Procurement Notes

Verify component authenticity through authorized distributors or official Infineon channels due to obsolete status. Confirm lot traceability and storage conditions given moisture sensitivity classification. Request detailed datasheets and migration guides from Infineon for integration planning. Ensure compliance with regional regulatory requirements prior to procurement. Validate package integrity upon receipt to prevent handling damage.

Selection Notes

Select this component only when specific compatibility with the HOTLink protocol and 400 Mbps data rate is required. Consider the 28-pin PLCC package constraints for PCB layout design. Evaluate thermal management capabilities within the 0°C to +70°C operational range. Assess system power supply stability to maintain operation within the 4.5V to 5.5V specification limits. Review obsolescence status for long-term production viability.

Part Context

The CY7B923 series belongs to Infineon's HOTLink family of transceivers, previously developed under Cypress Semiconductor before acquisition. This specific model serves as a transmitter variant within that lineage, targeting high-performance serial interconnects. The product line has been succeeded by newer generations such as HOTLink II, reflecting technological evolution in serial interface solutions.

Replacement Considerations

Official substitutes include CY7B923-400JXC and CY7B923-400JXI. Migration to HOTLink II devices is recommended for new designs. Verify pinout and electrical compatibility before substituting. Consult Infineon documentation for detailed transition guidelines.
