Oscillators Procurement Notes

Verify the specific ordering suffix TCHPA0 matches the required frequency and package configuration. Confirm that the 18.416 MHz specification aligns with the target circuit design requirements. Ensure compatibility with the 1.8V to 3.3V supply voltage range. Check for any specific environmental or reliability certifications required for the intended application environment before finalizing procurement.

Oscillators Selection Notes

Select this component when a programmable CMOS oscillator with a 4-SMD footprint is required. Consider the enable/disable feature if power efficiency during standby modes is critical. Verify that the 18.416 MHz frequency meets the system clock needs. Evaluate the operating temperature range against the application's environmental conditions to ensure reliable performance throughout the operational lifecycle.

Oscillators Part Context

The SG-8101CA series represents Epson's line of programmable standard crystal oscillators. These components are designed to replace fixed-frequency crystals and resonators, offering greater flexibility in system design. The series is widely used in consumer electronics and industrial equipment where precise timing and small form factors are essential for modern device miniaturization.

Oscillators Replacement Considerations

Direct substitutes include other SG-8101CA variants with identical pinouts and electrical characteristics but different frequencies. Cross-reference with other manufacturers' 4-SMD CMOS oscillators only if pin compatibility and voltage ranges match exactly. Verify that any replacement maintains the same enable/disable logic levels and output drive strength.
