DS32EL0421SQE/NOPB

Overview

The DS32EL0421SQE/NOPB is a serializer manufactured by Texas Instruments, designed for high-speed data transmission applications. It operates within the Serializers & Deserializers (Serdes) category and supports data rates ranging from 125 MHz to 312.5 MHz, with a maximum serial output rate of 3.125 Gb/s. The device accepts five differential LVDS inputs and converts them into two CML outputs. It functions on dual supply voltages of 2.5 V and 3.3 V. The component is housed in an LLP EP package suitable for surface mount technology and maintains reliable operation across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Supports DDR LVDS parallel input interface for FPGA link connectivity
• Converts low-voltage differential signaling to current-mode logic outputs
• Designed for high-speed serialization up to 3.125 Gb/s

Applications

• FPGA link serializer interfaces
• High-speed data acquisition systems
• Industrial communication equipment

Procurement Notes

Verify the specific suffix NOPB confirms lead-free and RoHS compliance status as per manufacturer documentation. Confirm the LLP EP package variant matches the required footprint for PCB layout. Ensure the operating voltage requirements align with the system's 2.5 V and 3.3 V power rails before integration.

Selection Notes

Select this component when a five-channel LVDS to dual CML serializer is required for FPGA interconnects. Compare against the DS32ELX0421 series for potential pin-compatible or functional alternatives if different packaging or slight parameter variations are acceptable. Verify that the 3.125 Gb/s maximum speed meets the specific bandwidth needs of the application.

Part Context

This part belongs to the DS32EL0421 family of serializers from Texas Instruments. It is functionally related to deserializer counterparts such as the DS32EL0124 series. The SQE suffix indicates a specific tape and reel packaging configuration distinct from other variants like the SQX.

Replacement Considerations

The DS32ELX0421SQE-NOPB is listed as a related variant within the same product family. Cross-reference datasheets to confirm identical electrical characteristics and pinout compatibility before substitution.
