Oscillators Procurement Notes

Verify the specific package dimensions and lead configuration against the official datasheet to ensure compatibility with the target PCB footprint. Confirm that the 1.8V supply voltage aligns with the system's power architecture. Check for RoHS compliance status if environmental regulations apply to the manufacturing process. Ensure the HCMOS output voltage levels match the receiving component's input thresholds.

Oscillators Selection Notes

Select this component when high frequency stability is required over a wide temperature range compared to standard XO oscillators. The small 2.00mm x 1.60mm footprint makes it suitable for space-constrained designs. Consider the 1.8V supply requirement and standby current specifications for battery-operated applications. Verify that the HCMOS output drive capability meets the load requirements of the connected circuitry without additional buffering.

Oscillators Part Context

This part belongs to the CTS Frequency Controls TCXO family, designed to provide superior frequency accuracy compared to basic crystal oscillators. It addresses applications where environmental temperature fluctuations impact timing precision. The series offers various frequencies and packages, with this specific model focusing on the 27 MHz standard used in many legacy and industrial interfaces.

Oscillators Replacement Considerations

Direct substitutes must match the 27 MHz frequency, 1.8V supply, and 4-SMD No Lead package. Verify pinout compatibility and output logic type. Alternative TCXOs from other manufacturers may require level shifting or voltage regulation adjustments.
