DS90LV004TVS

Overview

The DS90LV004TVS is a low-voltage differential signaling (LVDS) interface integrated circuit manufactured by Texas Instruments. It integrates four independent drivers and four receivers, functioning as a buffer or repeater for LVDS signals. The device supports data rates up to 1.5 Gb/s and accepts CML, LVDS, or LVPECL input types while providing LVDS outputs. It operates within a supply voltage range of 3.15 V to 3.45 V, with a typical operating voltage of 3.3 V. The component is housed in a 48-pin TQFP package designed for surface mount technology. It functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Integrates four differential drivers and four receivers for signal buffering and repeating
• Supports high-speed data transmission up to 1.5 Gb/s
• Compatible with multiple input standards including CML, LVDS, and LVPECL

Applications

• High-speed digital video interfaces requiring signal integrity maintenance
• Data acquisition systems utilizing LVDS communication protocols
• Industrial control networks needing robust differential signaling

Procurement Notes

Verify the complete part number including the suffix NOPB when sourcing, as it indicates lead-free compliance and RoHS adherence. Confirm the package type is TQFP-48 and ensure the supplier provides official datasheets matching the DS90LV004 series specifications. Check for moisture sensitivity labeling if storage conditions are a concern.

Selection Notes

Select this component when a quad-channel LVDS buffer or repeater is required for CML, LVDS, or LVPECL inputs. Ensure the application environment stays within the -40°C to +85°C operating range. Verify that the 3.3V power supply tolerance aligns with the 3.15V to 3.45V operational limits specified for reliable performance.

Part Context

This device belongs to the DS90LV004 family of LVDS interface ICs from Texas Instruments. It is distinct from the SCAN90004 series, which shares similar electrical characteristics but may differ in specific functional configurations or pinouts. The DS90LV004 is specifically categorized as a buffer/repeater rather than a crosspoint switch.

Replacement Considerations

The SCAN90004TVS/NOPB is a functionally similar alternative offering identical 1.5 Gb/s data rates and quad driver/receiver configuration in the same TQFP-48 package. Verify pin compatibility and specific internal circuit differences before substitution.
