18QHTF21-58.8375-PD

Overview

The 18QHTF21-58.8375-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a frequency of 58.8375 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and includes a standby (power down) function for energy management. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications requiring precise timing signals in electronic circuits.

Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes standby mode to reduce power consumption during idle periods
• Utilizes a leadless SMD package for automated surface-mount assembly

Applications

• Digital signal processing systems requiring clock synchronization
• Communication equipment utilizing standard frequency references
• Embedded control units needing low-power oscillation modes

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the system design specifications before procurement. Confirm that the 1.8V supply voltage aligns with the target circuit's power rails. Ensure the 4-SMD no-lead package footprint matches the PCB layout constraints. Cross-reference the manufacturer datasheet for thermal and electrical limits to guarantee reliable operation under intended operating conditions.

Selection Notes

Select this component when a fixed 58.8375 MHz reference is required with LVCMOS compatibility. Consider the 1.8V operating voltage and standby feature for power-sensitive designs. Evaluate the 4-SMD no-lead package size against available board space. Compare performance metrics such as phase noise and stability if available in official documentation to ensure suitability for the specific application environment.

Part Context

This part belongs to the 18QHTF21 series of standard crystal oscillators from Mercury Electronics. The series offers various frequencies with consistent LVCMOS outputs and 1.8V operation.
