DS32ELX0421SQX/NOPB

Overview

The DS32ELX0421SQX/NOPB is a serializer manufactured by Texas Instruments, formerly National Semiconductor. It operates within the FPGA-Link family, supporting data rates from 125 MHz to 312.5 MHz. The device accepts five parallel DDR LVDS inputs and converts them into two serial CML outputs. It functions on supply voltages of 2.5 V or 3.3 V. The component is housed in a Leadless Lead Frame Package (LLP) with an exposed pad, suitable for surface mount technology. It supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Supports high-speed serialization of parallel DDR LVDS data interfaces
• Provides dual serial output streams for FPGA link applications
• Compatible with standard 2.5 V and 3.3 V power supplies

Applications

• FPGA parallel interface serialization
• High-speed digital signal transmission links
• Data acquisition systems requiring DDR LVDS input

Procurement Notes

Verify the manufacturer designation as Texas Instruments, which acquired National Semiconductor. Confirm the specific suffix indicates lead-free compliance and tape-and-reel packaging. Ensure the LLP package variant matches the target PCB footprint requirements before ordering.

Selection Notes

Select this component when interfacing FPGAs requiring serialized outputs from parallel DDR LVDS sources. Compare against the DS92LV0421 for lower speed Channel Link II applications. Verify that the required data rate falls within the 125 MHz to 312.5 MHz operational window defined for the FPGA-Link series.

Part Context

This part belongs to the DS32ELX0421 series, designed for high-performance serializing tasks. It complements deserializer counterparts like the DS32EL0124. The lineage traces back to National Semiconductor's analog and mixed-signal portfolio before being integrated into Texas Instruments' interface IC division.

Replacement Considerations

The DS32EL0421SQE-NOPB serves as a direct functional substitute within the same FPGA-Link family. Both devices share identical serialization capabilities and pin configurations.
