Overview
The 18QHTF21-8.500-OE is a crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a nominal frequency of 8.5 MHz with an LVCMOS output logic level. The device requires a supply voltage of 1.8V and features enable/disable functionality for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm. The component supports an operating temperature range of -40°C to 85°C and offers a frequency stability of ±50ppm.
Feature Summary
- Compact 4-SMD surface-mount package design
- Integrated enable and disable control function
- LVCMOS output signal compatibility
Applications
- Embedded system clock generation
- Consumer electronics timing circuits
- Industrial control module synchronization
Procurement Notes
Verify the specific suffix 'OE' against the manufacturer's official datasheet to confirm pinout and electrical characteristics match your design requirements. Ensure the 1.8V supply rail is stable within the specified tolerance. Confirm that the 2.0x1.6mm footprint aligns with your PCB layout constraints. Cross-reference the ±50ppm stability requirement with your system's timing budget before finalizing procurement.
Selection Notes
Select this component when a low-profile 2.0x1.6mm oscillator is required for space-constrained designs. The 1.8V supply voltage makes it suitable for modern low-power digital logic families. Consider the ±50ppm stability specification against your application's jitter tolerance. The enable/disable feature allows for dynamic power saving in battery-operated devices compared to always-on alternatives.
Part Context
This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series typically includes various frequencies and voltage options, such as 3.3V variants or different package sizes like 3.2x2.5mm. The 'OE' suffix likely denotes a specific output configuration or packaging variant within this product line, distinguishing it from other models like the PD version.
Replacement Considerations
Direct substitutes include the 18QHTF21-8.502-PD, which shares the same frequency and package but may differ in output type or suffix specifications. Verify if the PD variant meets the LVCMOS requirement. Other frequencies in the 18QHTF21 series are not electrically compatible without circuit redesign.
