Procurement Notes
Verify the specific suffix (OE) against official datasheets to confirm enable/disable capabilities and electrical characteristics. Ensure compatibility with 1.8V supply rails and LVCMOS logic thresholds before integration. Cross-reference part numbers with manufacturer documentation to avoid confusion with similar models lacking control features.
Selection Notes
Select this component when a low-voltage 1.8V oscillator with active control is required. The LVCMOS output ensures compatibility with standard digital logic families. Consider the 4-SMD footprint for space-constrained designs. Verify frequency accuracy requirements align with the standard specification provided by the manufacturer.
Part Context
This model belongs to the 18QHTF21 series from Mercury Electronics, which specializes in frequency control products. The series typically offers various frequencies within a small form factor. Mercury Electronics has been a pioneer in the crystal industry since 1973, providing reliable timing solutions for global markets.
Replacement Considerations
Check for direct substitutes like 18QHTF21-56.448-PD if available, ensuring identical pinout and electrical specs. Verify that alternative parts support the same 1.8V supply and LVCMOS output type. Confirm package dimensions match the 4-SMD no lead configuration to maintain board layout integrity.
