Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 2.5V supply voltage aligns with your system's power rails. Ensure the 4-SMD no-lead package dimensions fit within your PCB footprint constraints. Cross-reference the manufacturer datasheet for absolute maximum ratings to prevent operational damage during integration.

Oscillators Selection Notes

Select this component when a stable 36.6666 MHz reference is required with low-power standby capabilities via the enable pin. Consider the LVCMOS compatibility with downstream digital inputs. Evaluate thermal performance and aging characteristics if long-term stability is critical. Compare against alternative frequencies if the exact 36.6666 MHz value is not strictly mandated by the application protocol.

Oscillators Part Context

This part belongs to the 25QHTF21 series from Mercury Electronic, a manufacturer specializing in quartz crystals and oscillators since 1973. The series typically includes various frequencies such as 25.66875 MHz, 49.680 MHz, and 13.5168 MHz, all sharing similar package and electrical characteristics like 2.5V operation and LVCMOS outputs.

Oscillators Replacement Considerations

Direct substitutes include other 25QHTF21 variants with different frequencies if the clock source is programmable or flexible. For identical frequency replacement, verify equivalent specifications from Mercury Electronic or authorized distributors. Ensure any cross-brand replacement matches the LVCMOS output swing and package outline drawing.
