Oscillators Procurement Notes

Verify the complete part number including the specific frequency suffix (74.963397M) and package code (TCHPA0) against official EPSON documentation. Confirm that the required voltage level (1.8V or 3.3V) matches the system design constraints. Ensure the enable/disable pin configuration aligns with the host controller's logic levels. Cross-reference the RoHS status and MSL rating with project compliance requirements before finalizing procurement.

Oscillators Selection Notes

Select this component when a standard CMOS output is required for frequencies near 75 MHz. The ±20ppm stability suits general-purpose timing needs rather than high-precision RF applications. Consider the 4-SMD footprint for space-constrained PCB layouts. Verify that the 6.8mA typical current draw fits within the system's power budget. Ensure the operating voltage range covers the specific supply rail available in the target circuit design.

Oscillators Part Context

This model belongs to the SG-8101 series of surface-mount crystal oscillators from EPSON. The series is designed for general-purpose clock generation in electronic devices. The SG-8101CE variant specifically denotes the package type and performance characteristics suitable for industrial and commercial applications. It replaces older through-hole or larger surface-mount oscillators in modern miniaturized designs.

Oscillators Replacement Considerations

Direct substitutes must match the 74.963397 MHz frequency, CMOS output, and 4-SMD package dimensions. Check compatibility with the 1.8V-3.3V supply range and ±20ppm stability requirement. Verify that alternative parts support the same enable/disable control mechanism and operate within the -40°C to +105°C temperature range.
