The component supports 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 2.0x1.6mm.
Feature Summary
- Supports active low enable/disable functionality for power management
- Utilizes LVCMOS output logic for digital interface compatibility
- Compact 4-SMD no-lead surface mount package design
Applications
- General clock signal generation in electronic circuits
- Data communication systems requiring precise timing
- Embedded systems utilizing LVCMOS interfaces
Procurement Notes
Verify the exact frequency specification against the official datasheet to ensure it matches the required 86.863 MHz application. Confirm that the 1.8V supply voltage aligns with the target system's power rails. Ensure the 4-SMD package footprint is compatible with the PCB layout. Check for any specific operating temperature range requirements defined in the manufacturer documentation before finalizing the order.
Selection Notes
Select this component when a low-profile 2.0x1.6mm oscillator is required for LVCMOS applications. The 1.8V supply voltage makes it suitable for modern low-power digital designs. The enable/disable feature allows for dynamic power control. Verify that the standard XO performance meets the jitter and stability requirements of the specific circuit design without needing additional filtering.
Part Context
This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series typically offers various frequencies within a small form factor. The suffix -OE indicates the inclusion of an output enable pin. This model is distinct from other variants in the series that may differ in frequency, voltage, or package size.
Replacement Considerations
Direct substitutes must match the 86.863 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify pinout compatibility, specifically the enable pin configuration. Cross-reference with other manufacturers offering similar SMD oscillators if availability is an issue.
