Oscillators Procurement Notes

Verify the specific suffix TJHSA0 matches the required frequency and tolerance specifications. Confirm that the 4-SMD package dimensions align with the PCB footprint constraints. Ensure the supply voltage range covers the target system's operational requirements. Check for RoHS compliance status if environmental regulations apply. Validate the lead time against production schedules as manufacturing cycles may vary.

Oscillators Selection Notes

Select this model when a precise 11.155 MHz reference is required for CMOS-based digital logic. Consider the ±50 ppm stability for applications sensitive to clock drift. The wide voltage range allows flexibility in power supply design. Evaluate the thermal performance to ensure operation within the specified -40°C to +105°C range under all load conditions.

Oscillators Part Context

This component belongs to the SG-8018CE PR series of programmable crystal oscillators from Epson Timing. The series is designed for high-reliability timing applications in compact electronic devices. The SG-8018CE variant specifically targets standard CMOS output requirements with low noise characteristics. It serves as a direct replacement for older oscillator generations in modern surface-mount designs.

Oscillators Replacement Considerations

Direct substitutes include other SG-8018CE models with identical pinout and electrical parameters but different frequencies. Cross-reference with SG-8018CA series if pin compatibility differs slightly. Verify that any alternative maintains the same ±50 ppm stability and voltage range.
