18QHTF21-90.088-OE

Overview

The 18QHTF21-90.088-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a fixed frequency of 90.088 MHz and utilizes LVCMOS output logic levels. The device is designed for low-voltage applications, functioning at a supply voltage of 1.8V. It features an enable/disable control pin for power management flexibility. The component is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm, suitable for surface-mount assembly on printed circuit boards.

Feature Summary

• Compact 4-SMD no-lead package design for space-constrained applications
• Low voltage operation at 1.8V supply
• LVCMOS output interface compatibility
• Enable/Disable functionality for power control

Applications

• Clock signal generation in digital communication systems
• Timing reference for high-speed data processing circuits
• Embedded system clock sources requiring low voltage operation

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to ensure correct package type and electrical characteristics. Confirm that the OE variant matches the required enable/disable functionality and LVCMOS output levels. Cross-reference the frequency tolerance and load capacitance requirements with the target circuit design specifications before procurement.

Selection Notes

Select this component when a precise 90.088 MHz timing source is required within a low-power 1.8V environment. The small 2.0x1.6 mm footprint makes it suitable for dense PCB layouts. Ensure the application supports LVCMOS logic levels and requires an active enable control signal for power optimization during idle states.

Part Context

This part belongs to the Mercury Electronics 18QHT series of surface-mount crystal oscillators. The series is characterized by its small form factor and low voltage operation capabilities. Mercury Electronics is a specialized manufacturer of frequency control products, including quartz crystals and oscillators, with a focus on providing reliable timing solutions for electronic devices.

Replacement Considerations

Direct substitutes include the 18QHTF21-90.088-PD variant from the same manufacturer, which shares identical electrical specifications but may differ in packaging strip configuration. Verify pinout compatibility and mechanical dimensions before swapping components in existing designs.
