18QHTF21-101.2656-PD

Overview

The 18QHTF21-101.2656-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 101.2656 MHz and utilizes LVCMOS output logic levels. The device is designed for low-voltage applications, requiring a supply voltage of 1.8V. A key functional characteristic is the inclusion of a standby or power-down mode capability, allowing for energy management during inactive periods. The component is housed in a compact 4-SMD, No Lead package, suitable for surface-mount assembly processes.

Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Features integrated standby or power-down functionality
• Operates on a 1.8V supply voltage rail

Applications

• Digital signal processing systems
• Communication equipment requiring precise clocking
• Embedded control circuits

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to ensure correct frequency and package configuration. Confirm that the LVCMOS output type matches system requirements. Check for RoHS compliance status if environmental regulations apply. Ensure the 1.8V supply voltage aligns with the target circuit design before procurement.

Selection Notes

Select this component when a 101.2656 MHz clock source is required with LVCMOS outputs. Consider the 1.8V operating voltage for compatibility with low-power logic families. Evaluate the 4-SMD no-lead package dimensions for PCB space constraints. Verify that the standby feature meets power management needs.

Part Context

This part belongs to the Mercury Electronics 18QHTF21 series of standard crystal oscillators. The series offers various frequencies with LVCMOS outputs and 1.8V operation. The 'PD' suffix typically indicates a specific package or tape-and-reel configuration, though exact details require datasheet verification. Mercury Electronics specializes in quartz-based frequency control products.

Replacement Considerations

Direct substitutes must match the 101.2656 MHz frequency, LVCMOS output, 1.8V supply, and 4-SMD no-lead package. Verify pinout compatibility and electrical specifications. Cross-reference with other Mercury Electronics models in the same series for potential equivalents.
