Oscillators Procurement Notes

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

Oscillators Selection Notes

Select this component when a 48.1 MHz clock source is required with LVCMOS compatibility. Consider the 1.8V operating voltage constraint and the need for active enable/disable control. The small SMD footprint makes it suitable for high-density PCB layouts where space is limited compared to larger oscillator packages.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronic, which offers various frequencies within a standardized 2016 SMD form factor. The series typically supports LVCMOS outputs and includes enable/disable features across different voltage options. It serves as a timing solution for consumer electronics and industrial control systems requiring reliable clock signals.

Oscillators Replacement Considerations

Direct replacements must match the 48.1 MHz frequency, LVCMOS output type, 1.8V supply voltage, and 4-SMD no-lead package dimensions. Verify pinout compatibility and enable/disable logic polarity. Alternative parts from other manufacturers should be evaluated for equivalent electrical characteristics and thermal performance.
