Oscillators Procurement Notes

Verify the specific suffix 'B' against official datasheets to confirm pinout and electrical characteristics, as variations exist within the series. Ensure the 3.3V supply requirement aligns with target circuit design. Confirm the SMD7050-4P footprint compatibility during PCB layout. Cross-reference the ±20 ppm stability specification with application requirements for precision timing needs.

Oscillators Selection Notes

Select this component when a 18.432 MHz reference is required with moderate stability. The 3.3V logic level makes it suitable for modern digital systems. The enable feature allows for power optimization in battery-operated devices. Consider the thermal range of -40°C to +85°C for industrial or consumer applications requiring wide temperature operation.

Oscillators Part Context

This oscillator belongs to the SX7M series from Shenzhen SCTF Electronics, designed for general-purpose timing applications. The series offers various frequencies and packages.
