SN65LVDS108DBTR

Overview

The SN65LVDS108DBTR is an eight-port LVDS clock fanout buffer manufactured by Texas Instruments. It operates within a supply voltage range of 3 V to 3.6 V and supports maximum input frequencies up to 400 MHz. The device features a propagation delay of 4.5 ns and utilizes differential Schmitt trigger inputs for signal integrity. It is housed in a 38-pin TSSOP package with dimensions of 9.7 mm length. The component functions as a line transceiver compliant with EIA-644 and TIA-644 standards, designed for high-speed digital applications.

Feature Summary

• Provides eight differential outputs for clock distribution
• Utilizes differential Schmitt trigger inputs for noise immunity
• Supports high-frequency operation up to 400 MHz

Applications

• High-speed data acquisition systems
• Telecommunications infrastructure equipment
• Industrial automation control networks

Procurement Notes

Verify the specific suffix 'R' indicates tape and reel packaging configuration distinct from tube variants. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer prior to ordering. Ensure the procurement channel provides valid traceability documentation for quality assurance purposes.

Selection Notes

Select this component when an eight-channel LVDS fanout solution is required for clock distribution. Compare against similar parts like the SN65LVDS116 if sixteen channels are needed. Verify that the 3.3 V nominal supply voltage aligns with the system design constraints and that the TSSOP package fits the PCB layout requirements.

Part Context

This part belongs to the SN65LVDS108 series of LVDS repeaters and buffers. It serves as a critical interface component for distributing low-voltage differential signaling clocks across multiple loads while maintaining signal timing accuracy and reducing skew in high-speed digital circuits.

Replacement Considerations

Public confirmed substitute part numbers include SN65LVDS108DBTG4 and SN65LVDS108DBT. Verify pin compatibility and electrical specifications before substitution.
