DS92LX2121SQE/NOPB

Serializers, Deserializers Overview

The DS92LX2121SQE/NOPB is a serializer manufactured by Texas Instruments, designed for high-speed data transmission applications. It supports a maximum data rate of 1.05 Gbps and features 21 parallel LVCMOS inputs converting to a single serial CML output. The device operates within a supply voltage range of 1.71 V to 1.89 V or 3 V to 3.6 V, accommodating various system power requirements. It functions reliably across an extended industrial temperature range from -40°C to +85°C. The component is housed in a compact 40-WQFN package with dimensions of 6 mm by 6 mm, suitable for surface-mount assembly in space-constrained designs.

Serializers, Deserializers Feature Summary

• Converts 21-bit parallel LVCMOS data streams into a single serial CML output channel
• Supports Link III interface protocol for direct control serialization
• Operates on dual voltage domains including 1.8 V and 3.3 V supplies
• Engineered for automotive-grade reliability with AEC-Q100 qualification

Serializers, Deserializers Applications

• Automotive camera systems requiring high-bandwidth video transmission
• In-vehicle infotainment display interfaces
• ADAS sensor data aggregation links

Serializers, Deserializers Procurement Notes

Verify the specific suffix E/NOPB to confirm RoHS compliance and lead-free status. Ensure the ordering quantity aligns with the manufacturer's standard packaging specifications. Confirm that the intended operating environment falls within the specified -40°C to +85°C temperature range. Validate that the system power supply voltages match the required 1.71–1.89 V or 3–3.6 V rails before procurement.

Serializers, Deserializers Selection Notes

Select this component when a 21-channel serializer is required for Link III compatible deserializers. Compare against the DS92LV0421 if fewer input channels are sufficient, or the DS92LX1621 if lower data rates suffice. Ensure the PCB layout supports the 40-pin WQFN footprint. Verify that the target application requires CML output signaling rather than LVDS alternatives found in other series members.

Serializers, Deserializers Part Context

This part belongs to the DS92LX2121 family of serializers from Texas Instruments. It is distinct from the DS92LX1621, which offers 16 inputs at 900 Mbps, and the DS92LV0421, which provides 4 inputs at 2.1 Gbps. The DS92LX2121 bridges these capabilities by offering higher channel count than the LX1621 while maintaining compatibility with Link III protocols. Evaluation kits such as the LX21EVK01 are available for development purposes.

Serializers, Deserializers Replacement Considerations

The DS92LV0421SQE/NOPB serves as a parameter-equivalent alternative for applications requiring fewer input channels but higher speed. No direct pin-to-pin replacements with identical channel counts are listed in public distributor databases.
