Oscillators Procurement Notes

Verify that the specific part number suffix matches the required frequency tolerance and temperature range specifications. Confirm RoHS compliance status and lead-free certification requirements for your manufacturing process. Ensure the ordering quantity aligns with the tape and reel packaging standards defined by the manufacturer. Cross-reference the datasheet revision date to guarantee access to the most recent electrical parameters and mechanical drawings before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a 48 MHz LVCMOS clock source is required within a 5x3.2 mm footprint. It is appropriate for designs needing ±50 ppm total frequency stability over an industrial temperature range. Consider the 12 mA current draw for power budget calculations. Verify that the load capacitance requirements of the downstream circuitry do not exceed the specified 15 pF limit to maintain signal integrity and duty cycle accuracy.

Oscillators Part Context

This oscillator belongs to the EC36 series of standard SPXO devices from Ecliptek. These components are generally characterized by their ceramic construction and compatibility with standard reflow soldering profiles. The series supports various frequencies and stability grades, catering to both consumer and industrial electronics applications requiring precise timing signals.

Oscillators Replacement Considerations

Direct substitutes must match the 48 MHz frequency, 3.3V LVCMOS output, and 5x3.2mm SMD package dimensions. Verify equivalent ±50 ppm stability and -40°C to +85°C operating range. Check pinout compatibility, specifically the tri-state enable function on Pin 1, to ensure seamless integration without PCB redesign.
