Oscillators Procurement Notes

Verify the specific suffix and frequency code against the manufacturer's official datasheet to ensure exact matching of electrical parameters. Confirm that the required operating temperature range aligns with the specified -40°C to +85°C limit. Ensure the target application circuit provides the necessary enable signal if low-power standby modes are required. Cross-reference the package dimensions with the PCB footprint design to guarantee mechanical fit.

Oscillators Selection Notes

Select this component when a precise 4 MHz timing source is required for HCMOS-based digital designs. Consider the ±25 ppm stability specification against the system's tolerance requirements. Evaluate the 40 mA maximum current consumption against available power budgets. Verify that the 3.3 V supply rail is stable within the 2.97 V to 3.63 V operational window to maintain frequency accuracy.

Oscillators Part Context

This part belongs to the MIH series of standard oscillators from MMD (Abracon). The series designation indicates a ceramic package oscillator with specific dimensional constraints. The model number encodes the frequency, with '4.000' representing the 4 MHz output. This family is designed for general-purpose timing applications where moderate stability and standard digital outputs are sufficient.

Oscillators Replacement Considerations

Direct substitutes include other MIH302548AH variants with identical pinouts and specifications but different frequencies, such as MIH302548AH-3.6864MHZ-T or MIH302548AH-24.576MHZ-T, provided the system timing allows for frequency adjustment.
