DS32EL0421SQ/NOPB

Overview

The DS32EL0421SQ/NOPB is a serializer manufactured by Texas Instruments, operating within the Serializers & Deserializers (Serdes) category. It functions as an FPGA Link Serializer supporting data rates from 125 MHz to 312.5 MHz. The device accepts five LVDS inputs and provides two CML outputs. It operates on supply voltages of 2.5 V or 3.3 V. The component supports surface mount installation in an LLP EP package and maintains functionality across an operating temperature range of -40°C to +85°C.

Feature Summary

• Converts parallel LVDS data into high-speed serial CML streams for FPGA interconnects
• Supports dual-channel output configuration with five differential input channels
• Designed for low-power operation compatible with standard FPGA link interfaces

Applications

• FPGA-to-FPGA high-speed data links
• High-definition video signal transmission systems
• Industrial control network interconnects

Procurement Notes

Verify the manufacturer designation carefully, as National Semiconductor was acquired by Texas Instruments; official documentation lists Texas Instruments as the current producer. Confirm the specific suffix 'SQ' against the datasheet to ensure correct pinout and package variant matching. Check RoHS compliance status via the NOPB designation confirmation. Validate the operating voltage requirements against your system's power rails before integration.

Selection Notes

Select this component when interfacing LVDS sources with CML-compatible FPGA receivers requiring up to 3.125 Gb/s throughput. Ensure the design accommodates the LLP EP package footprint and thermal dissipation needs. Compare against the DS32ELX0421 series if DDR interface support is required instead of standard LVDS serialization. Verify that the 2.5V/3.3V supply options align with the target board architecture.

Part Context

This part belongs to the DS32EL0421 family of serializers designed for high-speed digital interfaces. It complements deserializer counterparts like the DS32EL0124 series to form complete Serdes links. The device is part of Texas Instruments' broader portfolio of interface solutions for consumer and industrial electronics requiring reliable high-bandwidth data transfer.

Replacement Considerations

The DS32EL0421SQE/NOPB is a documented parameter-equivalent substitute offering identical electrical characteristics and pin compatibility.
