Oscillators Procurement Notes

Verify the specific suffix 'OE' against the manufacturer's current datasheet to confirm availability and exact electrical tolerances. Ensure the 1.8V supply requirement matches the target circuit design. Confirm that the 4-SMD no-lead package footprint aligns with the PCB layout specifications before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a 21.0961 MHz clock source is required with low voltage operation. The enable/disable feature makes it suitable for battery-powered devices where power conservation is critical. Consider the small 2.0x1.6mm footprint for high-density board layouts. Verify temperature range requirements against the application environment.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies within the same physical package. The series provides standardized LVCMOS outputs for computing and communication applications. The 'O' suffix typically denotes a specific tape and reel packaging option, while 'E' may indicate environmental compliance or specific testing criteria as defined by the manufacturer.

Oscillators Replacement Considerations

Direct replacements must match the 21.0961 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Check equivalent parts from other manufacturers ensuring identical pinout and control logic. Verify that substitute components meet the same operating temperature and stability specifications.
