Oscillators Procurement Notes

Verify the specific frequency suffix matches the required 18.432 MHz specification. Confirm that the TJHSA0 suffix aligns with the desired packaging format, typically cut tape or reel options available from distributors. Ensure the operating temperature range of -40°C to +105°C meets the environmental requirements of the target application before finalizing the order.

Oscillators Selection Notes

Select this model when a precise 18.432 MHz clock signal is required for digital interfaces. The ±50 ppm stability is suitable for general-purpose timing applications. Consider the low standby current if power management is critical. The wide supply voltage range simplifies integration into mixed-voltage designs without level shifting components.
