DS32ELX0421SQE/NOPB

Overview

The DS32ELX0421SQE/NOPB is a serializer manufactured by Texas Instruments, designed for high-speed data transmission applications. It operates within a frequency range of 125 MHz to 312.5 MHz, supporting data rates up to 3.125 Gb/s. The device accepts LVDS parallel input and converts it to CML serial output. It features five inputs and two outputs, powered by operating supply voltages of 2.5 V or 3.3 V. The component is housed in an LLP EP package and supports surface mount installation. It functions reliably across a temperature range from -40°C to +85°C.

Feature Summary

• Converts low-voltage differential signaling parallel data into current-mode logic serial streams
• Supports FPGA link interface standards with DDR LVDS parallel input capability
• Operates at frequencies up to 312.5 MHz for high-bandwidth data transfer

Applications

• FPGA-Link serializer interfaces
• High-speed digital data transmission systems
• Parallel-to-serial data conversion modules

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct package type and environmental rating. Confirm that the NOPB designation aligns with lead-free compliance requirements for your assembly process. Cross-reference the part number with the latest datasheet revision to validate pinout compatibility and electrical specifications before procurement.

Selection Notes

Select this component when interfacing LVDS sources with CML destinations in FPGA architectures. Ensure the system power supply matches the specified 2.5 V or 3.3 V operating voltage. Verify that the thermal management design accommodates the LLP EP package constraints within the -40°C to +85°C operational range.

Part Context

This device belongs to the DS32ELX series of serializers from Texas Instruments. It is specifically engineered for FPGA link applications requiring high-speed serialization. The part integrates parallel-to-serial conversion capabilities optimized for low-power, high-density board layouts typical in modern digital communication hardware.

Replacement Considerations

The DS32ELX0421SQE/NO is a variant without the NOPB suffix. Verify functional equivalence through official cross-reference tools. No other direct substitutes are confirmed in public documentation.
