Procurement Notes

Verify the specific suffix 'MDJ' against the manufacturer's current datasheet to confirm the exact frequency tolerance and temperature range specifications. Ensure the ordering quantity aligns with the tape and reel packaging requirements specified by the distributor. Cross-reference the part number with the latest revision history to avoid discrepancies in electrical parameters or pinout definitions during procurement.

Selection Notes

Select this component when a low-profile 48MHz clock source is required for 1.8V logic systems. The ±50ppm stability suits general digital applications where tight jitter constraints are not critical. Consider the enable feature if power conservation is necessary. Evaluate the 105°C upper limit against the specific thermal environment of the target application to ensure long-term reliability under operational stress.

Part Context

This oscillator belongs to the QTM216 series, characterized by its small 2.0x1.6mm ceramic package. The series offers various frequencies and voltage options, catering to diverse embedded design needs. The J variant typically denotes specific commercial/industrial grade specifications within the product line, providing a balance between cost and performance for mass-produced electronic devices.

Replacement Considerations

Direct replacements include other 48MHz 1.8V CMOS oscillators in 2016 packages from manufacturers like TXC or SiTime. Verify pin compatibility and output waveform integrity before substitution. Ensure the alternative part meets the same ±50ppm stability and -40°C to 105°C temperature range requirements for equivalent performance.
