Oscillators Procurement Notes

Verify the specific frequency suffix matches the required system clock. Confirm the package type corresponds to the PCB footprint design. Ensure the supply voltage rating aligns with the target circuit's power domain. Check for any specific operating temperature range requirements before finalizing the order.

Oscillators Selection Notes

Select this model when a 37.93 MHz frequency is strictly required. The 1.8V supply voltage dictates compatibility with low-voltage digital logic families. The small 2.0x1.6mm package is suitable for space-constrained designs. Consider the LVCMOS output swing levels against input thresholds of downstream components.

Oscillators Part Context

This part belongs to the 18QHTF21 series of standard crystal oscillators from Mercury Electronics. The series offers various frequencies within a consistent 4-SMD no-lead package. These components are designed for applications demanding reliable timing sources in compact electronic assemblies.

Oscillators Replacement Considerations

Direct substitutes must match the 37.93 MHz frequency, 1.8V supply, and LVCMOS output. Compatible packages include 4-SMD no-lead variants with identical 2.0x1.6mm dimensions. Verify pinout compatibility and electrical specifications before substitution.
