SN65LVDS117DGGR

Overview

The SN65LVDS117DGGR is a dual 8-port LVDS repeater manufactured by Texas Instruments. It integrates two identical banks, each containing one differential line receiver and sixteen differential line drivers. The device operates on a single 3 V to 3.6 V supply with a typical current of 122 mA. It supports data signaling rates up to 400 Mbps and clock frequencies up to 400 MHz. Propagation delay is typically 2.8 ns with a maximum of 4.5 ns. The component is housed in a 64-pin TSSOP (DGG) package.

Feature Summary

• Integrates two independent banks for simultaneous signal distribution
• Provides individual enable control for each output pair
• Includes internal fail-safe circuitry for open-circuit detection
• Delivers precise timing alignment through low pulse skew

Applications

• System clock distribution trees
• Data distribution networks
• Point-to-multipoint baseband transmission
• High-speed digital interface buffering

Procurement Notes

Verify the 'R' suffix indicates tape-and-reel packaging with a standard quantity of 2000 units per reel. Confirm the DGG package designation matches the required 64-pin thin shrink small-outline form factor. Ensure the operating temperature range meets the -40°C to +85°C specification for the intended environment.

Selection Notes

Select this part when a dual-bank architecture is required to split signals into multiple paths while maintaining tight timing synchronization. The integrated enable logic allows for selective path activation. Verify that the system requires LVDS signaling standards and can accommodate the specific power dissipation characteristics of the 64-pin package.

Part Context

This component belongs to the SN65LVDS1xx family of LVDS splitters and repeaters. It shares functional similarities with the SN65LVDS109 but offers higher port density with sixteen drivers per bank. Both devices utilize the same underlying LVDS technology for high-speed, low-noise data transmission.

Replacement Considerations

The SN65LVDS117DGG serves as the tube-packaged equivalent. Designers must account for differences in shipping quantities and handling procedures between the tape-and-reel and tube formats.
