Confirm that the standby feature aligns with the application's power management strategy.

Oscillators Part Context

This model belongs to the Mercury Electronics XO series, which focuses on standard frequency control solutions. The manufacturer specializes in quartz-based components, including crystals and oscillators, leveraging decades of experience in Taiwan's electronics sector. This specific part represents a compact, low-voltage solution within their broader portfolio of timing devices.

Oscillators Replacement Considerations

Direct substitutes must match the 47.25 MHz frequency, LVCMOS output type, 1.8V supply, and 4-SMD 2.0x1.6mm package. Verify pin configuration and electrical characteristics before integration. No alternative part numbers are explicitly confirmed in public documentation.
