18QHTF21-59.28333-PD

Overview

The 18QHTF21-59.28333-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a frequency of 59.28333 MHz with an LVCMOS output logic level. The device is powered by a 1.8V supply voltage and features a Standby (Power Down) function for energy management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm.

Feature Summary

• Supports Standby mode for power down functionality
• Utilizes LVCMOS output logic interface
• Compact 4-SMD No Lead surface mount package

Applications

• General purpose clock signal generation
• Embedded system timing references
• Digital circuit synchronization

Procurement Notes

Verify the specific ordering suffix to ensure the correct pinout and electrical characteristics match the design requirements. Confirm that the 1.8V supply voltage aligns with the target system's power rails. Ensure the 4-SMD No Lead package footprint is compatible with the PCB layout and manufacturing capabilities before finalizing the procurement order.

Selection Notes

Select this component when a precise 59.28333 MHz clock source is required with low power consumption capabilities. The choice is driven by the need for a small form factor suitable for dense PCB layouts. Consider the LVCMOS compatibility with downstream digital logic levels and the necessity of a standby feature for battery-operated or power-sensitive applications.

Part Context

This part belongs to the QHTF series of crystal oscillators from Mercury Electronic Ind. Co., Ltd. The series is characterized by its small size and low power consumption, making it suitable for portable electronics. Mercury Electronics has a long history in quartz crystal manufacturing, providing reliable frequency control solutions.

Replacement Considerations

Direct substitutes may include other models within the same Mercury QHTF series with identical frequency and package but different suffixes indicating variations in tolerance or temperature range. Cross-referencing with other manufacturers requires matching the 4-SMD No Lead footprint, 1.8V supply, and LVCMOS output type.
