18QHTF21-100.2083333-PD

Overview

The 18QHTF21-100.2083333-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 100.2083333 MHz and utilizes LVCMOS output logic. 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 2.0mm x 1.6mm.

Feature Summary

• LVCMOS output logic interface
• Integrated standby and power-down functionality
• Compact surface-mount package design

Applications

• Digital signal processing systems
• Communication equipment clocking
• Embedded system timing references

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 host system's power rails. Ensure the 4-SMD no-lead package footprint matches the PCB layout specifications to guarantee proper solder joint integrity and mechanical stability during assembly.

Selection Notes

Select this component when a precise 100.2083333 MHz reference is required for LVCMOS-compatible digital circuits. Consider the low profile and small footprint for space-constrained designs. Evaluate the power-down feature if dynamic power management is critical. Ensure compatibility with the 1.8V operating voltage range and verify thermal performance within the specified operating temperature limits.

Part Context

This part belongs to the Mercury Electronics 18QHTF21 series of standard crystal oscillators. The series offers various frequencies and voltage options in a consistent 2.0x1.6mm SMD package. The 'PD' suffix indicates the inclusion of a power-down control pin, distinguishing it from basic continuous-operation variants within the same form factor family.

Replacement Considerations

Direct replacements must match the 100.2083333 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify equivalent electrical characteristics such as phase noise and jitter specifications. Cross-reference with other manufacturers offering similar low-profile XO solutions with standby capabilities.
