Oscillators Procurement Notes

Verify the specific ordering suffix against official Taitien documentation to confirm pinout, tolerance, and packaging specifications. Confirm RoHS compliance status and lead time requirements directly with authorized distributors or the manufacturer. Ensure the selected variant matches the required operating temperature range and control voltage parameters for the target application design.

Oscillators Selection Notes

Select this component when a stable 38.88 MHz reference with voltage-tunable frequency adjustment is required. Evaluate the 50 ppm traction rate against system phase noise requirements. Consider the 25% frequency stability specification for environmental variations. Ensure the 3.3 V supply voltage aligns with the host system's power rails and that the CMOS output drive strength meets load requirements.
