18QHTF21-67.100-PD

Overview

The 18QHTF21-67.100-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 67 MHz and utilizes LVCMOS output logic. The component requires a 1.8V supply voltage 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 2.0x1.6mm.

Feature Summary

• Supports standby mode for power reduction
• Utilizes LVCMOS output interface
• Compact surface-mount form factor

Applications

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

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target design specifications before procurement. Confirm that the 1.8V operating voltage aligns with the system power rails. Ensure the 4-SMD no-lead package footprint matches the PCB layout to prevent assembly issues during manufacturing.

Selection Notes

Select this component when a low-voltage 67 MHz clock source is required for space-constrained designs. Consider the LVCMOS compatibility with downstream digital inputs. Evaluate the thermal performance and stability needs relative to the specified operating temperature range for the intended application environment.

Part Context

This part belongs to the Mercury Electronics XO series, designed for standard clock applications. It represents a solution for integrating precise timing signals into modern electronic devices requiring small footprints and low power consumption. The product line emphasizes reliability in frequency control for consumer and industrial electronics.

Replacement Considerations

Direct substitutes must match the 67 MHz frequency, 1.8V supply, LVCMOS output, and 2.0x1.6mm package dimensions. Verify pinout compatibility and electrical characteristics such as phase noise and jitter specifications to ensure functional equivalence in the existing circuit design.
