Procurement Notes
Verify the specific ordering suffix against the manufacturer's current documentation to ensure correct frequency and package specifications. Confirm that the required operating temperature range aligns with the application environment. Check for any recent updates to the datasheet regarding electrical characteristics or mechanical dimensions before finalizing procurement.
Selection Notes
Select this component when a low-profile oscillator with enable control is required for 101.5 MHz applications. Ensure the design accommodates the 1.6mm x 1.2mm footprint. Consider the LVCMOS output swing requirements relative to the receiving circuit's input thresholds. Verify supply voltage compatibility with the system's 1.8V or 3.3V rails.
Part Context
This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series offers various frequencies and supply voltages in a standardized small outline package. It is designed for general-purpose timing applications where size and power efficiency are critical factors.
Replacement Considerations
Direct replacements must match the 101.5 MHz frequency, LVCMOS output, and 4-SMD no-lead package. Verify pinout compatibility and electrical parameters such as load capacitance and drive level. Cross-reference with other manufacturers offering similar form-factor oscillators if availability is an issue.
