Overview
The 18QHTF21-115.330-OE is a crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 115.33 MHz with an LVCMOS output logic level. The device requires a supply voltage of 1.8V and features an Enable/Disable control function. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm.
Feature Summary
- Supports Enable/Disable functionality for power management
- Utilizes LVCMOS output logic for digital interface compatibility
- Designed in a small surface-mount package for space-constrained applications
Applications
- General clock signal generation in electronic circuits
- Data communication systems requiring precise timing
- Embedded systems utilizing low-voltage logic interfaces
Procurement Notes
Verify the specific suffix 'OE' corresponds to the Enable/Disable feature when sourcing replacements. Confirm that the 1.8V supply requirement matches the target circuit design. Ensure the 4-SMD No Lead package footprint aligns with the PCB layout specifications before finalizing procurement.
Selection Notes
Select this component where a 115.33 MHz clock source is required within a 2.0x1.6 mm footprint. The 1.8V operating voltage makes it suitable for modern low-power digital designs. The Enable/Disable pin allows for dynamic power control, which is beneficial for battery-operated or energy-efficient system architectures.
Part Context
This model belongs to the Mercury Electronics SMD Oscillator series, specifically designed for high-frequency applications. The '18QHTF21' prefix indicates the series characteristics, while the numeric suffix defines the exact frequency. The manufacturer specializes in quartz-based frequency control products, including crystals and oscillators.
Replacement Considerations
The datasheet lists the 18QHTF21-115.330-PD as a variant with Power Down functionality instead of Enable/Disable. Both share the same frequency, voltage, and package dimensions. Verify if the specific control logic (OE vs PD) is compatible with the existing design before substitution.
