Overview
The 18QHTF21-89.000-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 89 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and includes an enable/disable control feature for power management. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications requiring precise timing signals.
Feature Summary
- LVCMOS output logic for digital interface compatibility
- Integrated enable/disable pin for power control
- Surface-mount 4-SMD no-lead package design
Applications
- General clock signal generation in embedded systems
- Timing reference for digital communication interfaces
- Microcontroller and processor clock sources
Procurement Notes
Verify the specific part number suffix against official Mercury Electronics documentation to confirm voltage and frequency specifications. Ensure the ordering information matches the required LVCMOS output and 1.8V supply parameters. Cross-reference the package type to confirm compatibility with the target PCB footprint.
Selection Notes
Select this component when a stable 89 MHz clock source is required for low-voltage digital circuits. Consider the enable/disable functionality if power efficiency during idle states is a priority. Verify that the LVCMOS output swing meets the input requirements of the receiving logic devices in the design.
Part Context
This model belongs to the 18QHTF21 series of standard crystal oscillators from Mercury Electronics. The series typically offers various frequencies within the same form factor. This specific variant provides the 89 MHz output option, maintaining consistent electrical characteristics and packaging standards across the family.
Replacement Considerations
Direct substitutes must match the 89 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Check manufacturer cross-reference lists for equivalent parts with identical pinouts and electrical specs.
