18QHTF21-100.700-PD

Overview

The 18QHTF21-100.700-PD is a crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 100.7 MHz and utilizes LVCMOS output logic. The device requires a 1.8V supply voltage and features a standby or power-down function for energy management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm. This component is designed for applications requiring precise timing signals within a small form factor.

Feature Summary

• Supports LVCMOS output logic for standard digital interfacing
• Includes standby and power-down functionality to reduce power consumption
• Utilizes a compact 4-SMD no-lead surface mount package

Applications

• General clock signal generation in electronic circuits
• Timing reference for digital systems requiring 1.8V operation
• Embedded devices with space-constrained PCB layouts

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your system design before procurement. Confirm that the 1.8V supply voltage aligns with your power architecture. Ensure the 4-SMD no-lead package footprint matches your PCB silkscreen and solder mask definitions. Check for any specific handling instructions regarding electrostatic discharge protection during assembly.

Selection Notes

Select this component when a 100.7 MHz clock source is required with low voltage operation. Consider the LVCMOS output compatibility with your downstream logic levels. Evaluate the physical size constraints to ensure the 2.0x1.6mm package fits within the designated area. Assess the need for power-down capabilities if battery life or thermal management is a priority in the application.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies in a standardized small outline package. The series typically provides standard XO performance with integrated power management features. The 'PD' suffix indicates the inclusion of power-down control functionality. These oscillators are commonly used in portable electronics and communication modules where size and power efficiency are critical factors.

Replacement Considerations

Direct substitutes must match the 100.7 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package dimensions. Verify pinout compatibility and electrical characteristics such as phase noise and jitter specifications. Consult manufacturer cross-reference lists for equivalent parts from other suppliers offering similar form factors and performance metrics.
