DS32EL0421SQX/NOPB

Overview

The DS32EL0421SQX/NOPB is a serializer manufactured by Texas Instruments, belonging to the DS32EL0421 series. It functions as a Channel-Link II serialize device with a data rate of 2.1 Gb/s. The component accepts LVDS input signals and provides CML output. It features four inputs and one output. The operating supply voltage ranges from 1.7 V to 3.6 V. The minimum operating temperature is -40°C, and the maximum is +85°C. It is housed in a WQFN-36 package.

Feature Summary

• Converts parallel LVDS data into a high-speed serial CML stream
• Supports data rates up to 2.1 Gb/s for channel-link applications
• Operates within a wide industrial temperature range

Applications

• FPGA link serialization
• High-speed digital interface conversion
• Channel-Link II system integration

Procurement Notes

Verify the manufacturer designation carefully, as the model prefix indicates National Semiconductor while the suffix and current documentation attribute it to Texas Instruments. Confirm the specific package variant (SQX vs SQE) matches the required footprint. Ensure the NOPB lead-free designation aligns with environmental compliance requirements. Cross-reference the datasheet version to confirm pinout compatibility before finalizing procurement orders.

Selection Notes

Select this component when a single-channel serializer is required for FPGA or ASIC interfaces. Compare against the DS92LV0421 if lower speed or different packaging is preferred. Verify that the LVDS input levels and CML output swing match the connected receiver specifications. Check thermal dissipation capabilities within the WQFN-36 enclosure for the target application environment.

Part Context

This part belongs to the DS32EL0421 family of serializers designed for high-speed data transmission. It serves as a bridge between parallel logic domains and serial transmission lines. The device is often used in conjunction with compatible deserializers to extend trace lengths in high-bandwidth systems. It represents a transition product following the National Semiconductor acquisition by Texas Instruments.

Replacement Considerations

The DS92LV0421SQX/NOPB is listed as a parameter equivalent substitute. Verify functional compatibility regarding input/output configurations and electrical characteristics before substitution.
