18QHTF21-88.360-PD

Overview

The 18QHTF21-88.360-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 88.36 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and includes a standby or power-down feature for energy management. It is housed in a compact 4-SMD, no-lead package with dimensions of 2.0x1.6 mm. This component is designed for applications requiring precise timing signals within low-voltage digital systems.

Feature Summary

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

Applications

• Digital signal processing circuits
• Communication equipment timing references
• Embedded system clock generation

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Ensure that the 1.8V supply voltage aligns with your system's power rails. Confirm that the 4-SMD no-lead package footprint matches your PCB layout constraints. Check for any specific operating temperature range limitations defined in the official datasheet for your application environment.

Selection Notes

Select this model when a precise 88.36 MHz reference is required in space-constrained designs. The LVCMOS interface ensures compatibility with standard logic families. Consider the standby feature if power efficiency is critical. Verify that the 1.8V operation suits your voltage domain. The small form factor makes it suitable for high-density board layouts where larger packages are not feasible.

Part Context

This oscillator belongs to the Mercury Electronics 18QHTF21 series, which provides various frequency options in a standardized 2.0x1.6 mm package. The series supports LVCMOS outputs and 1.8V operation, catering to modern low-power digital applications. The 'PD' suffix indicates the inclusion of a power-down capability, distinguishing it from non-stby variants within the same physical footprint family.

Replacement Considerations

Direct replacements must match the 88.36 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Verify pinout compatibility and electrical characteristics such as phase noise and jitter specifications. Ensure the substitute part also supports the standby function if required by the design.
