Oscillators Procurement Notes

Verify the exact frequency tolerance and load capacitance requirements against the specific application design before procurement. Ensure the 1.8V supply voltage aligns with the target circuit's power rails. Confirm that the enable/disable pin configuration matches the system's control logic to ensure proper operation during standby modes.

Oscillators Selection Notes

Select this component when a stable 47.4875 MHz clock source is required with low power consumption capabilities. The LVCMOS output is suitable for digital interfaces, while the enable feature allows for dynamic power management. Consider the small form factor for space-constrained designs.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series offers various frequencies with consistent LVCMOS outputs and enable functions. The -OE suffix typically denotes a specific packaging or tape-and-reel configuration, distinct from other suffixes like -PD.

Oscillators Replacement Considerations

Direct replacements must match the 47.4875 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD footprint. Verify electrical compatibility and pinout alignment. Cross-reference with Mercury Electronics' current product listings for updated equivalents.
