Application Specific Clock/Timing Procurement Notes

Verify the complete part number including the suffix 'PWR' to ensure the correct TSSOP-28 package variant is procured. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor certificates prior to ordering. Ensure that the design-in process accounts for the specific 133MHz input requirement and 800MHz output capability defined in the technical specifications to avoid integration errors.

Application Specific Clock/Timing Selection Notes

Select this component when designing systems requiring dedicated clock generation for XDR memory technologies. It is suitable for applications needing a fixed 133MHz to 800MHz frequency conversion with differential signaling capabilities. Consider the 28-TSSOP package constraints and thermal requirements during PCB layout. This IC is appropriate for server and storage solutions utilizing Rambus memory standards where precise timing integrity is critical for data throughput.

Application Specific Clock/Timing Part Context

The CDCD5704PWR belongs to Texas Instruments' family of clock and timing integrated circuits specialized for memory applications. It addresses the specific timing needs of next-generation high-bandwidth memory interfaces. Unlike general-purpose oscillators, this device functions as a programmable multiplier tailored for Rambus protocols. It complements other timing components in the system by providing a stable, high-frequency reference signal derived from a lower-frequency input source.
