Specialty Logic Procurement Notes

Verify the exact suffix configuration as the provided model combines CKLF and T/M designators which may indicate specific tape-and-reel or moisture sensitivity variations. Confirm RoHS compliance status and lead-free certification directly with the manufacturer or authorized distributors, as legacy parts often have complex supply chain histories. Ensure the component matches the required package type and temperature grade for your specific application environment before procurement.

Specialty Logic Selection Notes

Select this component when designing DDR memory interfaces requiring SSTL_2 compatibility and registered buffering for signal integrity. It is suitable for systems utilizing PC1600 through PC3200 memory standards. Consider the 56-pin VFQFPN package constraints for PCB layout. Verify that the voltage domain aligns with the 2.3V-2.7V or 2.5V-2.7V operational requirements specified for different memory speeds.

Specialty Logic Part Context

This part belongs to the SSTVA16859C series of registered buffers designed for high-speed DDR memory applications. It serves as a critical interface component between memory controllers and DRAM chips, ensuring signal stability and timing accuracy. The series is engineered to meet JEDEC standards for SSTL_2 signaling, providing reliable performance in personal computer and server memory subsystems.

Specialty Logic Replacement Considerations

The SSTVF16859B is a documented alternative within the same functional family for DDR memory modules. Verify pinout compatibility and electrical specifications against the original datasheet before substitution. Other variants in the SSTVA16859 series may offer different packaging options but should be evaluated for equivalent performance characteristics.
