Oscillators Procurement Notes

Verify the specific manufacturer designation, as sources reference both Aker Technology Corp and Aker Technology USA. Confirm that the ordering suffix '-R' corresponds to the required tape and reel packaging configuration. Ensure compatibility with 1.8V logic levels before integration into the target circuit design.

Oscillators Selection Notes

Select this component when a 27 MHz frequency is required alongside active enable/disable control capabilities. The 4-SMD no-lead package offers a small footprint for dense layouts. Verify that the HCMOS output swing matches the input requirements of the receiving clock pin on the host device.

Oscillators Part Context

This model belongs to the S21805T series of surface-mount crystal oscillators from Aker Technology. The series provides various frequency options within a standardized package form factor. The '27.000' designation indicates the specific operating frequency of 27 megahertz for this particular variant.

Oscillators Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-reference with other 27 MHz HCMOS oscillators in the 4-SMD no-lead package only if electrical parameters and pinout configurations are verified to be identical.
