DS90C383MTD

Overview

The DS90C383MTD is a programmable LVDS transmitter manufactured by National Semiconductor, now part of Texas Instruments. It functions as a 24-bit Flat Panel Display (FPD) Link transmitter operating at frequencies up to 65 MHz with data rates reaching 1.8 Gb/s. The device accepts LVCMOS or LVTTL inputs and converts them to low-voltage differential signals for transmission. It operates on a single 3.3 V power supply within a range of 3.0 V to 3.6 V. The component is housed in a 56-pin TSSOP package suitable for surface mount installation. It supports an industrial temperature range from -40°C to +85°C and includes features such as programmable output slew rates and termination control.

Feature Summary

• Converts parallel CMOS/TTL data into high-speed LVDS differential signals for display interfaces
• Supports programmable output characteristics including slew rate and termination resistance
• Integrates multiple drivers within a compact surface-mount package for space-constrained designs

Applications

• Flat panel display link transmitters
• LVDS interface circuits for digital video transmission
• High-speed data conversion between logic families and differential lines

Procurement Notes

Verify the specific suffix and revision level when sourcing, as National Semiconductor was acquired by Texas Instruments. Confirm RoHS compliance status and moisture sensitivity levels prior to assembly. Check current lifecycle status, as older variants may be marked as not recommended for new designs. Ensure compatibility with existing PCB footprints for the 56-TSSOP package.

Selection Notes

Select this component when a 24-bit LVDS transmitter is required for FPD-Link applications. Compare against the DS90CF384 receiver counterpart for complete link design. Consider the DS90C383BMT variant if extended commercial temperature ranges are sufficient. Verify input voltage levels match the source logic family, either LVCMOS or LVTTL.

Part Context

This component belongs to the DS90C383 series of LVDS interface integrated circuits originally developed by National Semiconductor. The series includes complementary receivers like the DS90CF384. These devices were designed to facilitate high-speed digital video transmission in flat panel display systems before being integrated into Texas Instruments' portfolio following their acquisition of National Semiconductor.

Replacement Considerations

The DS90C383BMT/NOPB is a documented equivalent within the same functional family. Other compatible parts include the DS90C383A series for similar performance profiles. Verify pinout and electrical specifications against the target application requirements before substitution.
