SN65LVDS101DGK

Overview

The SN65LVDS101DGK is a low-voltage differential signaling (LVDS) translator and repeater manufactured by Texas Instruments. It operates within a supply voltage range of 3 V to 3.6 V, with a typical operating voltage of 3.3 V. The device supports data rates up to 2 Gb/s and accepts CML, LVDS, or LVPECL input signals, converting them to LVPECL outputs. Key electrical parameters include a maximum propagation delay of 0.9 ns, an operating power current of 90 mA, and a power dissipation of 377 mW. It functions reliably across a temperature range of -40 °C to +85 °C and is housed in an 8-pin VSSOP package.

Feature Summary

• Translates between multiple single-ended and differential signaling standards including CML, LVDS, and LVPECL
• Provides high-speed signal transmission capabilities suitable for demanding interface applications
• Offers low jitter performance to maintain signal integrity at high data rates

Applications

• High-speed serial communication interfaces requiring protocol translation
• Data acquisition systems utilizing differential signaling
• Test and measurement equipment needing precise timing and signal conversion

Procurement Notes

Verify the specific ordering suffix against official Texas Instruments documentation to ensure correct package type and tape/reel specifications. Confirm RoHS compliance status through the manufacturer's datasheet rather than distributor summaries. Ensure the component matches the required industrial temperature range and pinout configuration for your PCB design before finalizing procurement orders.

Selection Notes

Select this component when interfacing between different logic families such as converting LVDS inputs to LVPECL outputs. Consider the 2 Gb/s data rate capability and 0.9 ns propagation delay for timing-sensitive designs. Evaluate the 90 mA power consumption against thermal constraints in the VSSOP-8 package. Verify that the 3 V to 3.6 V supply range aligns with the system power architecture.

Part Context

This part belongs to the SN65LVDS101 series of LVDS interface integrated circuits from Texas Instruments. The series includes variants like the SN65LVDS100 and SN65CML100, which offer similar translation functions but may differ in output types or specific electrical characteristics. These devices are designed for high-performance digital interfaces requiring reliable signal conversion between various low-voltage differential standards.

Replacement Considerations

Check for direct equivalents within the same family, such as the SN65LVDS100, ensuring output compatibility. Verify pin-to-pin compatibility if substituting with other LVDS translators. Confirm that alternative components meet the same 2 Gb/s speed and temperature requirements.
