18QHTF21-59.880-PD

Overview

The 18QHTF21-59.880-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 59.88 MHz with LVCMOS output logic. The device supports a supply voltage of 1.8V and includes a standby or power-down function. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm.

Feature Summary

• LVCMOS output logic for digital interface compatibility
• Integrated standby and power-down control functionality
• Compact 4-SMD no-lead surface mount package

Applications

• General-purpose timing clock generation
• Digital signal processing circuits
• Embedded system microcontroller clocks

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the PCB footprint matches the 2.0x1.6mm SMD package dimensions to prevent assembly errors during manufacturing.

Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a precise 59.88 MHz reference. The LVCMOS output is suitable for direct interfacing with standard digital logic families. Consider the power-down feature if energy efficiency during idle states is a critical design constraint for the application.

Part Context

This part belongs to the Mercury Electronics 18QHTF21 series of surface-mount crystal oscillators. The series offers various frequencies and voltage options within a standardized small form factor. The 'PD' suffix indicates the inclusion of a power-down pin or control feature, distinguishing it from standard continuous-operation variants in the same family.

Replacement Considerations

Direct replacements must match the 59.88 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify pinout compatibility and electrical specifications such as phase noise and jitter before substituting with components from other manufacturers.
