Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Ensure the 1.8V supply voltage aligns with your system's power rails. Confirm that the 4-SMD package dimensions fit within your PCB layout constraints. Check for any specific handling instructions regarding ESD sensitivity during assembly.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside LVCMOS compatibility. The integrated standby feature makes it suitable for battery-powered or power-sensitive applications. Consider the 4-SMD form factor for space-constrained designs. Verify that the 48.2133 MHz frequency meets the exact timing needs of the target application without requiring external dividers.

Oscillators Part Context

This part belongs to the 18QHTF21 series of standard oscillators from Mercury Electronics. The series typically offers various frequencies and voltage options. The 'PD' suffix likely indicates a specific packaging or tape-and-reel configuration, though official datasheet confirmation is required. This model represents a specific frequency variant within the broader product line.

Oscillators Replacement Considerations

Direct replacements must match the 1.8V supply, LVCMOS output, 48.2133 MHz frequency, and 4-SMD package. Other manufacturers offering similar specifications should be evaluated for pin compatibility and electrical performance equivalence. Verify that any substitute maintains the same standby functionality and operating temperature range.
