Oscillators Procurement Notes

Verify the specific suffix 'B' in the part number to confirm the 3.3V supply voltage requirement, as other variants may operate at different voltages. Ensure the design includes a pull-up resistor on the OE pin to prevent floating states and potential electrostatic damage during idle periods. Confirm that the PCB footprint matches the 4-SMD no-lead package dimensions specified in the official datasheet to ensure proper soldering and mechanical stability.

Oscillators Selection Notes

Select this component when a precise 2.176 MHz clock source is required for power line communication or specialized industrial protocols. It is suitable for designs needing low power consumption and reliable performance across wide temperature variations. Consider the ±30 ppm total drift specification to ensure compatibility with the receiving circuit's jitter tolerance. This model is appropriate for replacing older through-hole oscillators where board space reduction is a priority.

Oscillators Part Context

This oscillator belongs to the SX series of surface-mount crystal oscillators from Shenzhen SCTF Electronics. The series offers various frequencies and voltage options, with the 'B' suffix typically denoting the 3.3V supply variant. These components are designed to replace discrete crystal circuits with integrated solutions, providing better stability and reduced assembly complexity for modern electronic devices requiring precise timing signals.

Oscillators Replacement Considerations

Public confirmed substitute part numbers: S7D2.176000B20F30T (Xingtong Time Frequency). Verify pinout compatibility and thermal characteristics before substitution. Ensure the replacement maintains the same 3.3V supply and CMOS output level requirements.
