Oscillators Procurement Notes

Verify the specific suffix '-OE' against the manufacturer's official documentation to confirm that it denotes the correct enable/disable functionality and packaging variant. Ensure the required operating temperature range aligns with the datasheet specifications before procurement. Cross-reference the part number with authorized distributors to confirm authenticity and availability status.

Oscillators Selection Notes

Select this oscillator when a 22.5791 MHz clock source is required with low voltage operation. Consider the 1.8V supply requirement and LVCMOS output levels for compatibility with downstream logic. Evaluate the 2.0x1.6mm footprint constraints against the PCB layout requirements. Confirm that the enable/disable feature meets the system's power efficiency goals.

Oscillators Part Context

This component belongs to the 18QHTF21 series of standard crystal oscillators from Mercury Electronics. The series typically offers various frequencies and package sizes. The '18QHTF21' prefix indicates the specific family characteristics, while the numerical suffix defines the frequency. The '-OE' suffix likely specifies the enable function and package type as documented in the product listing.

Oscillators Replacement Considerations

Direct substitutes must match the 22.5791 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package dimensions. Verify electrical parameters such as load capacitance and drive level if available in the original datasheet. Generic replacements may require verification of pinout compatibility and thermal performance.
