SN65LVDS104D

Signal Buffers, Repeaters, Splitters Overview

The SN65LVDS104D is a low-voltage differential signaling (LVDS) repeater manufactured by Texas Instruments. It integrates one differential line receiver and four differential line drivers, enabling signal distribution from a single source to multiple destinations. The device supports data rates up to 400 Mbps or clock frequencies up to 400 MHz. It operates within a supply voltage range of 2.3 V to 3.6 V and functions across an industrial temperature range of -40°C to +85°C. Packaged in an 8-pin SOIC (D) format with dimensions of 4.9 x 3.91 x 1.58 mm, it complies with ANSI/EIA/TIA-644 standards.

Signal Buffers, Repeaters, Splitters Feature Summary

• Provides fan-out capability by converting one differential input into four synchronized LVDS outputs for signal distribution.
• Features high electrostatic discharge (ESD) protection exceeding 16 kV human-body model ratings for enhanced reliability.
• Ensures precise timing alignment with low pulse skew characteristics suitable for clock distribution applications.

Signal Buffers, Repeaters, Splitters Applications

• Clock distribution networks in wireless base stations and network routers.
• Point-to-point baseband data transmission over controlled impedance media such as PCB traces.
• Board-to-board and rack-to-rack data interconnects requiring signal regeneration.

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the specific suffix 'D' corresponds to the SOIC-8 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor declarations prior to integration. Ensure ordering specifications match the required operating temperature range and pinout configuration for the target design.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component when a single LVDS source must drive four distinct loads without signal degradation. It is appropriate for designs requiring low power consumption and noise immunity in high-speed digital environments. Consider alternative packages if board space constraints differ from the standard SOIC footprint requirements.

Signal Buffers, Repeaters, Splitters Part Context

This part belongs to the SN65LVDS10x series, which includes variants like the SN65LVDS105 that accept TTL inputs. The SN65LVDS104 specifically handles differential LVDS inputs, making it distinct within the family for pure LVDS fan-out applications rather than logic-level translation.

Signal Buffers, Repeaters, Splitters Replacement Considerations

The SN65LVDS104DR serves as the tape-and-reel version of this component. Cross-reference with other manufacturers offering 4-port LVDS repeaters only if pin compatibility and electrical parameters are verified against the TI datasheet.
