Oscillators Procurement Notes

Verify the specific frequency suffix matches the required 36.12676 MHz specification. Confirm the 1.8V supply voltage requirement aligns with the target circuit design. Ensure the 4-SMD no-lead package footprint corresponds to the PCB layout constraints. Check for any specific RoHS or environmental compliance documentation if required by the manufacturing process.

Oscillators Selection Notes

Select this component when a precise 36.12676 MHz clock source is needed with minimal power usage. The LVCMOS output is suitable for digital logic interfaces operating at 1.8V. Consider the small form factor for space-constrained designs. Evaluate the standby feature if power management during idle states is critical for the application.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various standard frequencies in a 2.0x1.6mm package. The series typically supports 1.8V operation and includes power-down capabilities. Other variants in this family differ primarily in their output frequency specifications while maintaining similar electrical and physical characteristics.

Oscillators Replacement Considerations

Direct substitutes must match the 36.12676 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Verify that alternative manufacturers provide equivalent phase noise and stability specifications. Ensure the replacement part supports the same standby functionality.
