DS91M040TSQ/NOPB

Overview

The DS91M040TSQ/NOPB is a quad mini-LVDS (M-LVDS) transceiver manufactured by Texas Instruments. It integrates four drivers and four receivers within a single WQFN-32 package, supporting data rates up to 250 Mb/s. The device operates on a single 3.0 V to 3.6 V power supply, with a typical operating voltage of 3.3 V and a maximum power dissipation of 3.91 W. It features LVTTL and M-LVDS input/output types, ensuring compatibility with standard logic interfaces. The component functions reliably across an extended temperature range from -40°C to +85°C, with a propagation delay of 3.3 ns.

Feature Summary

• Integrates four independent drivers and four receivers for high-density signal transmission.
• Supports dual-mode operation with both LVTTL and M-LVDS compatible input and output signals.
• Designed for low electromagnetic interference (EMI) through reduced voltage swing signaling.
• Provides robust performance in industrial environments with wide operating temperature capabilities.

Applications

• High-speed parallel interface connections in embedded systems
• Data acquisition systems requiring reliable multi-channel transmission
• Industrial automation control networks
• Medical imaging equipment signal routing

Procurement Notes

Verify the specific suffix 'SQ' against the manufacturer's latest documentation to confirm package type and moisture sensitivity level requirements. Ensure that the ordering information matches the exact RoHS compliance status and lead-free specifications defined in the official datasheet. Cross-reference the part number with authorized distributors to validate current production status and avoid obsolete stock.

Selection Notes

Select this component when a compact solution for four-channel M-LVDS communication is required. The WQFN-32 package offers space efficiency compared to larger surface-mount options. Consider the 250 Mb/s speed limit and 3.3 V operating voltage when designing power delivery networks. Verify that the system environment stays within the specified -40°C to +85°C operational range for optimal reliability.

Part Context

This device belongs to the DS91M040 series of mini-LVDS transceivers. It serves as a bridge between standard logic levels and differential signaling standards. The family includes evaluation kits such as the DS91M040EVK/NOPB for testing purposes. It is distinct from higher-speed CML or LVPECL buffers like the DS15BR400 series.
