Serializers, Deserializers Procurement Notes

Verify the exact manufacturer designation, as National Semiconductor assets are now managed by Texas Instruments. Confirm the 64-TQFP package type and the NOPB lead-free status match the design requirements. Ensure the functional description aligns with deserializer applications rather than serializer or transceiver roles. Cross-reference the datasheet specifications against the intended serial-to-parallel conversion speed and voltage levels before finalizing procurement orders.

Serializers, Deserializers Selection Notes

Select this component when a dedicated deserializer function is required to parallelize serial data streams. The 64-pin TQFP package offers a balance of pin count and board space efficiency for complex interfaces. Consider the lead-free construction if environmental compliance is mandatory. Evaluate the specific serial input format compatibility to ensure seamless integration with upstream transmitter components without additional logic buffering.

Serializers, Deserializers Part Context

This component falls under the broader category of interface ICs, specifically serializers and deserializers. These devices facilitate data transfer between high-speed serial buses and parallel processing units. The DS99R122 series represents a specialized solution for converting serialized data flows into parallel formats suitable for microprocessors or memory interfaces, distinct from general-purpose transceivers or simple buffer chips.

Serializers, Deserializers Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with current inventory sources, noting that National Semiconductor operations have transitioned to Texas Instruments. Check for equivalent deserializer functions in the updated product portfolio if direct replacements are unavailable.
