Oscillators Procurement Notes

Verify the specific part number suffix against official Transko documentation to confirm the exact frequency and package variant. Ensure that the 1.8V supply voltage requirement aligns with the target system design. Confirm RoHS compliance status through the manufacturer's latest datasheet or certification documents prior to procurement.

Oscillators Selection Notes

Select this component when a precise 68MHz reference is required for low-voltage logic circuits. The HCMOS output level suits direct interfacing with standard digital inputs. Consider the ±50ppm stability specification relative to system timing tolerance requirements. Evaluate the thermal performance within the specified -40°C to +85°C operational range for the intended environment.

Oscillators Part Context

This model belongs to the TSM22 series of surface-mount oscillators from Transko Electronics. The series offers various frequencies and voltage options. The H50CQ18ST designation indicates specific electrical characteristics including the 1.8V supply and HCMOS output type. This specific variant provides a fixed 68MHz output for standardized timing needs.

Oscillators Replacement Considerations

Cross-reference with other Transko models sharing the same package and voltage if availability is an issue. Verify that substitute parts maintain the 68MHz frequency and HCMOS output levels. Check for identical pinout configurations to ensure mechanical compatibility without PCB redesign.
