SN65LVDS100DGK

Overview

The SN65LVDS100DGK is a low-voltage differential signaling (LVDS) interface integrated circuit manufactured by Texas Instruments. It functions as a repeater or translator with one driver and one receiver, supporting data rates up to 2 Gbps. The device operates on a single 3.3 V supply voltage within a range of 3 V to 3.6 V. It accepts LVDS, CML, or LVPECL input signals and converts them to LVDS outputs. Packaged in an 8-pin VSSOP, it supports surface-mount installation and operates across a temperature range of -40°C to +85°C.

Feature Summary

• Supports high-speed data transmission up to 2 Gbps for demanding digital interfaces
• Provides versatile signal translation capabilities between LVDS, CML, and LVPECL standards
• Operates reliably from a single 3.3 V power supply

Applications

• High-speed serial communication links requiring signal buffering
• Data acquisition systems utilizing differential signaling
• Telecommunications infrastructure equipment

Procurement Notes

Verify the specific suffix 'DGK' corresponds to the tube package variant rather than the 'DGKR' reel version. Confirm that the application environment remains within the specified -40°C to +85°C operating temperature limits. Ensure the input signal source matches the supported LVDS, CML, or LVPECL types to guarantee proper logic level translation and signal integrity.

Selection Notes

Select this component when a single-channel LVDS buffer or translator is required for board-level interconnects. It is suitable for designs needing conversion between different differential logic families while maintaining low power consumption. Consider the VSSOP-8 footprint constraints during PCB layout planning to ensure adequate thermal dissipation and trace routing space for the differential pairs.

Part Context

This part belongs to the SN65LVDS100 family of high-speed differential line drivers and receivers. It complements other Texas Instruments interface solutions designed for TIA/EIA-644 compliance. The DGK package variant distinguishes it from tape-and-reel versions like the DGKR, catering to manual assembly or specific prototyping needs.

Replacement Considerations

The SN65LVDS100DGKR serves as the identical functional alternative packaged in a reel instead of a tube. Designers must verify if the manufacturing process supports tube packaging before substituting.
