18QHTF21-58.74875-PD

Overview

The 18QHTF21-58.74875-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 58.74875 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and features a standby power-down mode for energy efficiency. It is housed in a compact 4-SMD, no-lead package suitable for surface-mount applications.

Feature Summary

• LVCMOS output logic interface
• Standby power-down mode support
• Compact 4-SMD no-lead package

Applications

• General clock signal generation
• Digital circuit timing reference
• Embedded system clock sources

Procurement Notes

Verify the specific ordering suffix to ensure the correct package type and electrical characteristics match the design requirements. Confirm that the 1.8V supply voltage aligns with the target system's power rails. Check for any specific tape and reel packaging requirements if automated assembly is planned. Ensure the operating temperature range meets the environmental conditions of the final application.

Selection Notes

Select this component when a precise 58.74875 MHz clock source is required with low power consumption capabilities. The LVCMOS output is compatible with standard digital logic families. Consider the 4-SMD footprint for space-constrained designs. Verify that the standby feature is necessary for power management strategies in the target application.

Part Context

This part belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronics. The series offers various frequencies and output types. The -PD suffix typically indicates a specific package or operational mode variant within the product line. Mercury Electronics has been a manufacturer of frequency control products since 1973.

Replacement Considerations

Direct substitutes may include other 18QHTF21 series variants with the same frequency but different packages or logic levels. Cross-reference with other manufacturers offering 4-SMD LVCMOS oscillators at 58.74875 MHz. Ensure pinout compatibility and electrical specifications match before substitution.
