Oscillators Procurement Notes

Verify the specific ordering suffix to ensure the correct frequency and voltage specifications match the design requirements. Confirm that the HCMOS output level is compatible with the target load circuitry. Check for RoHS compliance documentation if environmental regulations apply to the final assembly. Ensure the surface mount footprint matches the PCB layout guidelines provided in the official datasheet.

Oscillators Selection Notes

Select this component when a precise 155.52 MHz clock source is required for high-speed digital interfaces. The HCMOS output is suitable for direct connection to standard logic families without additional buffering. Consider the enable/disable feature if system-level power management is necessary. The wide temperature range makes it suitable for demanding industrial or telecommunications environments.

Oscillators Part Context

This part belongs to the TSM53 series of miniature SMD oscillators from Transko Electronics. The series offers various frequencies and voltage options within a standardized 5.0x3.2x1.3mm package. It is designed as a low-cost solution for applications requiring stable clock signals in space-constrained designs. The family generally supports both HCMOS and TTL outputs depending on the specific model variant.

Oscillators Replacement Considerations

Direct substitutes must match the 155.52 MHz frequency, HCMOS output, 3.3V operation, and 4-SMD package dimensions. Verify that any alternative component maintains the same enable/disable functionality and temperature rating. Cross-reference pinouts to ensure electrical compatibility without PCB redesign.
