Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target application design before procurement. Ensure the 1.8V supply voltage aligns with the system power rails. Confirm that the LVCMOS output swing is compatible with the receiving logic inputs. Check the datasheet for operating temperature range limitations relative to the intended environment.

Oscillators Selection Notes

Select this component when a precise 28.935 MHz reference is required in a space-constrained design. The 1.8V operation makes it suitable for modern low-power digital systems. Consider the enable pin feature if power management during idle states is necessary. Compare package dimensions against available PCB real estate to ensure mechanical fit.

Oscillators Part Context

This part belongs to the 18QHTF21 series of standard crystal oscillators from Mercury Electronics. The series offers various frequencies within the same physical footprint. The 'OE' suffix typically denotes a specific ordering or packaging variant defined by the manufacturer. These components are commonly used as primary clock sources in consumer electronics and industrial equipment.

Oscillators Replacement Considerations

Direct replacements must match the 28.935 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify electrical parameters such as phase noise and jitter specifications. Ensure thermal characteristics and operating temperature ranges are equivalent or superior to maintain system reliability.
