Oscillators Procurement Notes

Verify the specific ordering suffix matches the required frequency and package variant. Confirm that the 1.8V supply voltage aligns with the target circuit design. Ensure the LVCMOS output level is compatible with the receiving logic inputs. Check for any specific environmental or reliability requirements before finalizing the procurement order.

Oscillators Selection Notes

Select this component when a precise 33.288 MHz reference is required for LVCMOS-compatible circuits. Consider the 1.8V operating voltage constraint during system power budgeting. The power-down feature should be evaluated if system power efficiency is a priority. Verify that the 4-SMD no-lead package fits within the available board space constraints.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series typically offers various frequencies and voltage options. The PD suffix indicates the inclusion of a power-down control pin or function. These components are generally used as primary clock sources in portable and high-density electronic devices.

Oscillators Replacement Considerations

Direct replacements must match the 33.288 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify pinout compatibility and electrical specifications before substitution.
