DS15BA101SDE/NOPB

Overview

The DS15BA101SDE/NOPB is a single-channel differential buffer manufactured by Texas Instruments, designed for high-speed signal integrity applications. It supports data rates up to 2 Gb/s and operates within a supply voltage range of 3.135 V to 3.465 V. The device draws a typical operating current of 45 mA and features adjustable output voltage capabilities to accommodate various load requirements. It utilizes an 8-WSON package with dimensions of 3x3 mm, suitable for surface-mount assembly. The component functions as a non-inverting buffer with CML, LVDS, or LVPECL inputs and CML or LVDS outputs, ensuring compatibility with standard differential signaling interfaces in embedded systems.

Feature Summary

• Adjustable output voltage configuration allows optimization for specific load conditions and signal integrity requirements.
• Supports multiple input standards including CML, LVDS, and LVPECL for flexible interface integration.
• Compact 8-WSON packaging facilitates space-constrained board designs while maintaining thermal performance.

Applications

• Long reach applications for embedded clock serializer/deserializer systems
• LVDS interface buffering in display and video transmission links
• Signal re-driving in high-speed serial communication backplanes

Procurement Notes

Verify the complete part number including the suffix to ensure correct package type and tape/reel specifications. Confirm RoHS compliance status and moisture sensitivity level prior to procurement. Cross-reference the manufacturer's latest datasheet revision to validate electrical parameters against design requirements. Ensure ordering quantities align with available packaging formats such as cut tape or reel options provided by distributors.

Selection Notes

Select this component when a single-channel differential buffer with adjustable output swing is required for LVDS or CML signals. Consider the 8-WSON footprint constraints and verify that the 3.3 V nominal supply voltage matches the system power rails. Evaluate the 2 Gb/s maximum data rate against the target application bandwidth needs. Compare propagation delay characteristics if timing alignment is critical within the signal chain.

Part Context

This device belongs to the DS15BA101 series of differential buffers from Texas Instruments. The series includes variants with different package options such as the SD and SDE suffixes, which denote distinct physical footprints. These components are engineered to extend reach and improve signal quality in high-speed digital interfaces, particularly where standard drivers may suffer from attenuation over longer traces.

Replacement Considerations

The DS15BA101SD/NOPB serves as a pin-compatible alternative with a different package outline. Verify mechanical fit and thermal dissipation characteristics before substitution. Other members of the DS15BA101 family may offer similar electrical performance but require validation of input/output compatibility and package dimensions.
