SN65LVDS117DGGG4

Overview

The SN65LVDS117DGGG4 is a dual 8-port LVDS repeater manufactured by Texas Instruments. It integrates two identical banks, each containing one differential line receiver and eight differential line drivers. The device supports data signaling rates up to 400 Mbps and operates on a single 3-V to 3.6-V supply. It meets ANSI EIA/TIA-644 standards with typical output voltage of 350 mV into a 100-Ω load. Propagation delay is less than 4.5 ns, with part-to-part skew under 1.5 ns. It is housed in a 64-pin TSSOP package.

Feature Summary

• Dual independent banks for simultaneous signal distribution
• Individual enable logic for precise path control
• Integrated fail-safe circuitry for open-circuit detection
• Electrical compatibility with various logic families via termination

Applications

• System clock distribution trees
• Data distribution networks
• Point-to-multipoint baseband transmission

Procurement Notes

Verify the G4 suffix indicates lead-free construction and RoHS compliance. Confirm the DGG package designation matches the required 64-pin thin shrink small-outline form factor. Ensure the operating temperature range aligns with industrial specifications. Validate that the specific revision level meets current manufacturing standards.

Selection Notes

Select this component when high fan-out capability is required for LVDS signals. The dual-bank architecture allows for redundant or separate signal routing. Consider the low power dissipation characteristics for thermal management. Evaluate the tight timing skew requirements against system synchronization needs.

Part Context

This device belongs to the SN65LVDS117 family of LVDS splitters and repeaters. It shares functional similarities with the SN65LVDS109 but offers higher port density. The family is designed for low-power, high-speed differential signaling applications requiring precise timing alignment across multiple outputs.

Replacement Considerations

SN65LVDS117DGG is the non-RoHS equivalent. SN65LVDS109DGG provides similar functionality with fewer ports.
