Oscillators Procurement Notes

Verify the specific suffix TJHSA0 against official Epson documentation to confirm voltage, tolerance, and packaging specifications. Ensure the required frequency matches the system design exactly, as oscillators are not generally interchangeable across different frequencies. Confirm RoHS compliance status and check for any regional trade restrictions before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a stable 55.4666 MHz reference is required for CMOS-based digital circuits. Consider the ±50 ppm stability requirement against system timing budgets. Evaluate the 1.8V to 3.3V supply range compatibility with existing power rails. The wide temperature range makes it suitable for applications exceeding standard commercial limits.

Oscillators Part Context

This part belongs to the SG-8018CG series of standard crystal oscillators from Epson Timing. The series offers various frequency options within a consistent 2.5x2.0mm package form factor. It serves as a primary clock source for microprocessors, FPGAs, and memory interfaces where size and power efficiency are critical design constraints.

Oscillators Replacement Considerations

Direct replacements must match the 55.4666 MHz frequency, ±50 ppm stability, and 4-SMD 2.5x2.0mm package dimensions. Verify that alternative sources support the same 1.8V-3.3V supply range and include the standby functionality. Cross-reference pinouts and electrical characteristics to ensure circuit compatibility.
