Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply voltage aligns with the system's power rails. Ensure the PCB footprint matches the 4-SMD no-lead package dimensions to prevent assembly errors during manufacturing.

Oscillators Selection Notes

Select this component when a precise 48.6 MHz clock signal is required for LVCMOS-compatible circuits. The choice is driven by the need for low power consumption in portable applications and the requirement for a small form factor. Consider the operating temperature range and stability needs relative to the environment where the device will be deployed.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series offers various frequencies and supply voltages, including 51.2 MHz and 68.665 MHz variants. The 'PD' suffix indicates the inclusion of a power-down pin for active management of energy usage.

Oscillators Replacement Considerations

Direct substitutes include other 48.6 MHz LVCMOS oscillators in 2.0x1.6mm packages. Compatible alternatives may include parts from manufacturers such as Epson or SiTime, provided they match the electrical specifications and pinout configuration.
